天津地区师范专科学校,在原来封闭式培养的基础上,进行低温培养试验,证明在低温条件下,同样能够土法生产“九二○”。而且生长良好,为大量节省煤、电,更广泛生产应用“九二○”创造了更有利的条件。低温培养不易污染杂菌,基本上可根除常见的根霉、毛霉的污染,其含量与通常培养基本相同。据试验在接种后的30—48小时内,置25—27℃的温度下培养,以促进“九二○”菌丝快
Tianjin Normal College, in the original closed-type culture on the basis of low-temperature culture test to prove that in the low temperature conditions, the same can indigenous production “920”. And good growth, for a large number of savings in coal, electricity, more extensive application of “920” to create a more favorable conditions. Low temperature culture is not easy to contaminate bacteria, basically eradicate the common Rhizopus, Mucor pollution, its content is basically the same with the usual culture. According to the test in the 30-48 hours after inoculation, set at 25-27 ℃ temperature training to promote “920” mycelium fast
