Characterization of a two-component alkanesulfonate monooxygenase from Escherichia coli. (1/165)

The Escherichia coli ssuEADCB gene cluster is required for the utilization of alkanesulfonates as sulfur sources, and is expressed under conditions of sulfate or cysteine starvation. The SsuD and SsuE proteins were overexpressed and characterized. SsuE was purified to homogeneity as an N-terminal histidine-tagged fusion protein. Native SsuE was a homodimeric enzyme of M(r) 58,400, which catalyzed an NAD(P)H-dependent reduction of FMN, but it was also able to reduce FAD or riboflavin. The SsuD protein was purified to >98% purity using cation exchange, anion exchange, and hydrophobic interaction chromatography. The pure enzyme catalyzed the conversion of pentanesulfonic acid to sulfite and pentaldehyde and was able to desulfonate a wide range of sulfonated substrates including C-2 to C-10 unsubstituted linear alkanesulfonates, substituted ethanesulfonic acids and sulfonated buffers. SsuD catalysis was absolutely dependent on FMNH(2) and oxygen, and was maximal for SsuE/SsuD molar ratios of 2.1 to 4.2 in 10 mM Tris-HCl, pH 9.1. Native SsuD was a homotetrameric enzyme of M(r) 181,000. These results demonstrate that SsuD is a broad range FMNH(2)-dependent monooxygenase catalyzing the oxygenolytic conversion of alkanesulfonates to sulfite and the corresponding aldehydes. SsuE is the FMN reducing enzyme providing SsuD with FMNH(2).  (+info)

The Escherichia coli ssuEADCB gene cluster is required for the utilization of sulfur from aliphatic sulfonates and is regulated by the transcriptional activator Cbl. (2/165)

The growth properties of an Escherichia coli strain carrying a chromosomal deletion of the ssuEADCB genes (formerly designated ycbPONME) indicated that the products of this gene cluster are required for the utilization of sulfur from aliphatic sulfonates. Sequence similarity searches indicated that the proteins encoded by ssuA, ssuB, and ssuC are likely to constitute an ABC type transport system, whereas ssuD and ssuE encode an FMNH(2)-dependent monooxygenase and an NAD(P)H-dependent FMN reductase, respectively (Eichhorn, E., van der Ploeg, J. R., and Leisinger, T. (1999) J. Biol. Chem. 274, 26639-26646). Synthesis of beta-galactosidase from a transcriptional chromosomal ssuE'-lacZ fusion was repressed by sulfate or cystine and depended on the presence of a functional cbl gene, which encodes a LysR-type transcriptional regulator. Electrophoretic mobility shift assays with the ssu promoter region and measurements of beta-galactosidase from plasmid-encoded ssuE'-'lacZ fusions showed that full expression of the ssu operon required the presence of a Cbl-binding site upstream of the -35 region. CysB, the LysR transcriptional regulator for the cys genes, was not required for expression of a chromosomal ssuE'-lacZ fusion although the ssu promoter region contained three CysB-binding sites. Integration host factor could also occupy three binding sites in the ssu promoter region but had no influence on expression of a chromosomal ssuE'-lacZ fusion.  (+info)

Deletion analysis of the Escherichia coli taurine and alkanesulfonate transport systems. (3/165)

The Escherichia coli tauABCD and ssuEADCB gene clusters are required for the utilization of taurine and alkanesulfonates as sulfur sources and are expressed only under conditions of sulfate or cysteine starvation. tauD and ssuD encode an alpha-ketoglutarate-dependent taurine dioxygenase and a reduced flavin mononucleotide-dependent alkanesulfonate monooxygenase, respectively. These enzymes are responsible for the desulfonation of taurine and alkanesulfonates. The amino acid sequences of SsuABC and TauABC exhibit similarity to those of components of the ATP-binding cassette transporter superfamily, suggesting that two uptake systems for alkanesulfonates are present in E. coli. Chromosomally located in-frame deletions of the tauABC and ssuABC genes were constructed in E. coli strain EC1250, and the growth properties of the mutants were studied to investigate the requirement for the TauABC and SsuABC proteins for growth on alkanesulfonates as sulfur sources. Complementation analysis of in-frame deletion mutants confirmed that the growth phenotypes obtained were the result of the in-frame deletions constructed. The range of substrates transported by these two uptake systems was largely reflected in the substrate specificities of the TauD and SsuD desulfonation systems. However, certain known substrates of TauD were transported exclusively by the SsuABC system. Mutants in which only formation of hybrid transporters was possible were unable to grow with sulfonates, indicating that the individual components of the two transport systems were not functionally exchangeable. The TauABCD and SsuEADCB systems involved in alkanesulfonate uptake and desulfonation thus are complementary to each other at the levels of both transport and desulfonation.  (+info)

