Digestion of crystalline cellulose substrates by the clostridium thermocellum cellulosome: structural and morphological aspects. (1/162)The action of cellulosomes from Clostridium thermocellum on model cellulose microfibrils from Acetobacter xylinum and cellulose microcrystals from Valonia ventricosa was investigated. The biodegradation of these substrates was followed by transmission electron microscopy, Fourier-transform IR spectroscopy and X-ray diffraction analysis, as a function of the extent of degradation. The cellulosomes were very effective in catalysing the complete digestion of bacterial cellulose, but the total degradation of Valonia microcrystals was achieved more slowly. Ultrastructural observations during the digestion process suggested that the rapid degradation of bacterial cellulose was the result of a very efficient synergistic action of the various enzymic components that are attached to the scaffolding protein of the cellulosomes. The degraded Valonia sample assumed various shapes, ranging from thinned-down microcrystals to crystals where one end was pointed and the other intact. This complexity may be correlated with the multi-enzyme content of the cellulosomes and possibly to a diversity of the cellulosome composition within a given batch. Another aspect of the digestion of model celluloses by cellulosomes is the relative invariability of their crystallinity, together with their Ialpha/Ibeta composition throughout the degradation process. Comparison of the action of cellulosomes with that of fungal enzymes indicated that the degradation of cellulose crystals by cellulosomes occurred with only limited levels of processivity, in contrast with the observations reported for fungal enzymes. The findings were consistent with a mechanism whereby initial attack by a cellulosome of an individual cellulose crystal results in its 'commitment' towards complete degradation. (+info)
The respiratory system and diazotrophic activity of Acetobacter diazotrophicus PAL5. (2/162)The characteristics of the respiratory system of Acetobacter diazotrophicus PAL5 were investigated. Increasing aeration (from 0.5 to 4.0 liters of air min(-1) liter of medium(-1)) had a strong positive effect on growth and on the diazotrophic activity of cultures. Cells obtained from well-aerated and diazotrophically active cultures possessed a highly active, membrane-bound electron transport system with dehydrogenases for NADH, glucose, and acetaldehyde as the main electron donors. Ethanol, succinate, and gluconate were also oxidized but to only a minor extent. Terminal cytochrome c oxidase-type activity was poor as measured by reduced N, N,N,N'-tetramethyl-p-phenylenediamine, but quinol oxidase-type activity, as measured by 2,3,5,6-tetrachloro-1,4-benzenediol, was high. Spectral and high-pressure liquid chromatography analysis of membranes revealed the presence of cytochrome ba as a putative oxidase in cells obtained from diazotrophically active cultures. Cells were also rich in c-type cytochromes; four bands of high molecular mass (i.e., 67, 56, 52, and 45 kDa) were revealed by a peroxidase activity stain in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. KCN inhibition curves of respiratory oxidase activities were biphasic, with a highly resistant component. Treatment of membranes with 0.2% Triton X-100 solubilized c-type cytochromes and resulted in a preparation that was significantly more sensitive to cyanide. Repression of diazotrophic activity in well-aerated cultures by 40 mM (NH(4))(2)SO(4) caused a significant decrease of the respiratory activities. It is noteworthy that the levels of glucose dehydrogenase and putative oxidase ba decreased 6. 8- and 10-fold, respectively. In these cells, a bd-type cytochrome seems to be the major terminal oxidase. Thus, it would seem that glucose dehydrogenase and cytochrome ba are key components of the respiratory system of A. diazotrophicus during aerobic diazotrophy. (+info)
Acid hydrolysis of bacterial cellulose reveals different modes of synergistic action between cellobiohydrolase I and endoglucanase I. (3/162)Intact and partially acid hydrolyzed cellulose from Acetobacter xylinum were used as model substrates for cellulose hydrolysis by 1,4-beta-D-glucan-cellobiohydrolase I (CBH I) and 1,4-beta-D-endoglucanase I (EG I) from Trichoderma reesei. A high synergy between CBH I and EG I in simultaneous action was observed with intact bacterial cellulose (BC), but this synergistic effect was rapidly reduced by acid pretreatment of the cellulose. Moreover, a distinct synergistic effect was observed upon sequential endo-exo action on BC, but not on bacterial microcrystalline cellulose (BMCC). A mechanism for endo-exo synergism on crystalline cellulose is proposed where the simultaneous action of the enzymes counteract the decrease of activity caused by undesirable changes in the cellulose surface microstructure.

