  对乳酸菌降解亚硝酸盐机理进行了研究.其机理为:乳酸菌对亚硝酸盐的降解分为酶降解和酸降解2个阶段.在发酵的前期,培养液pH值＞4.5时,乳酸菌对亚硝酸盐降解以酶降解为主;发酵后期,由于乳酸菌本身产生酸,使培养液pH值降低,＜4.0后,亚硝酸盐的降解主要以酸降解为主.由于乳酸杆菌产酸能力强于球菌,乳酸杆菌降解亚硝酸盐能力大于乳酸球菌,而在发酵前期(pH值＞4.5),杆菌与球菌降解亚硝酸盐并无差别.

  -Biolog微生物自动分析系统是美国Biolog公司研制开发的新型自动化快速微生物鉴定系统,目前我国已有多家科研单位、高校和生物企业引进该鉴定系统,但多用于细菌鉴定,应用于丝状真菌鉴定的研究未见报道.该系统用于丝状真菌鉴定是以微生物对95种碳源利用的特异性和利用碳源增殖后产生的浊度变化为基础.文中基于Biolog丝状真菌鉴定的验证实验,参考Biolog系统操作手册和国家微生物资源平台技术规程的统一格式,研究制定了丝状真菌鉴定操作规程,有利于提高Biolog鉴定系统鉴定丝状真菌的应用水平.

  The effect of antioxidant in respect of preventing diseases and delaying aging has been paid attention. Searching better and higher effective antioxidant was even more important. In this article,antioxidant activity of 26 plants samples were studied by DPPH method,and DPPH free radical scavenging capability of extracts were determined. Experimental results showed that the antioxidant components were soluble in alcoholic solution but not in water; among these 26 plants,Radix sanguisorbae,Caulis spatholobi,Radix paeoniae Rubra and Polygonum cuspidate had higher antioxidant activities than other plants. Radix sanguisorbae was the highest with IC50 of 8.89 μg/mL.