Ethane sulfonate metabolite of alachlor: assessment of oncogenic potential based on metabolic and mechanistic considerations. (4/165)

Chronic administration of alachlor has been shown to produce neoplastic responses in the nasal turbinate mucosa, glandular stomach mucosa, and thyroid follicular epithelium of rats. Subsequent studies have shown that specific metabolic activation of alachlor is required for nasal tumor formation, and that non-genotoxic, threshold-sensitive processes produce all three tumors. The herbicide alachlor is degraded in the soil by microbial action to the tertiary ethane sulfonate metabolite (ESA). The acute and subchronic toxicity of ESA is very low, and the metabolite did not produce developmental toxicity or genotoxicity. The studies described here were conducted to determine whether ESA shares a common mechanism of oncogenicity with alachlor in rats. Specifically, we studied ESA's pharmacokinetics and ability to produce changes that are causally associated with the oncogenicity of alachlor. These studies demonstrated that ESA was poorly absorbed and underwent minor metabolism, which contrasted with the significant absorption and substantial metabolism observed with alachlor. ESA was also excreted more quickly than alachlor and showed no evidence of accumulation in the nasal turbinates, a site of oncogenicity for alachlor in the rat. In addition, ESA did not elicit the characteristic preneoplastic changes observed in the development of alachlor-induced nasal, stomach, and thyroid tumors. The results of these studies support the conclusion that ESA does not share a common oncogenic mechanism with alachlor and would not be expected to produce the same oncogenic responses observed following chronic alachlor exposure in rats.  (+info)

Characterization of a sulfur-regulated oxygenative alkylsulfatase from Pseudomonas putida S-313. (5/165)

The atsK gene of Pseudomonas putida S-313 was required for growth with alkyl sulfate esters as sulfur source. The AtsK protein was overexpressed in Escherichia coli and purified to homogeneity. Sequence analysis revealed that AtsK was closely related to E. coli taurine dioxygenase (38% amino acid identity). The AtsK protein catalyzed the alpha-ketoglutarate-dependent cleavage of a range of alkyl sulfate esters, with chain lengths ranging from C(4) to C(12), required oxygen and Fe(2+) for activity and released succinate, sulfate, and the corresponding aldehyde as products. Enzyme activity was optimal at pH 7 and was strongly stimulated by ascorbate. Unlike most other characterized alpha-ketoglutarate-dependent dioxygenases, AtsK accepted a range of alpha-keto acids as co-substrates, including alpha-ketoglutarate (K(m) 140 microm), alpha-ketoadipate, alpha-ketovalerate, and alpha-ketooctanoate. The measured K(m) values for hexyl sulfate and SDS were 40 and 34 microm, respectively. The apparent M(r) of the purified enzyme of 121,000 was consistent with a homotetrameric structure, which is unusual for this enzyme superfamily, members of which are usually monomeric or dimeric. The properties and amino acid sequence of the AtsK enzyme thus define it as an unusual oxygenolytic alkylsulfatase and a novel member of the alpha-ketoglutarate-dependent dioxygenase family.  (+info)

In vitro activity of a novel antimycobacterial compound, N-octanesulfonylacetamide, and its effects on lipid and mycolic acid synthesis. (6/165)

