生产上用的赤霉素产生菌——亦霉菌是一种丝状真菌。它在保存期间,生产特性常有减低或丧失的退化现象,这除与菌种本身的特性有密切关系外,与保存方法也有很大关系,特别是当赤霉菌在人工合成的培养基上经过多次传代后,生产性能极易降低。因此,选择能减慢菌种退化的简便易行的保存方法,是非常必要的。近年来,作者采用液态石蜡(矿油)保存赤霉菌菌种,通过对 Production of gibberellin-producing bacteria - also mold fungus is a filamentous fungus. It is often preserved during the production characteristics of reduced or lost degradation, in addition to the nature of the strain itself is closely related to the preservation method also has a great relationship, especially when the Gibberella in the synthetic medium through After many passages, the production performance can be easily reduced. Therefore, it is necessary to choose a simple and convenient method of preservation that will slow the degeneration of the bacteria. In recent years, the author uses liquid paraffin (mineral oil) preservation of Fusarium species, through
