USING STREPTOMYCES XYLANASE TO PRODUCE XYLOOLIGOSACHARIDE FROM CORNCOB

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011
Streptomyces 234P-16 and SKK1-8 are xylanase-producing bacteria. Corncob xylan were extracted using acidified method. Crude enzymes (produced by centrifuging the culture) were used to hydrolyze xylan from 2 varieties of corncob. Crude extract activity

Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...
