Bioprocessing of bagasse hydrolysate for ethanol and xylitol production using thermotolerant yeast.

Fermentation of xylose-rich and glucose-rich bagasse hydrolysates, obtained from the two-stage acid hydrolysis was studied using the thermotolerant yeast Kluyveromyces sp. IIPE453. The yeast could grow on xylose-rich hydrolysate at 50 °C with the dry cell weight, cell mass yield and maximum specific growth rate of 5.

A novel thermostable xylanase of Paenibacillus macerans IIPSP3 isolated from the termite gut.

Xylanase is an enzyme in high demand for various industrial applications, such as those in the biofuel and pulp and paper fields. In this study, xylanase-producing microbes were isolated from the gut of the wood-feeding termite at 50°C. The isolated microbe produced thermostable xylanase that was active over a broad range of temperatures (40-90°C) and pH (3.

Characterization of hyperthermostable alpha-amylase from Geobacillus sp. IIPTN.

A newly isolated Geobacillus sp. IIPTN (MTCC 5319) from the hot spring of Uttarakhand's Himalayan region produced a hyperthermostable alpha-amylase. The microorganism was characterized by biochemical tests and 16S rRNA gene sequencing.
