Analysis and study of ropiness of fermatation in the thin fermented material of sauce;

The research on biological purification of sewage treatement system in liquor production had been done by use of microbiological theories.

To ensure safe liquor production in Summer,regulation of production techniques and technical parameters and fermentation period should be done in advance in late spring,which could create favorable conditions for trans-production in Autumn.

Concretely,the application of"Yantai Liquor-making operation","Sichuan glutinous sorghum Xiaoqu liquor production techniques"and"raw materials substitute"has remarkable effects on improving liquor yield and saving grains;the merchan-d.

This article mainly introduce the application of biology technique on pulp bleaching process and it's mechanism, emphasizing the application of white-rot fungi and xylanase in biobleaching.

Preparation of cellulase-poor xylanase by Trichoderma reesei Rut C30 in batch and fed-batch fermentations and its application on biobleaching were investigated.

The results confirm that the LMS biobleaching exhibits excellent delignification selectivity.

Under these optimum conditions,the oil decoloration rate of the regenerated bleaching clay could reach 97.

In this paper regenerated protein fiber was prepared by using wet spinning process with regenerated protein /PVA(polyvinyl alcohol)as rough material.
