Retting and degumming of natural fibers by pectinolytic enzymes produced from Bacillus tequilensis SV11-UV37 using solid state fermentation.

The present study demonstrated the simultaneous production and optimization of pectinolytic enzymes (pectate lyase and polygalacturonase) under SSF from Bacillus tequilensis SV11-UV37 using wheat bran as a substrate, which is commercially viable and cost-effective. Optimization by one variable-at-a-time-approach showed a maximum yield of pectate lyase (1371.25 U/gds) and polygalacturonase (85.

A novel thermostable, alkaline pectate lyase from Bacillus tequilensis SV11 with potential in textile industry.

An extracellular pectate lyase was purified and characterized from a UV mutant of Bacillus tequilensis SV11. Purification resulted in a 16.2-fold improvement in the enzyme specific activity, with approximately 40.

Effect of chemical and microbial vitamin B₁₂ analogues on production of vitamin B₁₂.

Strain improvement by genetic manipulation or optimization of fermentation conditions for overproduction of vitamin B(12) has a drawback due to feed back inhibition. To resist the feed back inhibition by analogues of vitamin B(12) in Propionibacterium freudenrechii subsps. shermanii (OLP-5), we have tested with microbially separated B(12) analogues from three different strains.
