    Isolation and purification of cellulase from alkaline-tolerant Bacillus subtilis 

    Passanee Thongthawee; Malinee Sriariyanun; Kraipat Cheenkachorn; Jirapa Phetsom; Patchanee Yasurin (Universitas Katolik Soegijapranata, 2014-09)

    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 ...

    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 ...

    Screening and primary identification of lipid degradation microorganism from local bioextracts 

    Viyada Kunathigan (2014)

    Bioextract is a solution of fermented organic matters which mainly are agricultural leftover containing living microorganisms. Studies have shown that bioextract may be applied to agriculture, livestock, gardening and landscaping, composting, and bioremediation. Latterly, bioextract was introduced for wastewater treatment, due to bioextract characteristic and environmentally friendly. From previous studies (Nitsuwat et al., 2013), addition of bioextract was capable to reduce total solid, grease and oil in domestic wastewater. The grease and oil ...

    A study of feasibility of pretreatment process to utilize lignocellulosic biomass as materials for biodiesel production 

    Malinee Sriariyanun; Patchanee Yasurin; Jirapa Phetsom (The International Academic Forum, 2013)

    Biomass is the most abundant renewable resource in the world and has potential to use as alternative materials to fossil resources for production of chemicals and fuels. For the effective conversion from biomass to biofuels or other chemicals, it requires high efficient hydrolysis of cellulose to glucose or fermentable sugars. In this study, lignocellulosic biomass, rice straw, rice husk, and water hyacinth were pretreated with different chemicals, or pretreated with microwave heating, or with combination of chemicals and microwave ...

    A study of feasibility to utilize lignocellulosic biomass as materials for biodiesel production 

    Patchanee Yasurin (The International Academic Forum, 2013)

    Lignocellulosic biomass is a renewable, inexpensive, and abundant resource with high potential for biofuel production to implement the sustainable energy energy worldwide. The bottleneck of biofuel production is the recalcitration of ligoncellulosic biomass to fermentable sugars. Searching for a novel cellulase, a biocatalyst is one of major challenges to promote biofuel production with economic and environmental friendly. Natural microorganism is the great source of cellulase production. Therefore the objective of this research is to identify ...
