Cephalostachyum pergracile,only one bamboo for cooking rice with a section of thick bamboo,is a rare bamboo species with significant academic values and special cultural connotation in the study of plant taxonomy.Based on preliminary analysis of the values for integrated development of Cephalostachyum pergracile,the author proposes the schemes mainly for developing a series of food products,bamboo pulping,bamboo handicrafts and cosmetics as well as special foods good for health.

The paper introduced the types, mechanism and characteristics of DNA molecular markers, and sum-marized the current study of DNA molecular markers in bamboo plants.In addition, the application and the pros-pect of using DNA molecular markers in the bamboo genetic diversity were reviewed.

In this experiment,Thermomonospora fusca was chosen as an original strain for screening high yield cellulase mutants.The spore suspension of organism was treated with ~(60)Co gamma rays.A high cellulase-producing mutant strain AV5 was obtained by screening using the methods of transparent zone and shaking culture.The activity of mutant strain AV5 was enhanced for 1.8 times comparing with that of the original strain.After fermentation the excrement of cattle,the reducing rate of the crude cellulose of excrement is 32.95 %,which is 1.7 times higher than the reducing rate of the original strain.

随着我国畜牧业的蓬勃发展,生产规模化、集约化趋势越来越明显,在给人类提供丰富的畜禽产品同时,由于规模化养殖场的畜禽粪便和污水多不处理直接用作肥料,某些地区甚至直接排入江河,造成严重的环境污染.其实,畜禽粪便并非完全是不可利用的废物,粪便中有一部分营养物质能被动物直接再吸收,还有一部分物质可通过处理再被动物吸收.现在被各国所接受和使用的主要处理方法有以下几种.

食用菌生产原种和栽培种常用棉壳或木屑，少数使用麦粒或玉米粒等颗粒种，工厂化生产使用液体菌种。其实，食用菌生产使用稻谷颗粒种效果更好。
