omega-Amino acid:pyruvate transaminase from Alcaligenes denitrificans Y2k-2: a new catalyst for kinetic resolution of beta-amino acids and amines. (1/44)

Alcaligenes denitrificans Y2k-2 was obtained by selective enrichment followed by screening from soil samples, which showed omega-amino acid:pyruvate transaminase activity, to kinetically resolve aliphatic beta-amino acid, and the corresponding structural gene (aptA) was cloned. The gene was functionally expressed in Escherichia coli BL21 by using an isopropyl-beta-D-thiogalactopyranoside (IPTG)-inducible pET expression system (9.6 U/mg), and the recombinant AptA was purified to show a specific activity of 77.2 U/mg for L-beta-amino-n-butyric acid (L-beta-ABA). The enzyme converts various beta-amino acids and amines to the corresponding beta-keto acids and ketones by using pyruvate as an amine acceptor. The apparent K(m) and V(max) for L-beta-ABA were 56 mM and 500 U/mg, respectively, in the presence of 10 mM pyruvate. In the presence of 10 mM L-beta-ABA, the apparent K(m) and V(max) for pyruvate were 11 mM and 370 U/mg, respectively. The enzyme exhibits high stereoselectivity (E > 80) in the kinetic resolution of 50 mM D,L-beta-ABA, producing optically pure D-beta-ABA (99% enantiomeric excess) with 53% conversion.  (+info)

Pacemaker lead endocarditis caused by Achromobacter xylosoxidans. (2/44)

We report the case of a 35-yr-old patient who presented with high fever and chills. He had undergone a patch closure of the ventricular septal defect 18 yr before. One year later, a VVI pacemaker was implanted via the right subclavian vein because of complete heart block. Nine years after that, a new VVI pacemaker with another right ventricular electrode was inserted controlaterally and the old pacing lead was abandoned. Trans-thoracic and trans-esophageal echocardiogram identified the pacemaker lead in the right ventricle (RV) attaching hyperechoic materials and also a fluttering round hyperechoic mass with a stalk in the RV outflow tract. Cultures in blood and pus from pacemaker lead grew Achromobacter xylosoxidans. A diagnosis of pacemaker lead endocarditis due to Achromobacter xylosoxidans was made. In this regards, the best treatment is an immediate removal of the entire pacing system and antimicrobial therapy.  (+info)

Cloning, overexpression, and characterization of a novel thermostable penicillin G acylase from Achromobacter xylosoxidans: probing the molecular basis for its high thermostability. (3/44)

The gene encoding a novel penicillin G acylase (PGA), designated pgaW, was cloned from Achromobacter xylosoxidans and overexpressed in Escherichia coli. The pgaW gene contains an open reading frame of 2586 nucleotides. The deduced protein sequence encoded by pgaW has about 50% amino acid identity to several well-characterized PGAs, including those of Providencia rettgeri, Kluyvera cryocrescens, and Escherichia coli. Biochemical studies showed that the optimal temperature for this novel PGA (PGA650) activity is greater than 60 degrees C and its half-life of inactivation at 55 degrees C is four times longer than that of another previously reported thermostable PGA from Alcaligenes faecalis (R. M. D. Verhaert, A. M. Riemens, J. V. R. Laan, J. V. Duin, and W. J. Quax, Appl. Environ. Microbiol. 63:3412-3418, 1997). To our knowledge, this is the most thermostable PGA ever characterized. To explore the molecular basis of the higher thermostability of PGA650, homology structural modeling and amino acid composition analyses were performed. The results suggested that the increased number of buried ion pair networks, lower N and Q contents, excessive arginine residues, and remarkably high content of proline residues in the structure of PGA650 could contribute to its high thermostability. The unique characteristic of higher thermostability of this novel PGA provides some advantages for its potential application in industry.  (+info)

Structure-based engineering of Alcaligenes xylosoxidans copper-containing nitrite reductase enhances intermolecular electron transfer reaction with pseudoazurin. (4/44)

