Eight synthetic and nine biogenetic surfactants were tested on their toxicity. Because of their possible application as oil dispersants against oil slicks on sea, the test organisms used were marine microorganisms (mixed and pure cultures of bacteria, microalgae, and protozoa). Bacterial growth was hardly effected or stimulated, whilst that of algae and flagellates was reduced. All substances t...
The conversion of 2-chloro-cis,cis-muconate by muconate cycloisomerase from Pseudomonas putida PRS2000 yielded two products which by nuclear magnetic resonance spectroscopy were identified as 2-chloro- and 5-chloromuconolactone. High-pressure liquid chromatography analyses showed the same compounds to be formed also by muconate cycloisomerases from Acinetobacter calcoaceticus ADP1 and Pseudomon...
The primary goal of this study was to isolate hydrocarbon-degrading organisms and assess their ability to bioremediate petroleum-contaminated soil and water. Nigeria is one of the major oil producing countries and petroleum contamination is widespread in agricultural soil. Alcaligenes sp. strain 3k was isolated from a kerosene-polluted soil in Ilorin, Nigeria. We also assessed its ability to de...
کاربرد فراوان مواد نفتی در ایران سبب آلودگی بسیاری از زیستگاه‌ها به مواد نفتی شده است. زیست بهسازی و بهره‌گیری از باکتری‌ها در راستای کاهش آلودگیهای نفتی روشی کم هزینه و سازگار با محیط زیست میباشد. از اینرو، غربالگری باکتری‌های تجزیهکننده ترکیب‌های نفتی از نمونههای آلوده به نفت منطقه بوشهر در محیط کشت بدون کربن آلی انجام شد. در این پژوهش، 19 سویه باکتری گرم منفی به نام‌های PDB1-19 از نمو...

The amino acid sequences of haemoglobin-like proteins from the bacteria Alcaligenes eutrophus, Bacillus subtilis, Erwinia chrysanthemi, Escherichia coli, Vibrio parahaemolyticus, Vitreoscilla sp. and the yeast Saccharomyces cerevisiae were studied. Phylogenies based on distance and parsimony analysis showed that the eubacterial group can be easily distinguished from the other haemoglobin-like p...
Biochemistry of civet coffee fermentation in the digestive tract civets until now is not fully known. This study aims to isolation, characterization and identification bacteria molecularly from civet's tract. Analysis begins with surgery obtain fluid three parts Isolation conducted by pour plate method using nutrient agar media. Single different colonies (shape, colour, margin, elevation, size)...
The indigenous bacteria create natural cohabitation niches together with mucosal Abs in the gastrointestinal (GI) tract. Here we report that opportunistic bacteria, largely Alcaligenes species, specifically inhabit host Peyer's patches (PPs) and isolated lymphoid follicles, with the associated preferential induction of antigen-specific mucosal IgA Abs in the GI tract. Alcaligenes were identifie...
The use of the replicator technique in evaluating carbon source utilization by 55 cultures of Alcaligenes faecalis was examined. Six of the 20 substrates tested were utilized by the bacterial cultures. In this study, the reproducibility of the technique was 100%.
