Crude extracts were prepared using the solvent ethanol from the seaweeds viz., Gracilaria edulis, Calorpha peltada and Hydroclothres sp. and screening for their antibacterial activity against six bacterial pathogens were also carried out. The test bacterial strains were Escherichia coli, Enterobacter aerogenes, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus faecalis and Bacillus c...
Pseudomonas sp. strain ADP initiates atrazine catabolism via three enzymatic steps, encoded by atzA, -B, and -C, which yield cyanuric acid, a nitrogen source for many bacteria. In-well lysis, Southern hybridization, and plasmid transfer studies indicated that the atzA, -B, and -C genes are localized on a 96-kb self-transmissible plasmid, pADP-1, in Pseudomonas sp. strain ADP. High-performance l...
Isolation of lignin degrading microorganisms from cow dung, soil compost, and paper pulp effluent was carried out in the present investigation. Totally 9 isolates of lignin degrading microbes were isolated using minimal salt media containing lignin (MSM-L) and lignolytic activities were preliminary screened by testing against methylene blue indicator dye containing LB medium. Eight microbes sho...
A bacterium, Pseudomonas sp. strain C1S1, able to grow on 2,4,6-trinitrotoluene (TNT), 2,4- and 2,6-dinitrotoluene, and 2-nitrotoluene as N sources, was isolated. The bacterium grew at 30 degrees C with fructose as a C source and accumulated nitrite. Through batch culture enrichment, we isolated a derivative strain, called Pseudomonas sp. clone A, which grew faster on TNT and did not accumulate...
Actinopyga lecanora, a type of sea cucumber commonly known as stone fish with relatively high protein content, was explored as raw material for bioactive peptides production. Six proteolytic enzymes, namely alcalase, papain, pepsin, trypsin, bromelain and flavourzyme were used to hydrolyze A. lecanora at different times and their respective degrees of hydrolysis (DH) were calculated. Subsequent...
Identification of novel transaminases from a 12-aminododecanoic acid-metabolizing Pseudomonas strain
A Pseudomonas species [Pseudomonas sp. strain amino alkanoate catabolism (AAC)] was identified that has the capacity to use 12-aminododecanoic acid, the constituent building block of homo-nylon-12, as a sole nitrogen source. Growth of Pseudomonas sp. strain AAC could also be supported using a range of additional ω-amino alkanoates. This metabolic function was shown to be most probably dependent...
Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...
در این تحقیق اثر کاربرد سیلیکون و باکتری (Pseudomonas fluorescens (CHAO روی بیماری پژمردگی فوزاریومی گوجه فرنگی ناشی از قارچ Fusarium oxysporum f. sp. lycopersiciو القای مقاومت میزبان در مقابل پاتوژن مورد بررسی قرار گرفت. اثر غلظتهای مختلف سیلیکون ( 7-1 میلی مولار) بر رشد Pseudomonas fluorescens و Fusarium oxysporum f. sp. lycopersici آزمایش شد. نتایج نشان داد که همه غلظتهای سیلیکون روی رشد ب...
Pseudomonas sp. MX-058 produces aldehyde oxidase catalysing glyoxal to glyoxylic acid. Two aldehyde oxidases (F10 and F13) were purified to homogeneity from Pseudomonas sp. MX-058. F10 and F13 had subunit structures, a heterotetramer and heteropentamer respectively. The N-terminal amino acid sequences of all subunits were highly homologous to amino acid sequences of the putative oxidoreductases...
Molecular evolution analysis of 16S rRNA sequences of native Pseudomonas strains and different fluorescent pseudomonads were conducted on the basis of Molecular Evolutionary Genetics Analysis version 5.2 (MEGA5.2). Topological evaluations show common origin for native strains with other known strains with available sequences at GenBank database. Phylogenetic affiliation of different Pseudomonas...
