Effects of Medium on Sporification of Fusarium oxysporum Schl.

选择8种培养基,采用液体培养法,研究培养基质对尖孢镰刀菌(Fusarium oxysporum Schl.)281菌株小孢子产生量的影响,结果表明,在PDA培养基上培养144h得到最大小孢子产量1.283×109cfu/ml,与其它培养基产孢量差异显著(P=0.05)。培养至192h时,ATCC培养基的小孢子数量达到1.325×109cfu/ml,与PDA培养基之间无显著差异(P=0.05),与其它6种培养基之间差异显著(P=0.05)。综合比较8种培养基,PDA培养基培养时间短,配制简单,是较为理想的产小孢子培养基。The results of eight mediums effect on sporification of Fusarium oxysporum 281 showed that the number of sporification is 1.283×109cfu/ml in PDA medium after 144h,Significant difference were observed between PDA medium and others(P=0.05).The number of sporification is 1.325×109cfu/ml in ATCC medium after 192h,there are no significant difference between ATCC and PDA medium(P=0.05).PDA medium is suitable for sporification.福建省自然科学基金“内生生防菌短芽孢杆菌GFP标记及其对黄瓜枯萎病生防机理的研究”(2006J0068);; 福建省发改委重点项目“生物农药高毒力菌株筛选利用与菌种基因资源库的建立”(闽发改投资[2006]781号

Fingerprint analysis on methyl fatty acid and its applications in microbial study

脂肪酸甲酯谱图分析方法(Fatty Acid Methyl Ester,FAME)是鉴于脂肪酸可作为生物标记物而发展起来的分析技术。本文介绍了FAME谱图分析方法及其在微生物学领域的应用,包括在微生物检测、鉴定和微生物多样性研究中的应用。Fatty acid is an important biomarker.Its application in biology research has become increasingly popular.The method of FAME fingerprint analysis is based on fatty acid's utilization as a biomarker.This paper describes the FAME fingerprint analysis and its applications for microbial studies,including identification of unknown microbes and assessment of microbial diversity.国家863计划项目(2006AA10A211);; 福建省发展和改革委员会重点项目[闽农产(2006)10号];; 福建省青年科技人才创新项目(2003.J046