Identification of essential amino acids in the bacterial alpha -mannosyltransferase aceA. (4/162)The alpha-mannosyltransferase AceA from Acetobacter xylinum belongs to the CaZY family 4 of retaining glycosyltransferases. We have identified a series of either highly conserved or invariant residues that are found in all family 4 enzymes as well as other retaining glycosyltransferases. These residues included Glu-287 and Glu-295, which comprise an EX(7)E motif and have been proposed to be involved in catalysis. Alanine replacements of each conserved residue were constructed by site-directed mutagenesis. The mannosyltransferase activity of each mutant was examined by both an in vitro transferase assay using recombinant mutant AceA expressed in Escherichia coli and by an in vivo rescue assay by expressing the mutant AceA in a Xanthomonas campestris gumH(-) strain. We found that only mutants K211A and E287A lost all detectable activity both in vitro and in vivo, whereas E295A retained residual activity in the more sensitive in vivo assay. H127A and S162A each retained reduced but significant activities both in vitro and in vivo. Secondary structure predictions of AceA and subsequent comparison with the crystal structures of the T4 beta-glucosyltransferase and MurG suggest that AceA Lys-211 and Glu-295 are involved in nucleotide sugar donor binding, leaving Glu-287 of the EX(7)E as a potential catalytic residue.

Characterization of a major cluster of nif, fix, and associated genes in a sugarcane endophyte, Acetobacter diazotrophicus. (5/162)A major 30.5-kb cluster of nif and associated genes of Acetobacter diazotrophicus (syn. Gluconacetobacter diazotrophicus), a nitrogen-fixing endophyte of sugarcane, was sequenced and analyzed. This cluster represents the largest assembly of contiguous nif-fix and associated genes so far characterized in any diazotrophic bacterial species. Northern blots and promoter sequence analysis indicated that the genes are organized into eight transcriptional units. The overall arrangement of genes is most like that of the nif-fix cluster in Azospirillum brasilense, while the individual gene products are more similar to those in species of Rhizobiaceae or in Rhodobacter capsulatus.

Gluconacetobacter entanii sp. nov., isolated from submerged high-acid industrial vinegar fermentations. (6/162)Acetic acid bacteria have been isolated from submerged high-acid spirit vinegar fermentations in the Southern part of Germany. Four strains (LTH 4560T, LTH 4341, LTH 4551 and LTH 4637) were characterized in more detail and it was revealed that they have in common certain properties such as requirement of acetic acid, ethanol and glucose for growth, and no over-oxidation of acetate. Growth occurs only at total concentrations (sum of acetic acid and ethanol) exceeding 6.0%. A method for their preservation was developed. Comparative analysis of the 16S rRNA revealed sequence similarities of >99% between strain LTH 4560T and the type strains of the related species Gluconacetobacter hansenii. However, low levels of DNA relatedness (<41 %) were determined in DNA-DNA similarity studies. In addition, specific physiological characteristics permitted a clear identification of the strains within established species of acetic acid bacteria. The strains could also be differentiated on the basis of the distribution of IS element 1031 C within the chromosome. Based on these results, the new species Gluconacetobacter entanii sp. nov. is proposed for strain LTH 4560T ( = DSM 13536T). A 16S-rRNA-targeted oligonucleotide probe was constructed that was specific for G. entanii, and the phylogenetic position of the new species was derived from a 16S-rRNA-based tree. (+info)

