Currently, the ability to convert raw materials from lignocellulose-rich biomass by traditional methods has many limitations. Therefore, the objective of the thesis is to exploit a variety of biocatalysts (hydrolases) from fungi to efficiently convert lignocellulose-rich biomass from ABP into sugars (C5 and C6) capable of fermenting for bioethanol production. The thesis uses "enzyme cocktail" synergistic catalyst to increase the ability of biological transformation.

The research objective of the thesis is to select microorganisms capable of producing laccase, laccaselike from Ba Vi National Forest area, in herbicide / dioxin contaminated soil at Bien Hoa airport. Assessing the ability of decomposing herbicides containing dioxin and reactive dyes by laccase, laccase-like and VSV strains were selected to guide the application in defense activities.
