Probing control in B. licheniformis fermentations
In industrial biotechnical processes in fed-batch mode it is desirable to keep a high feed rate in order to achieve a high production rate, while simultaneously avoiding overflow metabolism. This means that the optimum of the process is close to the point where it risks crashing due to the effects of overflow metabolites. Probing control of feed rate is a control strategy for microbial processe...
متن کاملTranscriptional attenuation control of ermK, a macrolide-lincosamide-streptogramin B resistance determinant from Bacillus licheniformis.
ermK instructs bacteria to synthesize an erythromycin-inducible 23S rRNA methylase that confers resistance to the macrolide, lincosamide, and streptogramin B antibiotics. Expression of ermK is regulated by transcriptional attenuation, in contrast to other inducible erm genes, previously described, which are regulated translationally. The ermK mRNA leader sequence has a total length of 357 nucle...

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Purification and Characterization of Azoreductase from B. licheniformis
Dye decolorizing bacteria was isolated and identified from textile effluent samples. The isolate was identified as Bacillus licheniformis by 16S rDNA sequencing. Azoreductase, an enzyme responsible for catalyzing the reductive cleavage of azo bonds was purified from B.licheniformis. The enzyme was purified by a combination of ammonium sulphate precipitation, ion exchange and affinity chromatogr...
متن کاملProbing the molecular determinant for the catalytic efficiency of L-arabinose isomerase from Bacillus licheniformis.
Bacillus licheniformis l-arabinose isomerase (l-AI) is distinguished from other l-AIs by its high degree of substrate specificity for l-arabinose and its high turnover rate. A systematic strategy that included a sequence alignment-based first screening of residues and a homology model-based second screening, followed by site-directed mutagenesis to alter individual screened residues, was used t...
