| 摘要: |
| 检测了矿物油中保存了14～45年的131株真菌,存活率为44.6%.这些存活菌株分属于真菌4个亚门中的19个属。有一种半知菌系存活达45年。不同保存期限的菌株存活率不同,保存14～16年的存活率为94.1%,26～28年的为100%,30～39年的为24.3%,40～45年的为43.3%.群体存活率与保存期限并无一致性,主要取决于群体的构成;矿物油中保存的真菌存活年限目前尚无法定论,有待进一步研究。 |

| Abstract: |
| 131 strains of fungi preserved in mineral oil were tested.The results
showed that,after long-term mineral oil preservation,about 58 strains (roughly 45.8%)
remained viable.These viable strains belonged to 19 genera in 4 mycetmycotina.One
species of the imperfect fungi lived for 45 years.The viability with different preservation
term was as follows:the viable percentage for 14-16,26-28,30-39 and 40-45 years
was 94.1% (16/17),100% (5/5),24.3%(10/42) and 43.3% (29/67),respectively.
The viable percentage of population did not show significant correlation with
preservation term, depending on the constitution of the population. At present, the
longevity of fungi preserved in mineral oil can not be unified and needs further research. |
