Abstract

This study explores the impact of water quality on algal species, focusing on Spirulina spp. in Kohat, Pakistan. Spirulina spp. thrives in environments with a pH range of 9.5–10.5, elevated sodium carbonate salts, and temperatures between 30 to 35 °C. Physiochemical parameters were analyzed in water samples from various Kohat water bodies, revealing pH variations from 8.89 to 6.0, electrical conductivity ranging from 650 to 300 μS/cm, and dissolved oxygen fluctuating from 8.7 to 3.0 mg/L. Total Dissolved Solids (TDS) showed values of 380–200 mg/L, while water temperature ranged from 35.4 to 29.0 °C. Seven algal species, including Spirogyra spp., Spirulina spp., and Chlorella spp., Oscillatoria spp., Fragilaria spp., Scenedesmus spp. and Diatoms spp. were identified. Spirulina spp. correlated significantly with temperature and pH, with alkaline pH > 8.5 deemed crucial for its occurrence. The study underscores optimal culturing conditions, emphasizing the critical role of pH, advocating for morphological identification due to Spirulina spp.'s morphological plasticity.

巴基斯坦科哈特水体中螺旋藻的出现及其与物理环境因素的关系

本研究探讨了水质对藻类物种的影响，重点研究了巴基斯坦科哈特的螺旋藻。螺旋藻在pH值为9.5-10.5，碳酸钠盐含量高，温度为30 - 35°C的环境中茁壮成长。对不同科哈特水体的水样理化参数进行了分析，pH值在8.89 ~ 6.0之间变化，电导率在650 ~ 300 μS/cm之间变化，溶解氧在8.7 ~ 3.0 mg/L之间波动。水体温度为35.4 ~ 29.0℃，总溶解固定性（TDS）为380 ~ 200 mg/L。共鉴定出螺旋藻、螺旋藻、小球藻、振荡藻、Fragilaria、场景藻和硅藻7种。螺旋藻与温度和pH呈显著相关，碱性pH >； 8.5被认为是其发生的关键。本研究强调最佳培养条件，强调pH的关键作用，由于螺旋藻的形态可塑性，提倡形态鉴定。