The significance of growth on mannitol agar and the presence of a ubiquinone isoprenologue composed of Q-10 is discussed for characterization of the genus Gluconacetobacter. (+info)
Characterization of acetic acid bacteria in traditional acetic acid fermentation of rice vinegar (komesu) and unpolished rice vinegar (kurosu) produced in Japan. (8/162)Bacterial strains were isolated from samples of Japanese rice vinegar (komesu) and unpolished rice vinegar (kurosu) fermented by the traditional static method. Fermentations have never been inoculated with a pure culture since they were started in 1907. A total of 178 isolates were divided into groups A and B on the basis of enterobacterial repetitive intergenic consensus-PCR and random amplified polymorphic DNA fingerprinting analyses. The 16S ribosomal DNA sequences of strains belonging to each group showed similarities of more than 99% with Acetobacter pasteurianus. Group A strains overwhelmingly dominated all stages of fermentation of both types of vinegar. Our results indicate that appropriate strains of acetic acid bacteria have spontaneously established almost pure cultures during nearly a century of komesu and kurosu fermentation. (+info)
Acetobacter aceti - microbewiki
Acetobacter aceti has yet to be reported as a pathogenic microbe to humans or animals. Acetobacter aceti does not produce any toxins, enzymes, or any viruses that harm any human or animal. Since Acetobacter aceti is ubiquitous in nature and there is contact of this bacterium on all animals on a frequent basis. Acetobacter aceti is not a portion of normal flora of bacteria on human skin. The only potential pathology it could present is if presented in mass quantities, an allergic or immune response could occur. Acetobacter aceti does produce alcohols, meaning if consumed in large quantities, these alcohols could affect the central nervous system, causing intoxication via alcohol, a byproduct of Acetobacter aceti, although alcoholism or intoxication is not due to the bacterium. Acetobacter aceti is known to cause rotting and browning discoloration in fruits such as apples, pears, and citrus products. Acetobacter aceti is known for causing pink disease in pineapple, which is the turning of the ...
Acetobacter - Wikipedia
Acetobacter is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus Acetobacter is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water. Bacteria of the genus Acetobacter have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation starter cultures. In 1998, two strains of Acetobacter isolated from red wine and cider vinegar were named Acetobacter oboediens and Acetobacter pomorum. In 2000, Acetobacter oboediens and Acetobacter intermedius were transferred to Gluconacetobacter on the basis of 16S rRNA sequencing. In 2002, Acetobacter cerevisiae and Acetobacter malorum were identified by 16S rRNA sequence analysis of Acetobacter strains. In 2006, a strain of Acetobacter isolated from spoiled red wine was named Acetobacter oeni. Parte, A.C. Acetobacter. www.bacterio.net. Cleenwerck I; Vandemeulebroecke ...
Induction by ethanol of alcohol dehydrogenase activity in Acetobacter pasteurianus. | Journal of Bacteriology
The membrane-bound alcohol dehydrogenase (ADH) activity of Acetobacter pasteurianus NCI1380 was enhanced more than 10-fold by the addition of ethanol to the medium. In order to elucidate the mechanism of the ethanol induction, a gene cluster encoding the dehydrogenase and cytochrome c subunits of ADH was cloned from this strain, and its nucleotide sequence was determined. Comparison of the deduced amino acid sequences and the NH2-terminal sequences determined with purified proteins showed that the dehydrogenase and cytochrome c subunits contained typical signal peptides of 35 and 26 amino acids, respectively. Transcriptional analysis of the cloned genes by primer extension revealed that the gene cluster was transcribed from two different promoters upstream from the dehydrogenase gene. One (59 bp upstream of the ATG start codon) of the two promoters was used in the presence of ethanol, whereas the other (232 bp upstream of the ATG start codon) was used in the absence of ethanol. Immunoblot ...
Controlled secretion into the culture medium of a hybrid beta-glucanase by Acetobacter methanolicus mediated by the kil gene of...
A Tn5-based transposon bearing the kil gene (killing protein), mediating controlled export of periplasmic proteins into the culture medium, was constructed (Tn5-KIL3). This transposon contained the kil gene of the ColE1 plasmid under the growth-phase-dependent promoter of the fic gene (filamentation induced by cAMP) of Escherichia coli, an interposon located upstream of kil, a kanamycin/neomycin-resistance gene, a multiple cloning site and the mob site. The transposition of Tn5-KIL3 to Acetobacter methanolicus showed a moderate transposition frequency (10(-5)-10(-6)). By insertion of a Bacillus hybrid beta-glucanase (bgl) as a model protein into the transposon (Tn5-LF3) it was shown that the secretion function as well as the gene of the target protein had been transferred to and stably integrated into the chromosome of A, methanolicus, and that the transposition of Tn5-LF3 was non-specific. beta-Glucanase was highly overexpressed and secreted into the medium during stationary phase.

