It is now well established that zoospore-producing fungi that are able to weaken fiber and disrupt lignified tissues of forage are an integral part of the anaerobic microbial population of the rumen of herbivores. These fungi produce cellulases, xylanases and other enzymes that break down the complex polymers of plant cell wall material. To date, isolations of anaerobic zoosporic fungi have been limited to rumen fluid and feces. However, there is ample evidence to suggest that these fungi are able to survive and grow outside the host animal. The objective of this project is to isolate, examine and characterize zoosporic fungi from natural anaerobic environments such as ponds, marshes and landfills. %%% Results from this project would be used to set up experiments to determine the possible role of these fungi in the degradation of naturally-occurring recalcitrant fibrous material.

现在已经很好地确定， 能够削弱纤维并破坏草料的木质组织 是厌氧微生物种群的组成部分， 食草动物的瘤胃 这些真菌产生纤维素酶、木聚糖酶和 其他分解植物细胞复杂聚合物的酶 墙体材料 到目前为止，厌氧游动孢子真菌的分离 仅限于瘤胃液和粪便。 不过有 有充分的证据表明这些真菌能够存活， 在宿主动物体外生长 该项目的目标是 从天然植物中分离、检测和鉴定游动孢子真菌 厌氧环境，如池塘，沼泽和垃圾填埋场。 %%% 该项目的结果将用于建立实验， 确定这些真菌在降解 天然存在的柠檬酸纤维材料。