beta-Sulfonyl carboxamides have been proposed to serve as transition-state analogues of the beta-ketoacyl synthase reaction involved in fatty acid elongation. We tested the efficacy of N-octanesulfonylacetamide (OSA) as an inhibitor of fatty acid and mycolic acid biosynthesis in mycobacteria. Using the BACTEC radiometric growth system, we observed that OSA inhibits the growth of several species of slow-growing mycobacteria, including Mycobacterium tuberculosis (H37Rv and clinical isolates), the Mycobacterium avium complex (MAC), Mycobacterium bovis BCG, Mycobacterium kansasii, and others. Nearly all species and strains tested, including isoniazid and multidrug resistant isolates of M. tuberculosis, were susceptible to OSA, with MICs ranging from 6.25 to 12.5 microg/ml. Only three clinical isolates of M. tuberculosis (CSU93, OT2724, and 401296), MAC, and Mycobacterium paratuberculosis required an OSA MIC higher than 25.0 microg/ml. Rapid-growing mycobacterial species, such as Mycobacterium smegmatis, Mycobacterium fortuitum, and others, were not susceptible at concentrations of up to 100 microg/ml. A 2-dimensional thin-layer chromatography system showed that OSA treatment resulted in a significant decrease in all species of mycolic acids present in BCG. In contrast, mycolic acids in M. smegmatis were relatively unaffected following exposure to OSA. Other lipids, including polar and nonpolar extractable classes, were unchanged following exposure to OSA in both BCG and M. smegmatis. Transmission electron microscopy of OSA-treated BCG cells revealed a disruption in cell wall synthesis and incomplete septum formation. Our results indicate that OSA inhibits the growth of several species of mycobacteria, including both isoniazid-resistant and multidrug resistant strains of M. tuberculosis. This inhibition may be the result of OSA-mediated effects on mycolic acid synthesis in slow-growing mycobacteria or inhibition via an undescribed mechanism. Our results indicate that OSA may serve as a promising lead compound for future antituberculous drug development.  (+info)

Short-chain aliphatic polysulfonates inhibit the entry of Plasmodium into red blood cells. (7/165)

Several steps in the pathogenesis of a Plasmodium falciparum infection depend on interactions of parasite surface proteins with negatively charged sugars on the surface of host cells such as sialate residues or glycosaminoglycans. For these reasons, our previous studies examining agents that interfere with heparan sulfate-protein binding during amyloidogenesis suggested that short-chain aliphatic polysulfonates may prove useful as antimalarial agents. A series of related polysulfonates were synthesized and assessed both in tissue culture with the asexual stages of P. falciparum in human red blood cells and in vivo by use of Plasmodium berghei infections in mice. Poly(vinylsulfonate sodium salt) (molecular weight range, 1,500 to 3,000) proved effective in interfering with P. falciparum merozoite entry into human red blood cells and significantly delaying the increase in the level of P. berghei parasitemia in mice. The concept that anionic molecules that mimic large polysaccharide structures may have antimalarial properties has been suggested and examined previously. Our results suggest that related anionic agents [poly(vinylsulfonate sodium salt)-like molecules] orders of magnitude smaller than those previously considered may prove useful in abrogating merozoite entry into erythrocytes and may potentially block sporozoite entry into liver cells. Structure-activity studies conducted to enhance these properties may provide compounds with scope for significant further analysis and development.  (+info)

AZ 242, a novel PPARalpha/gamma agonist with beneficial effects on insulin resistance and carbohydrate and lipid metabolism in ob/ob mice and obese Zucker rats. (8/165)

Abnormalities in fatty acid (FA) metabolism underlie the development of insulin resistance and alterations in glucose metabolism, features characteristic of the metabolic syndrome and type 2 diabetes that can result in an increased risk of cardiovascular disease. We present pharmacodynamic effects of AZ 242, a novel peroxisome proliferator activated receptor (PPAR)alpha/gamma agonist. AZ 242 dose-dependently reduced the hypertriglyceridemia, hyperinsulinemia, and hyperglycemia of ob/ob diabetic mice. Euglycemic hyperinsulinemic clamp studies showed that treatment with AZ 242 (1 micromol/kg/d) restored insulin sensitivity of obese Zucker rats and decreased insulin secretion. In vitro, in reporter gene assays, AZ 242 activated human PPARalpha and PPARgamma with EC(50) in the micro molar range. It also induced differentiation in 3T3-L1 cells, an established PPARgamma effect, and caused up-regulation of liver fatty acid binding protein in HepG-2 cells, a PPARalpha-mediated effect. PPARalpha-mediated effects of AZ 242 in vivo were documented by induction of hepatic cytochrome P 450-4A in mice. The results indicate that the dual PPARalpha/gamma agonism of AZ 242 reduces insulin resistance and has beneficial effects on FA and glucose metabolism. This effect profile could provide a suitable therapeutic approach to the treatment of type 2 diabetes, metabolic syndrome, and associated vascular risk factors.  (+info)