Optimization of Acetic Acid Production Rate by Thermotolerant Acetobacter spp. » BLOG - Scientific Research Publishing
Thermotolerant microorganisms were collected, identified and characterized under different physiological conditions from various rotten fruits in Bangladesh for vinegar production. Among the 15-isolates characterized previously, the strains F-1, F-3 and F-10 represented Staphylococcus, Bacillus and Acetobacter spp., respectively. After checking various parameters for growth, acetic acid production rate was optimized further. Among the 3-starins analyzed here, the strain F-10 gave maximum acetic acid (7.0 g/100 ml) at 37°C in 2% ethanol concentration. The strain F-10 is capable of producing high yield of acetic acid at relatively high temperature, which is an ideal condition for vinegar production, which may reduce the water cooing expenses as well as the risk of contamination.. ...

KEGG PATHWAY: Citrate cycle (TCA cycle) - Acetobacter pasteurianus IFO 3283-07
The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...
Acetobacter - microbewiki
In Japan, the polished rice vinegar komesu and the unpolished rice vinegar kurosu are traditional seasonings that are made through saccharification of rice, alcohol fermentation, and oxidation of ethanol to acetic acid. The traditional and most common method for producing these vinegars is called static surface acetic acid fermentation: an alcoholic liquid with vinegar, called moromi, is fermented in covered containers to prevent bacterial contamination; after a few days, a crepe pellicle of acetic acid bacteria, which are generally in the Acetobacter genera, covers the moromi surface and the fermentation is allowed to continue for about a month. Weak acid acetate is a typical product of microbial metabolism and is known for its cytotoxic effects like the retardation of growth. This is related to the weak lipophilic nature of the undissociated acid that enables the molecule to cross the cytoplasmic membrane (Steiner and Sauer 2001). This movement of molecules is thought to throw off ion ...
Acidophile - Wikipedia
Most acidophile organisms have evolved extremely efficient mechanisms to pump protons out of the intracellular space in order to keep the cytoplasm at or near neutral pH. Therefore, intracellular proteins do not need to develop acid stability through evolution. However, other acidophiles, such as Acetobacter aceti, have an acidified cytoplasm which forces nearly all proteins in the genome to evolve acid stability. For this reason, Acetobacter aceti has become a valuable resource for understanding the mechanisms by which proteins can attain acid stability. Studies of proteins adapted to low pH have revealed a few general mechanisms by which proteins can achieve acid stability. In most acid stable proteins (such as pepsin and the soxF protein from Sulfolobus acidocaldarius), there is an overabundance of acidic residues which minimizes low pH destabilization induced by a buildup of positive charge. Other mechanisms include minimization of solvent accessibility of acidic residues or binding of ...

Lambic beer production processes are characterized by a temporal succession of well-adapted microbial species. Temporal metagenomic analysis of a Belgian, traditional, lambic beer production process, which was examined microbiologically and metabolomically before, confirmed that the microbial diversity is limited. Moreover, it allowed to link the consumption and production of certain compounds to specific microbial groups or species. Fermentation characteristics, such as the conversion of malic acid into lactic acid and acetoin production, were retrieved and could be attributed to specific microorganisms, namely Pediococcus damnosus and Acetobacter species, respectively. Traits previously ascribed to brewery-specific Dekkera bruxellensis strains were confirmed during the lambic beer production process examined multiphasically; in particular, the higher production of 4-ethylguaiacol compared to 4-ethylphenol was further shown by mass spectrometric analysis. Moreover, the absence of phenolic acid

Forget sperm and eggs, researchers have created embryo stem cells from skin cells - American Friends of the Hebrew University
A new, groundbreaking study by the Hebrew University of Jerusalem (HU) found a way to transform skin cells into the three major stem cell types that comprise early-stage embryos. This work has significant implications for modeling embryonic disease and placental dysfunctions, as well as paving the way to create whole embryos from skin cells.. As published in Cell Stem Cell, Dr. Yossi Buganim of HUs Department of Developmental Biology and Cancer Research and his team discovered a set of genes capable of transforming murine skin cells into all three of the cell types that comprise the early embryo: the embryo itself, the placenta and the extraembryonic tissues, such as the umbilical cord. In the future, it may be possible to create entire human embryos out of human skin cells, without the need for sperm or eggs. This discovery also has vast implications for modeling embryonic defects and shedding light on placental dysfunctions, as well as solving certain infertility problems by creating human ...

