Isolation, Optimization, and Molecular Characterization of a Lipase Producing Bacterium from Oil Contaminated Soils
Lipases have many applications in biotechnology, thanks to their ability of acylglycerides hydrolysis. They alsp possess the unique feature of acting at the lipid-water interface, which distinguishes them from esterases. Commercially useful lipases are produced by microorganisms with the extracellular lipase being produced by many bacteria including Pseudomonas. The greatest production of lipas...

متن کاملIsolation and characterization of the recA gene of Rhizobium meliloti.
Interspecific complementation of an Escherichia coli recA mutant with plasmids containing a gene bank of Rhizobium meliloti DNA was used to identify a clone which contains the recA gene of R. meliloti. The R. meliloti recA protein can function in recombination and in response to DNA damage when expressed in an E. coli recA host, and hybridization studies have shown that DNA sequence homology ex...
متن کاملبررسی مقاومت به شوری در گونه Sesbania aculeata
شوری یکی از مهمترین عوامل کاهش محصولات کشاورزی و رستنی‌های طبیعی در بسیاری از مناطق دنیا ازجمله ایران است. سسبانیا آکیولاتا از تیره بقولات گیاهی علوفه‌ای خوشخوراک و نسبتاً مقاوم به شوری است که می‌تواند برای احیای مراتع لب‌شور بکار برده شود. این پژوهش به منظور ارزیابی سطوح مقاومت به شوری این گیاه با تکیه بر انباشتگی یون‌ها و تغییرات تشریحی انجام شده است. بدین منظور بذر سسبانیا در محیط کشت شنی ...
متن کاملNicotinic acid requirement and degradation by Sesbania rhizobium strain ORS571
Sevhtrriia rliizobiuni strain ORS57 1. which grows in the free-living state at the expense of N, or ammonia. requires nicotinic acid as a growth factor and also uses this vitamin as a nitrogen source in culture medium devoid of ammonia. Consequently, under nitrogen-fixing conditions, Sesbania rhizohiw1 requires about 10-times more nicotinic acid than when grown in the presence of ammonia. The p...