The S1 secondary alkylsulphohydrolase of the detergent-degrading micro-organism, Pseudomonas C12B, was separated from other alkylsulphohydrolases and purified to homogeneity. Under the experimental conditions used the enzyme completely hydrolysed d-octan-2-yl sulphate (d-1-methylheptyl sulphate), but showed no activity towards the corresponding l-isomer. Additional evidence has been obtained to indicate that it is probably optically stereospecific for d-secondary alkyl sulphate esters with the ester sulphate group at C-2 and with a chain length of at least seven carbon atoms. Enzyme activity towards racemic samples of heptan-2-yl sulphate (1-methylhexyl sulphate), octan-2-yl sulphate and decan-2-yl sulphate (1-methylnonyl sulphate) increased with increasing chain length. l-Octan-2-yl sulphate is a competitive inhibitor of the enzyme, as are certain primary alkyl sulphates and primary alkanesulphonates. Inhibition by each of the last two types of compounds is characteristic of the behaviour of an ...
Improvement of insulin sensitivity and lipid and glucose metabolism by coactivation of both nuclear peroxisome proliferator-activated receptor (PPAR)gamma and PPARalpha potentially provides beneficial effects over existing PPARgamma and alpha preferential drugs, respectively, in treatment of type 2 diabetes. We examined the effects of the dual PPARalpha/gamma agonist ragaglitazar on hyperglycemia and whole body insulin sensitivity in early and late diabetes stages in Zucker diabetic fatty (ZDF) rats and compared them with treatment with the PPARgamma preferential agonist rosiglitazone. Despite normalization of hyperglycemia and Hb A(1c) and reduction of plasma triglycerides by both compounds in both prevention and early intervention studies, ragaglitazar treatment resulted in overall reduced circulating insulin and improved insulin sensitivity to a greater extent than after treatment with rosiglitazone. In late-intervention therapy, ragaglitazar reduced Hb A(1c) by 2.3% compared with 1.1% by

The analogs showed a different behavior toward cells with acquired resistance against the normal product disorazole C1 , which owe their resistance phenotype at the least in part to overexpression in the ABCB1 p glycoprotein pump. All agents have been subnanomolar inhibitors of wild kind HeLa cells. Paclitaxel and vinblastine had been 1395 and 502 fold much less active, respectively, during the resistant cells . Knockdown of the Pglycoprotein pump, ABCB1, restored most, of their activity . In contrast, the HeLa DZR cells showed only small cross resistance to the dictyostatin analogs that was thoroughly reversed by ABCB1 knockdown. The information propose that the dictyostatins may perhaps be only weak substrates for ABCB1. Additionally, as the HeLa DZR cells have been generated by just one exposure on the mutagen ethyl methane sulfonate followed by a stepwise improved disorazole C1 exposure, its possible that resistance mechanisms apart from elevated ABCB1 exist, but these never seem to ...
The clip The facts of life from Blade Runner (1982) with Joe Turkel, Rutger Hauer The facts of life. To make an alteration in the evolvement of an organic life system is fatal. A coding sequence cannot be revised once its been established. Why not? Because by the second day of incubation any cells that have undergone reversion mutations give rise to revertant colonies like rats leaving a sinking ship. Then the ship sinks. What about EMS recombination? Weve already tried it. Ethyl methane sulfonate is an alkylating agent and a potent mutagen. It created a virus so lethal the subject was dead before he left the table. Then a repressor protein that blocks the operating cells. Wouldnt obstruct replication, but it does give rise to an error in replication. So that the newly formed DNA strand carries a mutation and youve got a virus again. But this, all of this, is academic. You were made as well as we could make you. But not to last. The light that burns twice as bright burns half as long. And you have

The collected data of the present and previous studies [6, 7, 15, 16, 24] allows to build a model of the regulation of sulphur metabolism in C. glutamicum (Fig. 7). Almost all genes known to be involved in sulphur metabolism are negatively controlled by the global transcriptional repressor McbR. McbR is in turn negatively controlled by SAH which is thought to link sulphur metabolism to cell growth (reviewed in [2]). With an increasing SAH pool, transcription of the genes under McbR control is derepressed, resulting in the increased expression of the genes needed to synthesise the sulphur-containing amino acids. In addition, the two ROK-type regulators CysR and SsuR are expressed, providing the basis for the subsequent regulatory cascade. The prerequisite to trigger the next step of the cascade is the accumulation of either OAS or OAH which are needed for CysR-mediated gene regulation. Both act as acceptor molecules for sulphide leading to L-cysteine and L-homocysteine in sulphydrylase-catalysed ...