In this study we report on an MGWA analysis to predict bacterial genes that influence the association with the fruit fly D. melanogaster, the creation of a mapped and arrayed transposon insertion library to identity gene-specific insertions in A. fabarum DsW_054, and the use of the mutant library to test the MGWA-predictions. The library includes 6,418 mutants that were mapped to 1,625 genes and 859 intergenic insertions. A 100% validation rate suggested a high accuracy rate of the mapping. Also, near-saturating coverage of non-essential genes allowed us to make inferences about which genes are essential for A. fabarum DsW_054 growth on mMRS medium. Finally, the host-association tests confirmed the prediction that bacterial LPS biosynthesis genes influence bacterial load in the fruit fly, and identified Lipid A biosynthesis genes as key players for these effects. Follow-up experiments that utilize the rich resources available for interrogating host-microbe interactions in Drosophila are ...
iBoot heap internals
Bootchains heap implementation employs several well-known security mitigations in order to detect random heap corruptions and harden exploit development for heap-based vulnerabilities. 1. Heap uses a 128-bit random cookie which is stored in the data section. The cookie is used for initial randomization of the heap placement and verification of heap metadata checksums. On older devices (A7 and earlier) SecuROM and LLB use a statically initialized heap cookie: [ 0x64636b783132322f, 0xa7fa3a2e367917fc ]. Note: the cookie is placed at the top of the data section, as the heap is initialized early. It will not be corrupted by a data-to-heap overflow. 2. Initial heap placement may be randomized with 24 bits of entropy, resulting in a random shift of the heap arena by at most 0x3ffc0 bytes against the data section or wherever else it is placed. In LLB and SecuROM the shift is not randomized on older devices (up to and inclusive A7). 3. There is no runtime randomization in the allocation algorithm. All ...

Selective Vaccination | Āgenskalna privātklīnika
With the current outbreak of the flu season in Israel, hospitals are reporting overcrowding, and doctors are advising people who have not yet been vaccinated against flu to get their shots.. Surprisingly, however, three physicists - one from the Hebrew University of Jerusalem and two others from Michigan State University - have developed an unconventional, theoretical strategy for intensive but limited vaccination against infectious diseases (such as flu) that would replace the practice of mass inoculation over a prolonged period. The physicists developed their theory using a technique borrowed from quantum mechanics.. How does it work? The program is based on accelerating the natural extinction of the disease through selective vaccination.. Prof. Baruch Meerson of the Racah Institute of Physics at the Hebrew University explains the strategy:.

Hebrew Universitys Methylation Maestro | CFHU
Lab rat. Cedar says he was not the best student in NYUs MD/PhD program, but he did enjoy learning about the life sciences. I was infatuated with general biology principles. It was the beginning of the molecular biology revolution, says Cedar. After three years of medical school and clinical rotations, Cedar chose to work with James Schwartz, who started at NYU as a microbiologist and then became a neurobiologist, using the sea slug Aplysia to study how memory works. Part of Schwartzs research included examining how learning affects chromatin structure. Cedar was Schwartzs first graduate student. Its very good to be the first graduate student; you get a lot of attention, says Cedar. He studied E. colis synthesis of L-asparaginase, which catalyzes the hydrolysis of the amino acid asparagine to aspartic acid, and purified asparagine synthetase from the bacterium to study how that enzyme catalyzes the reverse reaction, using aspartate to produce the amino acid in vitro. Cedar enjoyed ...

Production of Bacterial Cellulose by Acetobacter xylinum through Utilizing Acetic Acid Hydrolysate of Bagasse as Low-cost Carbon Source. Zheng Cheng,a,b Rendang Yang,a,b,* and Xiao Liu a,b. Bacterial cellulose (BC) is a promising and renewable nanomaterial due to its unique structural features and appealing properties. Intensive study on BC preparation has been mainly focused on biosynthesis by certain bacteria, while the high economic costs of fermentation, especially the carbon sources, remain challenges to its application. In this study, bacterial cellulose was synthesized by Acetobacter xylinum with the acetic acid hydrolysate of bagasse used as carbon source. After the bagasse was pretreated by acetic acid, the components in hydrolysate and the removal rate was investigated, and the pretreatment conditions were optimized as follows: temperature of 160 °C, heating time of 60 min, addition of acetic acid of 2.0% (m/m), and solid-to-liquid ratio of 1/5. Prior to Acetobacter xylinum ...
Mathematical modelling of bacterial cellulose production by acetobacter xylinum using rotating biological fermentor
Bacterial cellulose (BC) has a basic cellulose structure that gives high purity, high crystalline ability, high mechanical strength, and high water holding capacity. During the last few decades, BC has gained as an important biomaterial because of these unique physical and chemical characteristics. BC is synthesized by Acetobacter xylinum extracellularly in a suitable substrate media. Researchers have produced BC using a synthetic media or using coconut water and inoculating with Acetobacter xylinum in a static fermentation system. In order to eliminate shortcomings in static fermentation and to achieve increased cellulose production, agitated and aerated fermentation systems were experimented. Rotating Biological Fermentor (RBF) is an is aerated and agitated system, which gives continuous oxygen flux to the fermentation medium thereby increasing the yield of biomass and cellulose synthesized. In this study, a mathematical model for the synthesis of BC in a RBF system was developed. The growth ...

