Nine strains of anaerobic fungi, assigned to the genera Neocallimastix and Piromonas, have been isolated from samples of ruminal digesta obtained from sheep and cattle in temperate Australia. Two strains of Sphaeromonas were also isolated from sheep. The patterns of utilization of mono-, oligo- and polysaccharides were determined for these fungi, four Neocallimastix spp. from Britain and New Zealand, and two Piromonas spp. from Britain. All 17 strains utilized cellobiose, fructose, gentiobiose, glucose and lactose. The seven Neocallimastix spp., whether from sheep or cattle, also fermented cellulose, glycogen, inulin, maltose, raffinose, starch, sucrose, xylan and xylose. Both Sphaeromonas isolates also fermented xylan and xylose. The eight Piromonas strains displayed a diversity in carbohydrate utilization, and could not be formed into a cohesive group. The metabolic endproducts of one strain each of Neocallimastix, Sphaeromonas and Piromonas were determined. They all produced acetate, formate, D(-)-lactate, ethanol and CO2 during glucose fermentation.
从澳大利亚温带地区绵羊和牛的瘤胃消化物样本中分离出了9株厌氧真菌，分别归属于新美鞭菌属（Neocallimastix）和梨形鞭菌属（Piromonas）。还从绵羊中分离出了2株球形鞭菌属（Sphaeromonas）的菌株。测定了这些真菌、来自英国和新西兰的4株新美鞭菌属菌株以及来自英国的2株梨形鞭菌属菌株对单糖、寡糖和多糖的利用模式。所有17株菌株都能利用纤维二糖、果糖、龙胆二糖、葡萄糖和乳糖。7株新美鞭菌属菌株，无论来自绵羊还是牛，都能发酵纤维素、糖原、菊粉、麦芽糖、棉子糖、淀粉、蔗糖、木聚糖和木糖。2株球形鞭菌属菌株也能发酵木聚糖和木糖。8株梨形鞭菌属菌株在碳水化合物利用方面表现出多样性，无法形成一个连贯的类群。测定了1株新美鞭菌属、1株球形鞭菌属和1株梨形鞭菌属菌株的代谢终产物。它们在葡萄糖发酵过程中都产生乙酸、甲酸、D(-)-乳酸、乙醇和二氧化碳。
