Production, concentration and partial characterization of an enzymatic extract produced by an mutant in solid state fermentation.

An enzymatic extract from 3T5B8 was produced by Solid State Fermentation (SSF) in aerated columns, using wheat bran as substrate. A combination of extracts produced using three different process conditions varying temperature, pH and aeration formed the final extract (Mixture). The Mixture was concentrated by an ultrafiltration process that partially purified and provided an efficient recovery of the enzymatic activities of xylanase (88.

Solid-state fermentation production and characterization of an alkaline lipase from a newly isolated strain.

The newly isolated BRM58833 strain was shown to secrete an alkaline lipase highly active and stable in organic solvents. Lipase production was optimized through the cultivation of the strain by solid-state fermentation in wheat bran. The lipase extraction conditions were also optimized.

Silencing of a BAHD acyltransferase in sugarcane increases biomass digestibility.

Background: Sugarcane ( spp.) covers vast areas of land (around 25 million ha worldwide), and its processing is already linked into infrastructure for producing bioethanol in many countries. This makes it an ideal candidate for improving composition of its residues (mostly cell walls), making them more suitable for cellulosic ethanol production.
