In this study, a novel betaproteobacterium, strain DPN7(T), was isolated under mesophilic conditions from compost because of its capacity to utilize the organic disulfide 3,3'-dithiodipropionic acid. Analysis of the 16S rRNA gene sequence of strain DPN7(T) revealed 98.5 % similarity to that of Tetrathiobacter kashmirensis LMG 22695(T). Values for sequence similarity to members of the genera Alc...

Oil contamination in Iran due to high application of oil compounds, is one of the most dangerous pollution factors. Bioremediation is one of principal strategies for remediation, where in the pollutants can be removed by use of microorganism or any biological process that uses microorganisms or their enzymes to return the environment altered by contaminants to its original condition. With regar...

Indole is widely spread in various environmental matrices. Indole degradation by bacteria has been reported previously, whereas its degradation processes driven by aerobic microbial community were as-yet unexplored. Herein, eight sequencing batch bioreactors fed with municipal and coking activated sludges were constructed for aerobic treatment of indole. The whole operation processes contained ...

A technological system was developed for efficient nitrogen removal from real digester supernatant in a single reactor with shortened aeration to increase the economical aspects of wastewater treatment. The supernatant (600 mg TKN/L, low COD/N ratio of 2.2) was treated in batch reactors with aerobic granules (GSBRs) to test how one, two, or three non-aeration phases and acetate pulse feeding in...

This study evaluated the ability of the Rapid NFT system (API System SA, Montalieu-Vercieu, France) to accurately identify 262 clinically isolated, gram-negative, nonfermentative rods without additional tests. Identifications were classified as correct; low discrimination, with a spectrum of two or more possibilities (additional tests necessary for accurate identification); and incorrect. Corre...

The recombinant Pseudomonas putida strain CB1-9, which acquired the ability to grow on chlorobenzenes, contains a 33-kilobase (kb) plasmid (pKFL3) which lacked homology to an indigenous 15-kb plasmid (pKFL1) in Pseudomonas alcaligenes C-0 parent but was homologous to a 55-kb plasmid (pKFL2) from the P. putida R5-3 parent. Chromosomal DNA of P. alcaligenes C-0 hybridized to probes prepared from ...

In this study, a screening of the efficacy microbial consortium bacteria and fungi isolated from activated sludge, river sediment, compost for degradation LDPE/TPS was performed. According to morphological biochemical characterization, eight bacteria, Bacillus sonorensis, subtilis, Lysinibacillus massiliensis, licheniformis, indicus, megaterium, cereus, Pseudomonas alcaligenes, five molds, Aspe...