0036] Ethyl tricosa-1,22-diene-12-sulfonate). In a flame dried 3-necked flask equipped with a magnetic stir bar, 2.5 mL (20 mmol, 1 eq) of ethyl methane sulfonate and 4.4 mL (20 mmol, 1 eq) of 11-bromoundecene were stirred in 20 mL of dry THF under argon. After bringing the solution to -78° C., 0.9 eq of LDA was added dropwise over 30 minutes and stirred for 30 additional minutes. The solution was then warmed to 0° C. and stirred for 1 to 2 hours until mono-alkylation was observed and alkenyl bromide disappeared by TLC. After bringing the solution back to -78° C., 0.9 eq of 11-bromoundecene was added slowly and allowed to dissolve. With the solution at -78° C., 0.9 eq of LDA was added dropwise over 30 minutes and stirred for 30 additional minutes. The solution was then warmed to 0° C. and stirred for 2 to 3 hours until the conversion from mono-alkylation to diene product was no longer observed. The reaction was quenched by adding ice cold water. This mixture was then extracted (3 ×50 mL) ...
Dont drink the water. Thats what people from Flint, Mich., to a little New York town called Hoosick Falls have been hearing.. In Flint, its lead. We all know what that is. In Hoosick Falls, its perfluorooctanoic acid (PFOA). Never heard of it? Well, its probably in your kitchen or closet, and almost definitely in your body.. PFOA is a type of perfluoroalkyl acid (PFAA), a group of chemicals studied by Laura MacManus-Spencer. And PFAAs are used in everything from Gore-Tex clothing and Duponts StainMaster carpet to non-stick pans and coatings for microwave popcorn bags.. "PFAAs are everywhere in the environment. Every U.S resident has a measurable amount of PFAAs in their blood," she said. "And literally every organism that scientists pluck out of the environment has these chemicals in their blood.". "These chemicals are not known to be very acutely toxic (it wont cause illness immediately), unless youre exposed to really high concentrations," MacManus-Spencer continued. "The concern is ...

Perfluoroalkyl acids (PFAAs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer applications, such as constituents in fire fighting foams, hydraulic oils and food packaging materials.PFAAs have shown to be highly persistent in the environment, and the toxicological potential of long chain PFAA homologues is of a concern. International regulation and voluntary actions by the industry have been implemented and led to reduced primary emissions of PFAAs to the environment. However, the concentrations of some PFAAs in e.g. birds from the Baltic Sea are still very high and of ecotoxicological concern. Measures to reduce the PFAA contamination require an understanding of the sources and how the PFAAs are being transported in the environment.In this licentiate thesis a mass balance was assembled for perfluorohexanoic acid (PFHxA), perfluorooctanoic acid (PFOA), perfluorodecanoic acid (PFDA) and perfluorooctane sulfonic acid (PFOS) in the ...

The effect of processing methods and sugar consentration on the quality of soymilk were investigated. The investigation had been performed using Factorial Completely Randomized Design (CRD) with two factors, i.e. Method of Processing (Ml, M2, M3, M4) and Consentration of Sugar (8%, 10%, 12%, 14%). Parameters analysed were total soluble solid, protein content, fat content, and organoleptic value. The results show that the processing method had highly significant effect on organoleptic value and significant affect on total soluble solid and protein content but not on fat content. The consentration of sugar had highly significant effect on total soluble solid, protein content and organoleptic but only significant effect on fat content. The combination of processing method and sugar consentration had highly significant effect on organoleptic value but had no significant effect on the total soluble solid, protein content and fat content. The third method was the best processesing method and 8% sugar ...

