Soil samples collected from two hot springs, Soldhar and Ringigad, both located in the Garhwal region of Uttaranchal Himalaya were analysed for their physical, chemical and microbial components. The alkaline pH, total absence of carbon and nitrogen, and high temperature were features common to soil samples from both sites. The Soldhar samples contained higher amounts of Cu, Fe and Mn. Ringigad soil was devoid of Cu, but had much higher phosphate. While the optimum incubation temperature for isolating the maximum microbial counts from soil samples from the two sites was 50 degrees C, microbial growth in broth was also observed when incubated at 80 degrees C. Microscopic examination revealed three types of microbial populations, i.e., bacteria, yeast and filamentous organisms. The soil samples were found to be dominated by spore forming rods. Out of 58 aerobic isolates, 53 were gram positive bacilli. Gram positive anaerobic oval rods were also observed up to 60 degrees C. Soil dilution plates revealed the presence of antagonistic and phosphate solubilizing populations.

乌塔兰恰尔喜马拉雅山两个温泉中土壤的微生物多样性。

分析了从都位于喜马拉雅北方邦加尔瓦尔地区的两个温泉（索达尔和林加德）的土壤样品的物理，化学和微生物成分。碱性pH值，完全不存在碳和氮以及高温是这两个地点的土壤样品共有的特征。Soldhar样品中含有较高含量的Cu，Fe和Mn。Ringigad土壤不含铜，但磷酸盐含量高得多。虽然从两个地点的土壤样品中分离出最大微生物数量的最佳孵育温度为50摄氏度，但在80摄氏度孵育时也观察到了肉汤中微生物的生长。显微镜检查显示了三种微生物种群，即细菌，酵母和丝状生物。发现土壤样品以孢子形成棒为主。在58个有氧菌株中，有53个是革兰氏阳性细菌。在高达60摄氏度的温度下也观察到革兰氏阳性厌氧卵形棒。土壤稀释板显示存在拮抗和磷酸盐溶解种群。