The intermolecular electron transfer from Achromobacter cycloclastes pseudoazurin (AcPAZ) to wild-type and mutant Alcaligenes xylosoxidans nitrite reductases (AxNIRs) was investigated using steady-state kinetics and electrochemical methods. The affinity and the electron transfer reaction constant (k(ET)) are considerably lower between AcPAZ and AxNIR (K(m) = 1.34 mM and k(ET) = 0.87 x 10(5) M(-1) s(-1)) than between AcPAZ and its cognate nitrite reductase (AcNIR) (K(m) = 20 microM and k(ET) = 7.3 x 10(5) M(-1) s(-1)). A negatively charged hydrophobic patch, comprising seven acidic residues around the type 1 copper site in AcNIR, is the site of protein-protein interaction with a positively charged hydrophobic patch on AcPAZ. In AxNIR, four of the negatively charged residues (Glu-112, Glu-133, Glu-195, and Asp-199) are conserved at the corresponding positions of AcNIR, whereas the other three residues are not acidic amino acids but neutral amino acids (Ala-83, Ala-191, and Gly-198). Seven mutant AxNIRs with additional negatively charged residues surrounding the hydrophobic patch of AxNIR (A83D, A191E, G198E, A83D/A191E, A93D/G198E, A191E/G198E, and A83D/A191E/G198E) were prepared to enhance the specificity of the electron transport reaction between AcPAZ and AxNIR. The k(ET) values of these mutants become progressively larger as the number of mutated residues increases. The K(m) and k(ET) values of A83D/A191E/G198E (K(m) = 88 microM and k(ET) = 4.1 x 10(5) M(-1) s(-1)) are 15-fold smaller and 4.7-fold larger than those of wild-type AxNIR, respectively. These results suggest that the introduction of negatively charged residues into the docking surface of AxNIR facilitates both the formation of electron transport complex and the electron transfer reaction.  (+info)

The completely sequenced plasmid pEST4011 contains a novel IncP1 backbone and a catabolic transposon harboring tfd genes for 2,4-dichlorophenoxyacetic acid degradation. (5/44)

The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D)-degrading bacterium Achromobacter xylosoxidans subsp. denitrificans strain EST4002 contains plasmid pEST4011. This plasmid ensures its host a stable 2,4-D(+) phenotype. We determined the complete 76,958-bp nucleotide sequence of pEST4011. This plasmid is a deletion and duplication derivative of pD2M4, the 95-kb highly unstable laboratory ancestor of pEST4011, and was self-generated during different laboratory manipulations performed to increase the stability of the 2,4-D(+) phenotype of the original strain, strain D2M4(pD2M4). The 47,935-bp catabolic region of pEST4011 forms a transposon-like structure with identical copies of the hybrid insertion element IS1071::IS1471 at the two ends. The catabolic regions of pEST4011 and pJP4, the best-studied 2,4-D-degradative plasmid, both contain homologous, tfd-like genes for complete 2,4-D degradation, but they have little sequence similarity other than that. The backbone genes of pEST4011 are most similar to the corresponding genes of broad-host-range self-transmissible IncP1 plasmids. The backbones of the other three IncP1 catabolic plasmids that have been sequenced (the 2,4-D-degradative plasmid pJP4, the haloacetate-catabolic plasmid pUO1, and the atrazine-catabolic plasmid pADP-1) are nearly identical to the backbone of R751, the archetype plasmid of the IncP1 beta subgroup. We show that despite the overall similarity in plasmid organization, the pEST4011 backbone is sufficiently different (51 to 86% amino acid sequence identity between individual backbone genes) from the backbones of members of the three IncP1 subgroups (the alpha, beta, and gamma subgroups) that it belongs to a new IncP1subgroup, the delta subgroup. This conclusion was also supported by a phylogenetic analysis of the trfA2, korA, and traG gene products of different IncP1 plasmids.  (+info)

Pitfalls of polymyxin antimicrobial susceptibility testing of Pseudomonas aeruginosa isolated from cystic fibrosis patients. (6/44)

