Carbon Source-Dependent Regulation
The Zymomonas mobilis gene encoding phosphoglucose isomerase (pgi) was cloned by genetic complementation of an Escherichia coli pgi mutant. An enzyme assay and sodium dodecyl sulfate-polyacrylamide gel electrophoresis confirmed the presence of excess amounts of phosphoglucose isomerase in E. coli clones carrying the Z. mobilis pgi gene. The pgi gene is present in only one copy on the Z. mobilis...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولRegulation by carbon source of enzyme expression and slime production in bacterium W3A1.
Slime production by bacterium W3A1 was greatly enhanced during growth on methanol and, to a lesser extent, during growth on trimethylamine. Of the major dehydrogenases synthesized, trimethylamine and methylamine dehydrogenases were induced to different levels by certain carbon sources, while methanol dehydrogenase was expressed during growth on all carbon sources.
متن کاملChapter 4. Analyzing the regulation of antibiotic production in streptomycetes.
This chapter outlines the approaches and techniques that can be used to analyze the regulation of antibiotic production in streptomycetes. It describes how to isolate antibiotic nonproducing and overproducing mutants by UV, nitrosoguanidine (NTG), transposon, and insertion mutagenesis, and then how to use those mutants to identify regulatory genes. Other approaches to identify both pathway-spec...
متن کاملProduction of Clavulanic Acid by Streptomyces clavuligerus in Batch Cultures with Using Wheat Bran as the Source of Carbon
Nowadays Microbial biotechnology is considered as one of the most important and profitable branches of industry. In this approach, by using the generator microorganisms, We are able to produce biotechnological products, with higher efficiency. Clavulanic acid is being used in combination with commonly used beta-lactam antibiotics in order to fight against bacterial infections that are resistant...
