菌种退化 meaning in Chinese

spawndegenerationn

Examples

  1. In the artificial - planting , the strain of cordyceps militaris is easy to degenerate . at present , the study about the fungus in cordyceps genus are just in the identification of fungi 、 the nutrition analysis 、 the using in medicine and artificial - planting . although , it could reduce the lost by the usual breeding way , we could not solve the problem at basic . about the degeneration of strain , people mostly use the gender - cycling 、 the fusing - cytoplasmic technology and the genetic - engineering method to reform the strain . most of people use moleculor method in the study of relationships among the species and between the species
    用常规选育方法虽然能减少一定的损失,但不能从根本上解决菌种退化这一长期困扰企业生产的问题。针对菌种退化问题,主要是利用有性循环、原生质体融合和遗传工程等途径进行菌株改良,应用分子生物学手段只是研究种内、种间的系统关系等,而关于菌种退化遗传机理的研究尚未见报道。菌种退化是菌类栽培过程中普遍存在的,也是生产当中迫切希望得到解决的问题。
  2. The tested isozymes included esterase ( est ) 、 superoxide dismutase ( sod ) 、 malate . dehydrogenase ( mdh ) 、 malic enzyme ( me ) 、 glutamate dehydrogenase ( gdh ) 、 peroxidase ( per ) and alcohol dehydrogenase ( adh ) . there were obvious differences between the normal strain and its degenerative strain in est 、 mdh 、 me 、 sod . the zymotype were the same in the other isozymes . the results were not only used to test the degenerative strain at young stage , but also as the theoretical base to study the genetic mechanism of the degenerative strain
    而其余四种酶在正常菌株和退化菌株中酶谱一致。本研究不仅可以作为菌株退化早期鉴别的手段之一,而且为进一步研究菌种退化遗传机理提供了蛋白质水平上的一些理论依据。