OBJECTIVES AND METHODS: With their potent activity against Gram-negative bacteria, the polymyxins are important alternative antibiotics for cystic fibrosis (CF) patients. A retrospective evaluation of polymyxin activity against 6001 Pseudomonas aeruginosa, 150 Achromobacter xylosoxidans and 506 Stenotrophomonas maltophilia CF isolates was initiated. In addition, we looked at how polymyxin susceptibility testing was affected by the testing method (agar dilution versus microdilution), the agent (polymyxin E versus polymyxin B), incubation time (24 h versus 48 h) and by different interpretative criteria (German DIN, French FSM, British BSAC). RESULTS: Polymyxin B exhibited reasonable activity against P. aeruginosa (MIC(90)< or =2 mg/L), whereas it was less active against A. xylosoxidans (MIC(90)< or =16 mg/L) and S. maltophilia (MIC(90)< or =16 mg/L). During 2000-2002, polymyxin B resistance in P. aeruginosa, S. maltophilia and A. xylosoxidans was found to be 6.7%, 17.0% and 29.9% (corresponding to 12.4%, 20.7% and 35.4% of infected patients), respectively. When the agar dilution method was used, polymyxin E exhibited higher MICs than polymyxin B. The microdilution method produced lower polymyxin MICs than the agar dilution method. Therefore, the microdilution MICs after prolonged incubation (48 h) and the agar dilution MICs of polymyxin B correlated best (AUC of 0.93, r(2) of 0.44 and s of 0.83). CONCLUSIONS: Polymyxin resistance among common CF pathogens is not rare, thus underlining the necessity of accurate susceptibility testing. When compared with the agar dilution method, it was found that the microdilution method is a valid, rapid and cost effective alternative for the determination of polymyxin activity. The performance of the microdilution method was most reliable after prolonged incubation (48 h) at a susceptibility breakpoint of < or =4 mg/L according to the BSAC guidelines (specificity 91%, sensitivity 89%, 1.5% very major errors).  (+info)

Cyclo(L-leucyl-L-prolyl) produced by Achromobacter xylosoxidans inhibits aflatoxin production by Aspergillus parasiticus. (7/44)

Aflatoxins are potent carcinogenic and toxic substances that are produced primarily by Aspergillus flavus and Aspergillus parasiticus. We found that a bacterium remarkably inhibited production of norsolorinic acid, a precursor of aflatoxin, by A. parasiticus. This bacterium was identified as Achromobacter xylosoxidans based on its 16S ribosomal DNA sequence and was designated A. xylosoxidans NFRI-A1. A. xylosoxidans strains commonly showed similar inhibition. The inhibitory substance(s) was excreted into the medium and was stable after heat, acid, or alkaline treatment. Although the bacterium appeared to produce several inhibitory substances, we finally succeeded in purifying a major inhibitory substance from the culture medium using Diaion HP20 column chromatography, thin-layer chromatography, and high-performance liquid chromatography. The purified inhibitory substance was identified as cyclo(L-leucyl-L-prolyl) based on physicochemical methods. The 50% inhibitory concentration for aflatoxin production by A. parasiticus SYS-4 (= NRRL2999) was 0.20 mg ml(-1), as determined by the tip culture method. High concentrations (more than 6.0 mg ml(-1)) of cyclo(L-leucyl-L-prolyl) further inhibited fungal growth. Similar inhibitory activities were observed with cyclo(D-leucyl-D-prolyl) and cyclo(L-valyl-L-prolyl), whereas cyclo(D-prolyl-L-leucyl) and cyclo(L-prolyl-D-leucyl) showed weaker activities. Reverse transcription-PCR analyses showed that cyclo(L-leucyl-L-prolyl) repressed transcription of the aflatoxin-related genes aflR, hexB, pksL1, and dmtA. This is the first report of a cyclodipeptide that affects aflatoxin production.  (+info)

