为了缩短木耳的生长期限,提早其子实体的形成,以及有利于保存优良菌种的特定典型性状和优良品质,在生产实践中,经常采取组织分离的方法来培养菌种。一般在组织分离中,系采用生长旺盛的新鲜耳片,实行切割的分离方法。但由于木耳的子实体是一种胶质体,一经暴露(气生)于空气中,就很容易感染杂菌(特别是霉菌)。所以,采用气生耳片进行组织分离,菌种的提纯复壮很难得到改进。 In order to shorten the growth period of fungus, to promote the formation of its fruiting bodies, and to preserve the specific typical traits and fine qualities of fine strains, it is often practiced in the production practice to cultivate the strains by tissue separation. In general, tissue separation, the Department of the growth of strong fresh ears, the implementation of cutting separation method. However, since the fruiting body of the fungus is a kind of colloid, it is easy to infect the bacteria (especially molds) once it is exposed to the air. Therefore, the use of aerial ear tissue isolation, purification and rejuvenation of bacteria is difficult to be improved.
