| 摘 要： | 对取自昆仑山垭口2m钻孔的21个样品中的微生物进行了分离鉴定，并对其生长速度和耐药性进行了初步分析，结果表明：青藏高原多年冻土中有微生物存在，其种类表现为临床少见，生长速度缓慢，冻土微生物的生长表现为嗜冷性，在35℃时生长停止，反映其有特殊的生理活动机制，分离细菌的耐药性分析，发现冻土中有较大比例的耐药细菌，反映了高原微生物的特殊性。 |
| 关 键 词： | 微生物 多年冻土 耐药性 青藏高原 生长速度 生理活动机制 |

| Abstract: | A 2-m soil core was extracted from the permafrost at the Kunlun Pass of the Kunlun Mountains within the Tibetan Plateau, China. From this core 21 samples were cut to isolating microorganisms. There were 13 strains of bacteria successfully isolated. The analyses of bacteria growth and resistance to antibiotic foundthat those strains are rare and special. The microbial growth revealed that they were psychrophilic, stopping growth at the environmental temperature of 35 o C,showing these bacteria characterized by special mechanism of physiologyin extremelycold conditions. All of them grow very slowly in the normal cultivating condition. |
| Keywords: | microorganisms permafrost resistance to antibiotic Tibetan Plateau |