Shared Genotypes of Achromobacter xylosoxidans Strains Isolated from Patients at a Cystic Fibrosis Rehabilitation Center: During a study examining transmission
Achromobacter xylosoxidans (formerly Alcaligenes xylosoxidans) is a Gram-negative, aerobic, oxidase and catalase-positive, motile bacterium with peritrichous flagella, from the genus Achromobacter. It is generally found in wet environments. Achromobacter xylosoxidans can cause infections such as bacteremia, especially in patients with cystic fibrosis. In 2013, the complete genome of an A. xylosoxidans strain from a patient with cystic fibrosis was sequenced. A. xylosoxidans is a Gram-negative rod that does not form spores. It is motile, with peritrichous flagella that distinguish it from Pseudomonas species, and is oxidase-positive, catalase-positive, and citrate-positive. It is urease and indole-negative. It produces acid oxidatively from xylose, but not from lactose, maltose, mannitol, or sucrose. It grows well on MacConkey agar and other inhibitory growth media such as deoxycholate, Salmonella-Shigella, and nalidixic acid-cetrimide agars. It is usually resistant to a variety of antibiotics ...
TY - JOUR. T1 - Gene cloning and characteristics of the RND-type multidrug efflux pump MuxABC-OpmB possessing two RND components in Pseudomonas aeruginosa. AU - Mima, Takehiko. AU - Kohira, Naoki. AU - Li, Yang. AU - Sekiya, Hiroshi. AU - Ogawa, Wakano. AU - Kuroda, Teruo. AU - Tsuchiya, Tomofusa. PY - 2009. Y1 - 2009. N2 - muxA-muxB-muxC-opmB (formerly PA2528-PA2527-PA2526-opmB), encoding a putative resistance nodulation cell division (RND)-type multidrug efflux pump system, was cloned from Pseudomonas aeruginosa PAO1. Introduction of muxABC-opmB into P. aeruginosa YM64, a drug-hypersusceptible strain, led to elevated MICs of aztreonam, macrolides, novobiocin and tetracycline. Since muxB and muxC, both of which encode RND components, were essential for function, MuxABC-OpmB is thought to be a drug efflux pump with four components. One novobiocin-resistant mutant, PMX725, isolated from P. aeruginosa PMX7 showed elevated resistance not only to novobiocin but also to aztreonam, macrolides and ...
Introduction: Achromobacter xylosoxidans is a water‐borne organism that causes healthcare‐associated infections and has been isolated from blood, cerebrospinal fluid, stool, urine, sputum, peritoneal fluid, skin, ear discharge, wounds, abscesses, bone, joints, endocardium and central venous catheters, mostly in immunocompromised patients. Case presentation: We describe here the rare case of a young immunocompetent alcoholic male admitted with symptoms of acute pancreatitis who failed to improve with conventional management. Blood culture later showed the growth of A. xylosoxidans. The patient improved when he was treated with antibiotics as per the sensitivity report. Conclusion: Although Achromobacter is rarely isolated from clinical samples, it should never be assumed to be a contaminant as this infection has propensity for progression to fatal bacteraemia, even in apparently healthy individuals.
In Pseudomonas aeruginosa, quorum sensing (QS) regulates the production of secondary metabolites, many of which are antimicrobials that impact on polymicrobial community composition. Consequently, quenching QS modulates the environmental impact of P. aeruginosa. To identify bacteria capable of inactivating the QS signal molecule 2-heptyl-3- hydroxy-4(1H)-quinolone (PQS), a minimal medium containing PQS as the sole carbon source was used to enrich a Malaysian rainforest soil sample. This yielded an Achromobacter xylosoxidans strain (Q19) that inactivated PQS, yielding a new fluorescent compound (I-PQS) confirmed as PQS-derived using deuterated PQS. The I-PQS structure was elucidated using mass spectrometry and nuclear magnetic resonance spectroscopy as 2-heptyl-2-hydroxy-1,2-dihydroquinoline- 3,4-dione (HHQD). Achromobacter xylosoxidans Q19 oxidized PQS congeners with alkyl chains ranging from C1 to C5 and also N-methyl PQS, yielding the corresponding 2-hydroxy-1,2-dihydroquinoline-3,4- diones, ...
This large outbreak (N = 12) of A. xylosoxidans bloodstream infections was caused by 1 strain, which was also isolated from CVC biofilm. Symptoms of bloodstream infection probably occurred when flushes detached bacteria from the CVC biofilm. The prospective study found that 3 (10%) of 29 patients had A. xylosoxidans-positive blood cultures. Our case-control and prospective studies support the association of A. xylosoxidans bloodstream infection and CVCs, and our molecular biologic studies confirm A. xylosoxidans biofilm of the same outbreak strain on a CVC. A. xylosoxidans outbreaks reported to date have been associated with healthcare and contamination of hospital products (1,2,5,12-14), but none occurred in an outpatient setting.. The cause of this outbreak most likely was the use of contaminated multidose vials of heparin or saline flushes, leading to the formation of an A. xylosoxidans biofilm on CVCs. Case-patient 1 had been hospitalized from late October through early November at Hospital ...
Seasonal variations are often observed for respiratory tract infections; however, limited information is available regarding seasonal patterns of acquisition of common cystic fibrosis (CF)-related respiratory pathogens. We previously reported differential seasonal acquisition of Pseudomonas aeruginosa in young children with CF and no such variation for methicillin-susceptible Staphylococcus aureus acquisition. The purpose of this study was to describe and compare the seasonal incidence of acquisition of other respiratory bacterial pathogens in young children with CF. We conducted a retrospective study to describe and compare the seasonal incidence of methicillin-resistant Staphylococcus aureus (MRSA), Stenotrophomonas maltophilia, Achromobacter xylosoxidans, and Haemophilus influenzae acquisition in young CF patients residing in the U.S. using the Cystic Fibrosis Foundation National Patient Registry, 2003-2009. Log-linear overdispersed Poisson regression was used to evaluate seasonal acquisition of each
Amoebae feed on bacteria, and few bacteria can resist their microbicidal ability. Amoebal coculture could therefore be used to selectively grow these amoebae-resisting bacteria (ARB), which may be human pathogens. To isolate new ARB, we performed amoebal coculture from 444 nasal samples. We recovered 7 (1.6%) ARB from 444 nasal swabs, including 4 new species provisionally named Candidatus Roseomonas massiliae, C. Rhizobium massiliae, C. Chryseobacterium massiliae, and C. Amoebinatus massiliae. The remaining isolates were closely related to Methylobacterium extorquens, Bosea vestrii, and Achromobacter xylosoxidans. Thus, amoebal coculture allows the recovery of new bacterial species from heavily contaminated samples and might be a valuable approach for the recovery of as-yet unrecognized emerging pathogens from clinical specimens.