Campylobacter jejuni is now recognised as a major cause of food-borne enteritis. Characteristics of Campylobacter spp. make them less amenable to genetic analysis using standard molecular biology techniques. These problems can prevent the isolation and characterisation of campylobacter loci. In the absence of an efficient method for the generation of random mutations, the only mutagenesis strategy available is that which targets specific genes. The two approaches described were developed specifically for the analysis of specific genes. The polymerase chain reaction (PCR) with degenerate oligonucleotide primers (PCRDOP/inverse PCR mutagenesis (IPCRM)) and inverse PCR strategies are designed to isolate and utilise small regions of DNA for the defined mutagenesis of targeted campylobacter genes. Moreover with the development of the IPCR mutagenesis, a small amount of sequence is the only requirement for the application of this approach. To evaluate the potential of both of these approaches, they ...
Several environmental contaminants, such as polychlorinated biphenyls, dioxins, bisphenol A and phthalates, have been linked to diabetes. We therefore investigated whether other kinds of contaminants, perfluoroalkyl substances (PFAS), also called perfluorinated compounds (PFCs), are also associated with diabetes. The Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study investigated 1,016 men and women aged 70 years. Seven PFAS were detected in almost all participant sera by ultra-high performance liquid chromatograph/tandem mass spectrometry. Diabetes was defined as use of hypoglycaemic agents or fasting glucose , 7.0 mmol/l. 114 people had diabetes. In the linear analysis, no significant relationships were seen between the seven PFAS and prevalent diabetes. However, inclusion of the quadratic terms of the PFAS revealed a significant non-linear relationship between perfluorononanoic acid (PFNA) and diabetes, even after adjusting for multiple confounders (OR 1.96, 95% CI ...

Prior to the implementation of more sophisticated genetic techniques, mutagenesis was often performed using simple chemical mutagens including N-methyl-N-nitro-N-nitroso-guanidine (MMNG) and ethyl methane sulfonate (EMS) . The basic approach involves exposing a population of cells to a controlled dose of mutagen, to generate progeny that carry random genetic mutations The application of this technique has traditionally been limited by two important considerations First, it often proves difficult to strike a balance between efficiency and selectivity; exposure to the mutagen must be carefully controlled in order to maximize the frequency of single mutations Second, it should be noted that chemical mutagenesis is random; the experimenter needs to select or identify mutants of interest from a large pool of random mutants. For more detailed information on the background and procedures involved in chemical mutagenesis, we refer the reader to Miller (1992) The basic protocols that have been described ...

Hi Angie. I think there is the assumption that I have done one of two things - I have said that your SCI contains extra stearic acid and that SCI with extra stearic acid is a bad thing. It isnt a bad thing - it offers extra emollience to a product (which might not be desirable for those of us with oily hair). I have done much searching and I cannot find any reference to your SCI containing extra stearic acid (I know you havent done a search, but I definitely encourage it because I cant find anything but would be happy to alter it if you did!) When I refer to SCI on the blog without specifying the supplier, I am referring to the Jordapon prills I buy from Aquarius. I have your flakes, but I dont use them as often as I do the prills (customer preference and all that). I have also purchased SCI from other suppliers so I could test out versions with extra stearic acid with those that dont contain it. So when I refer to SCI, I am not referring specifically to any products from your shop ...
Alfa Chemistry is the worlds leading provider for special chemicals. We offer qualified products for 114394-36-4(Sodium 1-amine-2-naphthol-4-sulfonate),please inquire us for 114394-36-4(Sodium 1-amine-2-naphthol-4-sulfonate).
Gloeobacter violaceus sp. PCC 7421 is an unusual cyanobacterium with only one cellular membrane, which lacks the thylakoid membranes found in other oxygenic photosynthetic organisms. The cell membrane lipids in G. violaceus sp. PCC 7421 are monogalactosyl diacylglycerol, digalactosyl diacylglycerol, phosphatidyl glycerol and phosphatidic acid in the molar proportion of 51, 24, 18 and 4% respectively. This lipid composition resembles that of the cell membrane from other cyanobacteria, but completely lacks sulfoquinovosyl diacylglycerol. This lack of sulfoquinovosyl diacylglycerol is exceptional for a photosynthetic membrane. The membrane lipids are esterified to 14:0, 16:0, 16:1, 18:0, 18:1, 18:2 and alpha 18:3 fatty acids.. ...
Hydrolysis of cellulose to glucose is the most critical step in bioconversion of lignocellulosic biomass to fuels and chemicals. Cellulases and homogenous acids are widely used for cellulose hydrolysis. However, cellulases can only be used at moderate conditions and need longer time to achieve satisfactory cellulose hydrolysis. Homogenous acids can tolerate higher temperature, but they have limitations and issues such as equipment corrosion, recycling and wastewater treatment. To address these issues, heterogeneous solid acids have recently drawn a lot of attention for hydrolyzing cellulose. Traditional solid acids such as sulfonated carbon and resins, however, are not as effective as homogenous acids and cellulases in hydrolyzing cellulose because they have poor access/affinity to cellulose. In this study, a series of porous polymeric solid acids were synthesized for cellulose hydrolysis. These cellulase-mimetic solid acids have hydroxyl, halide, or boronic acid as cellulose-binding group in ...

