Around 200 different lipopeptides (LPs) have been identified to date, most of which are produced via Bacillus and Pseudomonas species. The clinical nature of the lipopeptide (LP) has led to a big surge in its research. They show antimicrobial and antitumor activities due to which mass-scale production and purification of LPs are beneficial. Response surface methodology (RSM) approach has emerged as an alternative in the field of computational biology for optimizing the reaction parameters using statistical models. In the present study, Pseudomonas sp.

Thinning supplies of natural resources increase attention to sustainable microbial production of bio-based fuels. The strain Clostridium beijerinckii NRRL B-598 is a relatively well-described butanol producer regarding its genotype and phenotype under various conditions. However, a link between these two levels, lying in the description of the gene regulation mechanisms, is missing for this strain, due to the lack of transcriptomic data.

Bacillus cereus is a notorious foodborne pathogen, which can grow under anoxic conditions. Anoxic growth is supported by endogenous redox metabolism, for which the thiol redox proteome serves as an interface. Here, we studied the cysteine (Cys) proteome dynamics of B. cereus ATCC 14579 cells grown under fermentative anoxic conditions. We used a quantitative thiol trapping method combined with proteomics profiling.

We observed that batch time 25 h, inoculum age 20 h, 8% (v/v) inoculum size, pH 6.5 and temperature 37 °C were found as the most suitable operating conditions for ADI production. Galactose, peptone, KH2PO4 and L-arginine were found as the best carbon, nitrogen, mineral ion and inducer for ADI production, respectively.

Three pectinolytic microbial consortia developed for faster retting of jute (Chorchorus olitorius L. and Chorchorus capsularis L.) were subjected to various pH (4 to 12) and media with variable nitrogen and fixed carbon sources for optimization of fermentation conditions of the consortia for cost-effective pectin degrading enzyme production. All the microbial consortia were active over a wide range of pH from 6 to 10 and recorded maximum polygalacturonase and pectin lyase activities at pH 10.
