摘要 | 從四川省某煤礦發熱 的煤矸石堆上, 分離到一株極端嗜熱嗜酸細菌 (ES-23) , 其生長的溫度範圍為50-75'C, 最適70'C, 生長的pH範圍 為1.0-5.0, 最適pH2.0. 該菌株好氧, 兼性自養, 既能利 用有機物異養生長, 又能利用元素硫氧化產硫酸獲得能量 , 固定空氣中二氧化碳自養生長. 革蘭氏染色陰性. 細胞 球形或橢圓形,直徑0.9-1.5 micrometer. 自養生長時細 胞外有類似纖毛的附屬物. 細胞外被由分三層的膜構成, 無細胞壁. 膜脂中醚鍵代替酯鍵.DNA中G+C含量為 38mol%. 根據這些特徵, 鑑定此菌株為熱原體屬 (Thermoplasma) 的一個新種, 定名為氧化硫熱原體 (Thermoplasma thiooxidans nov. sp.) . |
Abstract | The investigators isolated two typical yeasts from China Xuanwei ham, by which the complex fermentative process of ham may be accomplishedfully and satisfactorily. Both of the vegetative cells are spheroidal or ellipsoidal and asexual reproduction is by multilateral budding onmalt extract agar. The strain S86121 forms asci and on the foru hat-shaped ascospores in each ascus on sporulated medium.The strain S86107 produce asci which contain one to three (often 1-2) hat-shaped ascospores in each ascus. The two strains, fermentating glucoseand assimilating nitrate, are identified into the genus of Hansenula H. et P. Sydow according to the direction of Kreger's yeasts monograph (1984).Further, havig been compared the distinctions between ham yeasts and their related species Hansenula holstii of the genus, the strain S86121differs markedly from the strain S86107 and Hansenula holstii in the fermentation of lactose, raffinose. The distinctions between the strain S86107and Hansenula holstii are the assimilation of lactose, raffinose, erythrole, melibiose. The strains S86107 and S86121 differ from all ofthe known species of the genus by their phsiological, biochemical and ecological characteristics. Therefore, the strains S86107 and S86121 areclaimed being two new species. The strain S86121 and S86107 are respectively are claimed being two new species. The strains S86121 and S86107are respectively named as Hansenula xuanweiensis Jiang sp.nov. and Hansenula sinensis Jiang sp. nov. |