Memilih kondom yang baik penting agar manfaat dan hasilnya optimal. Kondom saat ini digunakan sebagai alat kontrasepsi, mengurangi risiko tertular penyakit menular seks, dan membantu mengatasi masalah gangguan seks tertentu. Misalnya, ejakulasi dini.. Untuk tujuan kontrasepsi, faktor kondisi, kualitas, dan cara pemakaian kondom memegang peran penting agar tidak menyebabkan kehamilan. Kegagalan saat ini terjadi disebabkan pemakaian kondom dilakukan tidak teratur, kadang pakai dan kadang tidak. Bila hubungan seks dilakukan saat istri subur, antara lain karena tanggal masa subur berubah, lepas kondom meningkatkan risiko hamil.. Dalam memilih kondom untuk tujuan kontrasepsi, pilih yang berbahan lateks karena tidak mudah sobek/rusak dibandingkan yang berbahan poliuretan. Secara umum, kondom yang beredar di Indonesia sudah memenuhi syarat standar mutu internasional (ISO). Namun, konsumen tetap perlu memperhatikan kondisi kondom saat membeli atau ketika mau menggunakan.. Pada kertas bungkus semua ...

Solid acid catalysts were synthesized from macroalgae Sargassum horneri via hydrothermal carbonization followed by sulfuric acid sulfonation. A three-variable Box-Behnken design and optimization was used to maximize surface acidity. The optimal preparation conditions were found to be at the carbonization temperature of 217 °C, the carbonization time of 4.6 hours and the sulfonation temperature of 108.5 °C. Under these conditions, the highest surface acidity achieved was 1.62 mmol g-1. Physical and chemical properties of prepared solid acid catalyst were characterized by powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, and elemental analysis. The results proved the grafting of -SO3H groups on an amorphous carbon structure. The catalyst activity was evaluated by the esterification of oleic acid with methanol. The sample prepared achieved 96.6% esterification yield, which was higher than the 86.7% yield achieved by commercial Ambersyst-15 under the same reaction ...
Dietary intake has been estimated to be the major ongoing pathway of human exposure to perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkane sulfonic acids (PFSAs). However, difficulties associated with the analysis of food samples have hampered the reliable quantification of dietary exposure. Here the dietary exposure of the average Swedish population to PFCAs and PFSAs is estimated through analysis of a range of homologues in representative food basket samples from 1999, 2005 and 2010. Exposure to perfluorooctane sulfonate (796−1424 pg kg. -1day-1), perfluoroundecanoic acid (88−212 pg kg-1day-1), perfluorodecanoic acid (52−102 pg kg-1day-1) and perfluorononanoic acid (62−83 pg kg-1day-1) was dominated by the consumption of fish and meat. In contrast, exposure to perfluorooctanoic acid (322−513 pg kg-1day-1) originated from low levels (8−62 pg g-1) found in several ―high consumption‖ food categories including cereals, dairy products, vegetables and fruit. The average body ...

The occurrence and effects of ubiquitously present persistent organic pollutants (POPs) in the environment is one of the challenges the society is facing today. Two categories of chemicals that have gained increased public attention during the last decades are organic flame retardants (FRs) and perfluoroalkyl substances (PFASs). Many representatives from these compound groups have bioaccumulative, persistent and toxic properties. This has led to a ban of some of these compounds based on international agreements.. FRs and PFASs end up in surface waters and sometimes also in ground water due to their widespread distribution, disinclination of getting removed at wastewater treatment plants (WWTPs), and persistence. However, the knowledge of the occurrence, fate, and effect in the environment of FRs and PFASs is still in great need of research, especially for recently introduced compounds (such as novel FRs). The objective of this project was to provide a snapshot of the current pollution situation ...