AU - de Gooijer, K.D.. AU - van den Heuvel, J.C.. PY - 2000. Y1 - 2000. N2 - The static fermentation of coconut water sucrose by Acetobacter xylinum was carried out at initial pHs of 3.0, 4.0, 5.0 or 6.0. Cellulose was produced at the surface, and its production was most favourable at pHs 4.0 and 5.0. These pH values also allowed for optimal bacterial growth. Oxygen concentration profiles were measured with microelectrodes at different cultivation stages, and steep profiles were obtained with penetration depths between 50 and 100 m. A substrate penetration depth analysis confirmed the hypothesis that the first stage of the fermentation is entirely oxygen controlled. Diffusion calculations showed, however, that at a later stage sucrose becomes a limiting substrate also, which was confirmed by the decrease in ...
acetobacter xylinum growth rate?
Then, one could inoculate the medium, distribute the culture into a series of tubes, grow cells in the tubes and withdraw one tube at a time to spin the cells down to determine wet or dry cell weight. For that the empty tubes should be pre-weight beforehand of course. I would suggest drying the cells with acetone by gradual increase of volume percentage from 50 to 75 and finally 100% (2 or three times), drying the tubes at 60C overnight and weighing them shortly after they cool down.

Glycosylated Triterpenoid Saponin: a Specific Inhibitor of Diguanylate Cyclase from Acetobacter xylinum. Biological Activity...
In a recent paper (Ohana et al. 1998), we described the purification and structural characterization of a novel glycosidic triterpenoid saponin (GTS), a specific inhibitor of diguanylate cyclase (dgc), the key regulatory enzyme of the cellulose synthesizing apparatus of the bacterium Acetobacter xylinum. This compound and an identical or very similar one were isolated from pea (Pisum sativum), and A. xylinum respectively. We now present the effects of GTS on the kinetic properties of dgc. The observed inhibition is non-competitive with respect to the substrate GTP, is decreased by 50% in the presence of 20 μM c-di-GMP, and is not observed in the presence of various detergents. Photo-affinity labeling studies using [32P]c-di-GMP and purified enzyme showed that the inhibitor affects binding of c-di-GMP to dgc. It was ascertained that GTS, or at least a very similar compound, is present in other plant systems. The antibiotic Papulacandin B also inhibits dgc, although less efficiently than GTS (Ki ...

SYNTHESIS OF CELLULOSE BY ACETOBACTER XYLINUM | JCB
The transfer of the glucosyl moiety from uridine diphosphate glucose in the presence of Acetobacter xylinum cell-free extracts led to the formation of a mixture of alkali-soluble and -insoluble cellodextrins. Typical cellulose fibrils could not be detected by electron microscopy in this product. Immediately after release into the medium, cellulose formed by whole cells is in a prefibrous form which passes through Millipore filters of 0.45 and 0.8 µ pore diameter. Non-filtrable fibrils arise from this material probably by a process of crystallization involving no extracellular enzymes. Fibrils formed in shaken cell suspensions intertwine and form aggregates visible to the naked eye. In quiet suspensions pellicles are formed which float on the surface. Soluble Na-carboxymethylcellulose (CMC) is incorporated into cellulose fibrils formed in its presence, probably by a process of co-crystallization. Aggregation of fibrils containing CMC is delayed because of electrostatic repulsion between ...

