Lignocellulose biotechnology: issues of bioconversion and enzyme production

TLDR
The aim of this review is to remind ourselves and other scientists working in related areas of lignocellulose research of the enormous economic potential of the bioprocessing of residual plant materials generally regarded as “waste”, and to highlight some of the modern approaches which potentially could be used to tackle one of the major impediments, namely high enzyme cost.
Abstract
This review is written from the perspective of scientists working in lignocellulose bioconversion in a developing country and the aim of this review is to remind ourselves and other scientists working in related areas of lignocellulose research of the enormous economic potential of the bioprocessing of residual plant materials generally regarded as “waste”, and secondly to highlight some of the modern approaches which potentially could be used to tackle one of the major impediments, namely high enzyme cost, to speed-up the extensive commercialisation of the lignocellulose bioprocessing. Key words : lignocellulose, bioconversion, enzyme cost. African Journal of Biotechnology Vol. 2 (12), pp. 602-619, December 2003

Lignocellulosic residues : Biodegradation and bioconversion by fungi

TL;DR: The use of fungi in low cost bioremediation projects might be attractive given their lignocellulose hydrolysis enzyme machinery.
Journal ArticleDOI

Progress in bioethanol processing

TL;DR: A review of the biological and thermochemical methods that could be used to produce bioethanol is made and an analysis of its global production trends is carried out in this paper, where the authors evaluate the utilization of different feedstocks (i.e., sucrose containing, starchy materials, lignocellulosic biomass) is required considering the big share of raw materials in bio-ethanol costs.

Production of bioethanol from lignocellulosic materials via the biochemical pathway: a review.

TL;DR: The main problem with bioethanol production is the availability of raw materials for the production as mentioned in this paper, which can highly affect the production costs of the bio-ethanol, as the price of the raw materials is highly volatile.

A Molecular View of Microbial Diversity and the Biosphere

TL;DR: Over three decades of molecular-phylogenetic studies, researchers have compiled an increasingly robust map of evolutionary diversification showing that the main diversity of life is microbial, distributed among three primary relatedness groups or domains: Archaea, Bacteria, and Eucarya.
