Despite emerging contaminants (ECs) are more and monitored in environmental matrices, there is still a lack of data marine ecosystems, especially on their fate degradation potentials. In this work, for the first time, potential synthetic musks (galaxolide tonalide), UV filters (padimate O octocrylene) pharmaceutical compound (carbamazepine) was studied sediment samples, under laboratory conditi...

R-(-)-2-(3(prm1)-Benzoylphenyl)propionic acid [R-(-)-ketoprofen] was produced from racemic 2-(3(prm1)-benzoylphenyl)propionamide (keto-amide) by the isolated bacterial strain Comamonas acidovorans KPO-2771-4. Sodium fumarate as the carbon source and 2-azacyclononanone or isobutyronitrile as the enhancer in the culture medium were effective for bacterial growth and the enhancement of R-(-)-ketop...

Pseudomonas sp. strain ADP contains the genes, atzA, -B, and -C, that encode three enzymes which metabolize atrazine to cyanuric acid. Atrazine-catabolizing pure cultures isolated from around the world contain genes homologous to atzA, -B, and -C. The present study was conducted to determine whether the same genes are present in an atrazine-catabolizing bacterial consortium and how the genes an...

abstract        typing of bacteria is an important part of epidemiological studies on nosocomial infections. bacterial identification methods have dramatically improved in recent years, which is mainly due to advancements in the field of molecular biotechnology. in many cases, molecular techniques have replaced phenotypic typing methods. currently, a wide range of bacterial typing techniques is...

OBJECTIVE To compare bacterial growth in pure colostrum versus colostrum with human milk fortifier (HMF) containing iron. METHODS The growth of Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa in 78 samples of pure colostrum or colostrum with added iron-containing HMF was compared. For qualitative analysis, filter paper discs were immersed in samples from each group and inc...

the effect of different carbon sources on bacterial cellulose production by gluconacetobacter xylinus (ptcc 1734) and two newly isolated strains (from vinegar) under static culture conditions was studied. the production of bacterial cellulose was examined in modified hestrin-shramm medium by replacing d-glucose with other carbon sources. the results showed that the yield and characteristics of ...

activities of thirty bacterial strains obtained from plants rhizosphere in different areas against phytophthora drechsleri were assessed through in vitro and greenhouse experiments. dual culture and extracellular metabolites tests were used in in vitro assays. the bacterial strains inhibited growth of p. drechsleri, the highest inhibition zones was belonged to t17-4 strain with 61.904% in dual ...

Spiribacter is the most abundant bacterial genus in intermediate-salinity zones of hypersaline environments. However, strains are extremely difficult to isolate pure culture. Therefore, characteristics, genome features, and adaption mechanisms that allow thrive highly saline conditions largely unknown. Here, we show predominant brines from marine solar salterns sulfate-type salt lakes with inte...
