Distribution and isolation of cellulolytic myxobacteriaWe assayed distribution of and isolated cellulolytic myxobacteria of several environmental types of samples, i.e.

为了更深入地研究和开发溶纤维素粘细菌资源，本文在溶纤维素群粘细菌的分离纯化、生态分布、系统分子分类、降解纤维素机制进行了初步探索。

Till now, Studies on Sorangium have mainly been carried out on its intriguing, novel and diverse bioactive metabolites and the genes for synthesis of these metabolites. However, to our knowledge no studies on the cellulolytic activity, the unique and basic property of Sorangium among myxobacteria have been reported yet.

目前国内外关于堆囊菌的研究大都仅仅局限于新颖、功能不同的活性代谢产物的筛选和鉴定以及代谢产物合成功能基因寻找和改造方面，而对于堆囊菌能降解纤维素大分子底物这一有别于其他粘细菌的自身独特的、最基本的特性，目前尚未见到相关的研究报道。

Myxobacteria, which are ubiquitous soil bacteria, are remarkable and unique among prokaryotes in their ability, under conditions of nutrient deficiency, to form fruiting bodies, whereby tens of thousands to millions of cells walk together in a coordinated fashion.

作为一种土壤中广泛存在的细菌，它可以在营养贫瘠的条件下形成子实体，大量细胞共同协作生活，这一特点在原核生物中独一无二。

The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

The myxobacteria have a life cycle that is dominated by social behavior. During vegetative growth, cells prey on other bacteria in large groups by gliding motility. When faced with starvation, cells form a macroscopic fruiting body containing thousands of resting myxospores.
