| 1. | One must be wary of applying the results of experiments with pure cultures directly to soils .
人们把纯培养的试验结果直接用于土壤时必须十分谨慎。 |
| 2. | There are also some estimates of the efficiency of litter decomposition by basidiomycetes in pure culture .
也有一些关于纯培养担子菌分解落叶层效力的估计。 |
| 3. | So the preparation of a pure culture involves the isolation of a given microorganism from a mixed natural microbial population .
因此纯培养制备要从混合的天然微生物群中分离出特定的微生物。 |

) o kuntze )为菌种材料，在纯培养条件下研究了菌根真菌对儿种重金属的耐性和吸附特性。 |
| 8. | Spawn is necessary for both cultivation of edible fungi and tameness of wild mushroom . the reliable method of spawn identification is to produce carpophores by the culture , which is not only time - consuming for domestic fungi but also unuseful for untamed wild mushroom
无论是食用菌的人工栽培，还是珍贵野生蘑菇的驯化研究，都需要制备菌种并对菌种的真伪进行鉴定，其中最可靠的鉴定方法是诱导纯培养菌种产生赖以识别的子实体。 |
| 9. | In order to investigate the tolerance of ectomycorrhizal fungi to heavy metals in vitro , three culture methods , namely liquid culture without agitation , liquid culture with agitation and solid agar culture , were investigated to determine which method would give the best combination of fungal biomass and ec50 . the results indicated that liquid medium without agitation was the best culture method
为研究外生菌根真菌本身对重金属污染的耐性，比较了液体静置、液体摇床和琼脂固体培养这三种常用的菌丝体的纯培养方法，以真菌生物量大小和分离难易程度为主要指标，筛选出液体静置方法为最优方法。 |
