Taking the training of students' environmental protection concept as teaching training objectives,based on the guidance of the core ideology of people-oriented scientific development concept,this paper carried out teaching reform and optimization for the course of Environment Protection and Sustainable Development,so as to meet the needs of discipline development in the new situation.

In the paper,we narrative the present situation and problems on the practice teaching of vocational food professional and put forward the contents we need reforms including three sides: changing the new models to replace the traditional school model;arranging the content of practice teaching according to " basic skill project-professional skill project-comprehensive and practical work skill project" by the way of modular approach with step by step;establishing the new system on practice teaching in the manner of " three levels and three stages".

The effect on by-products of formic acid, acetic acid, levulinic acid on xylitol fermentation by Candida guilliermondii. Each byproduct was added to the med-ium with different concentrations of fermentation tests; and the results were as follows: fermentation of xylitol is most obviously inhibited by formic acid, even at the concentration of 1 g.L-1, and the fermentation of xylitol is almost completely inhibit- ed with the concentration of 5 g.L-1. 1 g.L-1 acetic acid or levulinic acid is beneficial to the fermentation, and fermentation inhibition is not obvious when their conce-ntration is less than 2 g.L-1, while the fermentation of xylitol is almost completely inhibited at the concentration of 8 g.L-1. Inhibition of xylitol fermentation basically assumes additive effect when the by-products of same sort of weak acids coexist.

实验、实训、实习三个环节与课程设计、毕业设计、学年论文、创业活动、社会调查、科技制作、学科竞赛活动等构成了实践教学的完整体系,但实验、实训、实习又是评估实践教学优劣、是否符合国家教学要求最为重要的指标。同时这三个环节又可以单独成为一个小体系,教学中应该采取由浅入深,理论联系实际,工学结合的模式来培养学生。就高职高专院校在开展和实施三环节教学过程中出现学生忽视实验原理的连贯性,操作能力差,教师重理论轻实践,学校不重视校内外实训基地建设,寻找实习单位路子单一等问题进行探讨,并对如何提高实验、实训、实习教学效果提出策略和方法。

The natural zeolite has certain pigment adsorption performance. This paper uses hydrochloric acid solution to modify the natural zeolite and to improve its adsorption ability, and analyses the influences of zeo- lite grain size, hydrochloric acid concentration, temperature and time on the modification effects. Moreover, the paper uses the modified zeolite to decolorize the sugarcane juice,and the best technological conditions under which the decolorization rate reaches 64.8% are obtained by orthogonal experiment. Finally, the paper analyses the structure eharacterizatics of modified and post--regeneration zeolite by using XRD.

With novel quartus ammonium cationic bagasse cellulose as clarifying agent of sugar juice, a series of tests carried out was presented in this paper.On the basis of monofactorial tests, the orthogonal test was designed and analysed using SPSS software.Purity improvement rate(PIR) and color value reduction rate(CVRR) were chosen as two research indicators.The optimal clarification parameters were found as follows:react temperature 80℃, and the quartus ammonium group cationic bagasse cellulose dosage 0.4g per 100mL sugar juice, contact time 40 minutes , pH 8.