Achromobacter spp. are recognized as emerging pathogens in hospitalized as well as in cystic fibrosis (CF) patients. From 2012 to 2015, we collected 69 clinical isolates (41 patient) of Achromobacter spp. from 13 patients with CF (CF isolates, n = 32) and 28 patients receiving care for other health conditions (non-CF isolates, n = 37). Molecular epidemiology and virulence potential of isolates were examined. Antimicrobial susceptibility, motility, ability to form biofilms and binding affinity to mucin, collagen, and fibronectin were tested to assess their virulence traits. The nrdA gene sequencing showed that A. xylosoxidans was the most prevalent species in both CF and non-CF patients. CF patients were also colonized with A. dolens/A, ruhlandii, A. insuavis, and A. spiritinus strains while non-CF group was somewhat less heterogenous, although A. insuavis, A. insolitus, and A. piechaudii strains were detected beside A. xylosoxidans. Three strains displayed clonal distribution, one amon...g ...
In this study, in order to construct a model of leftover bath water, we analyzed one hundred samples of used bath water samples which were provided by twenty-eight volunteer families. It appeared that the number of detected bacteria from such bath water was correlated closely with the number of bathers. Moreover, the pH, acidity, chemical oxygen demand (COD), ion, protein content of the leftover bath water were measured. The number of bathers had no connection with the pH, acidity, COD, and ion content of the leftover bath water. However, the protein content of the bath water correlated with the number of detected bacteria. Based on these results, the model of leftover bath water was constructed. ,I,Achromobacter xylosoxidans, Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa,/I, were incubated with the model bath wateras indices of bath water contamination. The number of incubated viable cells in the model bath water increased ...
Factitious fever is extremely challenging to diagnose in patients with complicated chronic medical problems, and represents as much as 10% of fevers of unknown origin. Factitious fever caused by self-injecting oral medications through indwelling central catheters is a diagnostic challenge. We present a 32-year-old Caucasian female with history of short gut syndrome, malnutrition requiring total parental nutrition, and pancreatic auto-islet transplant with fever of unknown origin. Multiple episodes of bacteremia occurred with atypical pathogens, including α-hemolytic Streptococcus, Achromobacter xylosoxidans, and Mycobacterium mucogenicum. Chest computed tomography was notable for extensive tree-in-bud infiltrates. Sudden cardiac arrest with right-sided heart failure following acute hypoxemia led to her death. Diffuse microcrystalline cellulose emboli with foreign body granulomatosis was found on autopsy. Circumstantial evidence indicated that this patient suffered from factitious disorder, and was self

