文档介绍：Preface
This volume describes recent advances in the bioconversion of lignocellulosics.
It starts with two articles on ics and properties of cellulases and their reac-
tion ics and mechanisms. The cost of cellulases has been a hindrance to
large scale use of enzymatic hydrolysis. Two articles on cellulase production by
submerged fermentation and by solid state fementation are included to describe
the state of the art in this area. Dilute acid hydrolysis of cellulose continues to be
of interest as well as potentially useful. The most recent advances in this area is
also covered. A great deal of progress has been made in ic engineering for
improved regulation of xylose fermentation by yeasts. An article on ically
engineered haromyces for simulteaneous fermentation of glucose and
xylose describes the importance advances made in production of fuel ethanol
from lignocellulosic recent years,there has been increasing interests
in recycling and the reuse of scrap paper as well as environment considerations.
A contribution is presented which describes the research perspectives in that
area. Finally, recent advances in the use of lignocellulosic biomass for the pro-
duction of ethanol anic acids are presented in two articles.
Renewable resources are inevitably of great importance in the years e.
There is a never-ending search for better living conditions for human beings.
The more resource materials can be recycled, the richer we will be. Bioconver-
sion of lignocellulosics, natural and man-made, is an important link in that
cycle. Extensive use of renewable resources will also slow down continued
deterioration of the environment.
Advances are being made as this volume is being put together. Another
volume on the same subject, perhaps, should be prepared in another ten years
or ever sooner.
