A New Approach to Produce Resveratrol by Enzymatic Bioconversion

Journal of Microbiology and Biotechnology, 2016
An enzymatic reaction system was developed and optimized for bioconversion of resveratrol from glucose. Liquid enzyme extracts were prepared from Alternaria sp. MG1, an endophytic fungus from grape, and used directly or after immobilization with sodium alginate. When the enzyme solution was used, efficient production of resveratrol was found within 120

Bioconversion of cassava bagasse and sugarcane bagasse using cheap home-made enzymatic cocktails [PDF]

, 2021
Abstract The agricultural industries generate lignocellulosic wastes that can be modified by fungi to generate high value-added products. The aim of this work was to analyze the efficiency of the bioconversion of sugarcane bagasse and cassava bagasse using two cheap home-made enzymatic cocktails from Aspergillus niger LBM 134 (produced also ...

Enzymatic Bioconversion of Agave Leaves FiberHydrolysis Using Plackett-Burman Design [PDF]

American Journal of Agricultural and Biological Sciences, 2011
Problem statement: Biofuels production is becoming a key factor to help decrease pollution levels and the dependency of fossil fuels. Cellulose from lignocellulosic biomass is being used as a source of raw material for biofuels production, specifically bioethanol, so many ways to use it for this purpose are being developed.

Investigations into Enzymatic Bioconversion to Form Rebaudioside A from Stevioside

Periodica Polytechnica Chemical Engineering, 2018
Stevia rebaudiana Bertoni is a perennial shrub from South America that produces steviol glycosides which are 200-300 times sweeter than sugar. Stevioside and rebaudioside A are the main sweetening components of its leaves. Steviol glycosides are diterpenoids whose biosynthetic pathways have four steps in common with gibberellic acid formation. The most

Enhanced Bioethanol Production from Industrial Xylose Residue Using Efficient Delignification

BioResources, 2016
Xylose residue (XR), the abundant industrial residue from commercial xylose production, was delignified using alkali as a substrate for ethanol production via simultaneous saccharification and fermentation (SSF). It was found that pretreatment with 1.5% (