Achromobacter species derived from the sputa of CF patients are garnering increasing attention. Indeed, improvements in diagnostic techniques enabling the correct distinction of these species from other CF pathogens, such as P. aeruginosa, and selective antimicrobial pressures may have contributed to their initial recognition (19, 23), although their rates did not appear to be changing over the last decade (7). Our study is the first to report epidemiological and clinical outcome data for CF patients infected with Achromobacter species in a North American cohort.. The cumulative prevalence of Achromobacter isolation of 11% in our center is comparable to those previously reported for small centers, which ranged from 5 to 29% (11, 12), although this spans 3 decades, making the incidence of infection very low. While others have reported that older patients and patients with greater lung disease burden appear to be predisposed to infection with Achromobacter species (11, 18), we did not observe any ...
Achromobacter sp. AO22 (formerly Alcaligenes sp. AO22), a bacterial strain isolated from a lead-contaminated industrial site in Australia, was previously found to be resistant to moderate to high levels of mercury, copper and other heavy metals. However, the nature and location of the genetic basis for mercuric ion resistance in this strain, had not been previously identified. Achromobacter sp. AO22 contains a functional mer operon with all four essential genes (merRTPA) and shows |99% DNA sequence identity to that of Tn501. The mer operon was present on a transposon, designated TnAO22, captured by introducing a broad-host-range IncP plasmid into Achromobacter sp. AO22 and subsequently transferring it to E. coli recipients. The transposition frequency of TnAO22 was 10-2 to 10-3 per target plasmid transferred. Analysis of TnAO22 sequence revealed it belonged to the Tn21 subgroup of the Tn3 superfamily of transposons, with the transposition module having |99% identity with Tn5051 of a Pseudomonas putida
Background Preoperative coronary angiography (CA) is recommended in patients with acute aortic valve infective endocarditis (AV-IE) and high cardiovascular risk profile but the level of evidence is low and its potential interest may be counterbalanced by the risk of dislodgement of vegetations and contrast-induced nephropathy.. Objective To review the use, indications and complication of preoperative CA in patients with AV-IE.. Design Retrospective study.. Patients Consecutive series of 83 patients operated on for AV-IE between January 2002 and March 2007.. Results CA was performed in 36 (43%) patients, all but one as a preoperative test. Significant (≥70%) lesions were observed in 10 patients and six underwent an associated coronary artery bypass graft. 47 patients were operated on without preoperative CA because of young age in 16 or recent CA in 13. Despite being theoretically indicated in all but one of the 18 remaining patients, CA was not performed because surgery as judged too urgent ...

