放线菌YIM30997发酵特性及其活性组分提取方法的初步研究
Fermentation characteristic of strain YIM30997 and the extraction method of its active components
【摘要】 菌株YIM30997是从云南省滇西北采集的土壤样品中分离得到的一株抗白粉病类抗生素产生菌.经发酵试验,通气量和发酵时间长短密切相关.经多种树脂吸附实验,AB-8吸附树脂具有较好吸附特性,可用于活性组分的提取和纯化.
【Abstract】 Strain YIM?30997,whose secondary products could inhibit powdery mildew efficiently,was isolated from soil samples collected in the northwestern of Yunnan P.R.China.During fermentation tests,air flow correlated closely with fermentation time.After testing various kinds of marcroporous adsorption resin,AB8 marcroporous adsorption resin had the best adsorption capacity.It can be used in extraction and purification.
