BIOCONVERSION OF LIGNOCELLULOSIC BIOMASS TO ETHANOL USING DIFFERENT MICROORGANISMS

Pretreatment of Lignocellulosic Biomass Using Microorganisms: Approaches, Advantages, and Limitations

Ultrasonically Assisted Conversion of Lignocellulosic Biomass to Ethanol

In order to improve the bioconversion of lignocellulosic materials in an environmentally friendly manner, we choose to use the ultrasonic energy. Since enzymatic hydrolysis of cellulose represents a significant part of production costs, it is economically advantageous to develop a technique for reducing the cellulolitic enzyme loading. Thus, the sonication was employed in a two steps concept pr...

Transformation of Starchy Lignocellulosic Biomass to Ethanol using Ragi Tapai Synergized with Microwave Irradiation Pretreatment

Ethanol production strategy was studied using multiple strain microbes from microwave irradiation (MI) pretreated sago waste. Sago waste (SW) was MI-pretreated for reducing sugars production using 2 heating media (water and sulfuric acid) under pretreatment conditions including MI power, pretreatment duration, and solid loading. When water was used, the pretreatment parameters were optimized us...

Synergies Between Heme Peroxidases and Cellulases in the Bioconversion of Lignocellulosic Feedstocks to Ethanol

Synergies Between Heme Peroxidases and Cellulases in the Bioconversion of Lignocellulosic Feedstocks to Ethanol Christine Kelly, Oregon State University OVERVIEW Forest thinning, particularly forestry wastes composed of softwoods, in the Western region are a major potential source of biomass for biofuel production. However, softwoods, such as Douglas fir, tend to be more resistant to conversion...

Genetically Modified Lignocellulosic Biomass for Improvement of Ethanol Production

Production of ethanol from lignocellulosic feed-stocks is of growing interest worldwide in recent years. However, we are currently still facing significant technical challenges to make it economically feasible on an industrial scale. Genetically modified lignocellulosic biomass has provided a potential alternative to address such challenges. Some studies have shown that genetically modified lig...