Bacteria capable of degrading polymeric products were isolated from several sources including tap water, sediment, and a deteriorated polymeric product. Alcaligenes xylosoxidans; T2, Pseudomonas aeruginosa GP10, and Nocardia corynebacterioides S3 were able to utilize rubber products as a sole source of carbon and energy. These microorganisms showed different growth patterns in mineral salt media (MSM) supplemented with rubber strips or with the rubber extract. A. xylosoxidans T2, P. aeruginosa GP10 and N. corynebacterioides S3 reduced the weight of the rubber product by approximately 2.0, 4.0 and 5.3%, respectively, after 70 days of incubation with the rubber product in MSM. On average, 0.45 mg (water-soluble carbon) g(-1) of the rubber product was released into solution phase after 7 days of incubation. Growth of N. corynebacterloides S3 was initially slower but exceeded the other two bacteria upon colonization of the polymer products. N. corynebacterioides S3 formed a dense biofilm on surfaces ...

Bacteria of the Achromobacter genus, more particularly xylosoxidans species, are responsible for various healthcare associated infections (HAI) which are increasingly described since the last decade. Cystic fibrosis (CF) patients are considered as potential reservoirs in hospitals. We performed a retrospective study to estimate the frequencies of Achromobacter spp. HAI among patients from French West Indies, to determine characteristics of infected patients and establish a possible link between CF and infections. All adults with at least one Achromobacter spp. positive sample and infection criteria in accordance with European official definitions of HAI, hospitalized in University Hospital of Martinique from 2006 to 2016 for more than 48 h, were included. Patient clinical features, immune status and underlying diseases were obtained from medical files. A list of CF patients was given by clinicians. Antibiotic-susceptibility profiles of the strains were determined using an automated method. Mean
Achromobacter bacteria seen in chronic CF lung infections showed patient-to-patient transmission and emerging antibiotic resistance in study.

This parameter is a very useful tool that involves the degradation rate and the biomass growth, referred to the initial biomass instead of the actual biomass. Progressively, the biomass grows and the degradation rate increases. This parameter simultaneously takes both into account.. Results and discussion. The mixed culture constituted of Pseudomonas aeruginosa and Achromobacter marplatensis was able to simultaneously degrade the mixture of highly-substituted chlorophenols PCP, 2,3,5,6-TeCP and 2,4,6-TCP, as the only source of carbon and energy in batch and fed-batch systems. The initial experimental settings for the fed-batch assays at different feed flow rates (I, II, III) and the batch system control (B) is shown in Table 1. The initial biomass was similar in all cases but the initial CP concentrations were much higher in B than in the fed-batch assays when they were close to zero (Table I). The substrate to biomass yield coefficients based on total CP degradation are also shown in Table 1. ...

In an effort to engineer plants to be resistant to glyphosate, scientists starting looking for glyphosate resistant EPSP in the 1980s. Several methods were employed including selection, directed evolution, site-directed mutagenesis, and microbial screens. It was difficult to obtain a suitable enzyme because typically the resistant enzymes had an undesirable decrease in catalytic activity. Eventually, naturally occurring glyphosate-tolerant microbes were identified including Agrobacterium sp. Strain CP4, Achromobacter sp. Strain LBAA, and Pseudomonas sp. Strain PG2982. The enzymes isolate from these maintained good catalyctic ativity while being resistant to glyphosate (Funke). Agrobacterium sp. Strain CP4 was obtained from a glyphosate rich waste area at a glyphosate production facility. There is substantial sequence variation between these resistant enzymes and those of plants or E. coli. Other versions resistant versions of EPSP have been identified in Streptococcus pneumonia and ...
The early stages of degradation of native collagen by two bacterial collagenases were studied by electron microscopy and by automatic Edman degradation. The purified collagenase from Clostridium histolyticum was shown to cleave native collagen at several sites, but not progressively from the N-terminus, as had been previously suggested. The homogeneous collagenase from Achromobacter iophagus cleaves native collagen preferentially at two sites corresponding to the interbands 33-34 and 41-42. The latter lies within the region cleaved by the eukaryotic collagenases. ...
