    Lignocellulosic biomass is one of the most abundant renewable resource in the world. It has high potential to be used as material for biorefinery process because it yields fermentable sugar that can be converted to various bioproducts via microorganism functions. To make the biorefinery process success, the efficient hydrolysis process is needed to be improved to release the maximum amounts of sugars from lignocellulosic biomass. Natural environment is an important source to find an efficient cellulase producing bacteria. Previously, an ...

    Production, purification and characterization of an ionic liquid tolerant cellulase from Bacillus sp. isolated from rice paddy field soil 

    Patchanee Yasurin (2015)

    Background: Lignocellulosic biomass is a renewable, abundant, and inexpensive resource for biorefining process to produce biofuel and valuable chemicals. To make the process become feasible, it requires the use of both efficient pretreatment and hydrolysis enzymes to generate fermentable sugars. Ionic liquid (IL) pretreatment has been demonstrated to be a promising method to enhance the saccharification of biomass by cellulase enzyme; however, the remaining IL in the hydrolysis buffer strongly inhibits the function of cellulase. This study aimed ...

    Purification and identification of bacterial cellulase activity of Bacillus subtilis W48 for biofuel production 

    Patchanee Yasurin (School of Biotechnology, Assumption University of Thailand, 2014-07)

    Lignocellulosic biomass is a renewable, inexpensive, and abundant resource with high potential for biofuel production to implement the sustainable energy worldwide. An important key of biofuel production is the hydrolysis of lignocellulosic biomass to fermentable sugars. Screening for a novel cellulase, as a biocatalyst, is challenge for development of biofuel production to be the economic and environmental friendly process. Natural environment is an important source to find ...