158. Saxena, I. M., Kudlicka, K., Okuda, K., and R. M. Brown, Jr. 1994. Characterization of genes in the cellulose synthesizing operon (acs operon) of Acetobacter xylinum: Implications for cellulose crystallization. J. Bacteriology 176: 5735-5752. 158. Abstract The synthesis of an extracellular ribbon of cellulose in the bacterium Acetobacter xylinum takes place from linearly arranged, membrane-localized, cellulose-synthesizing and extrusion complexes that direct the coupled steps of polymerization and crystallization. To identify the different components involved in this process, we isolated an Acetobacter cellulose-synthesizing (acs) operon from this bacterium. Analysis of DNA sequence shows the presence of three genes in the acs operon, in which the first gene (acsAB) codes for a polypeptide with a molecular mass of 168 M)a, which was identified as the cellulose synthase. A single base change in the previously reported DNA sequence of this gene, resulting in a frameshift and synthesis of a ...
Isolation of Acetic Acid Bacteria and Preparation of Starter Culture for Apple Cider Vinegar Fermentation
Vinegars are commonly used as food condiments and preservatives. Apple cider vinegar (ACV) is also used in the Ayurvedic pharmaceutical industry because of its medicinal properties. Since specifically selected starter cultures for commercial vinegar production are not readily available, apple juice supplemented with sugar is commonly inoculated with a microbiologically undefined culture obtained from the previous batch of ACV. The present work focuses on the isolation of yeasts and acetic acid bacteria from ACV and the preparation of a starter culture. ACV was produced in a bench scale bioreactor using a traditional fermentation process wherein an acetic acid concentration of 3.8% was obtained after three weeks. Several acetic acid bacteria (AAB) were isolated from ACV using selective media. Microscopy revealed the cultures to be gram negative to gram variable short rods. The growth pattern of the isolates on differential media and biochemical tests suggested the presence of Acetobacter and
Enhanced ethanol formation by Clostridium thermocellum via pyruvate decarboxylase | Microbial Cell Factories | Full Text
Pyruvate decarboxylase (PDC) is a well-known pathway for ethanol production, but has not been demonstrated for high titer ethanol production at temperatures above 50 °C. Here we examined the thermostability of eight PDCs. The purified bacterial enzymes retained 20% of activity after incubation for 30 min at 55 °C. Expression of these PDC genes, except the one from Zymomonas mobilis, improved ethanol production by Clostridium thermocellum. Ethanol production was further improved by expression of the heterologous alcohol dehydrogenase gene adhA from Thermoanaerobacterium saccharolyticum. The best PDC enzyme was from Acetobactor pasteurianus. A strain of C. thermocellum expressing the pdc gene from A. pasteurianus and the adhA gene from T. saccharolyticum was able to produce 21.3 g/L ethanol from 60 g/L cellulose, which is 70% of the theoretical maximum yield.

Another Reason to Avoid High-Fat Diet: It Can Disrupt Our Biological Clock - MindSpa
December 31, 2008. Science Daily/Hebrew University of Jerusalem. Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms - everyones 24-hour biological clock, Hebrew University of Jerusalem researchers have shown.. The biological clock regulates the expression and/or activity of enzymes and hormones involved in metabolism, and disturbance of the clock can lead to such phenomena as hormone imbalance, obesity, psychological and sleep disorders and cancer.. While light is the strongest factor affecting the circadian clock, Dr. Oren Froy and his colleagues of the Institute of Biochemistry, Food Science and Nutrition at the Hebrew Universitys Robert H. Smith Faculty of Agriculture, Food and Environment in Rehovot, have demonstrated in their experiments with laboratory mice that there is a cause-and-effect relation between diet and biological clock imbalance..

what is vinegar made of chemically
There are two main elaboration processes to produce vinegar, as follows: (1) traditional methods encompassing the transformation of ethanol into acetic acid by static surface culture of acetic acid bacteria placed at the interface between the liquid and air; and (2) submerged culture methods involving the use of bioreactors with a continuous air flow, thus the conversion of alcohol into acetic acid is much faster and takes place in the air-liquid interfaces of the air bubbles. Early records from China, the Middle East, and Greece describe vinegar for medicinal purposes: as a digestive aid, an antibacterial balm to dress wounds, and treatment for cough. Upon opening, vinegar may start to develop a sort of slime called mother of vinegar that consists of acetic acid bacteria and cellulose. Although acetic acid bacteria are feared among oenologists because they spoil wine, they are the main agents in the production of vinegar. However, some of these ABM can be aged for more than three years and ...
