Kallar Kahar lake, Punjab, Pakistan is a rich source of phytoplankton which can be used for biofuel production.
This study was conducted to investigate the presence of different microalgae species present in this lake and their possible utilization for bioenergy production.
The crude culture was examined under microscope. Isolation of the identified species was carried out by using serial dilution and colony picking methods. Isolated strains were evaluated by investigating their biomass productivity, salinity resistance and auto-flocculation ability.
Four different microalgae species () were identified in the crude sample. The experimental results indicated that, among the four isolated strains, the species showed highest biomass productivity (4.2 gL) and showed comparatively higher salt resistance. also showed great potential of auto-flocculation as around 70 % of its cells sediment within 5 h without addition of any external flocculating agent. The lipid content in the isolated strains has also been carried out using Soxhlet extraction.
Four different microalgae strains have been found in Kallar Kahar lake that reflected good biomass productivity and are capable of auto-flocculation.
巴基斯坦旁遮普省的卡拉尔卡哈尔湖是浮游植物的丰富来源，可用于生物燃料生产。
本研究旨在调查该湖中存在的不同微藻物种及其用于生物能源生产的可能性。
对粗培养物进行显微镜检查。采用连续稀释和菌落挑选方法对鉴定出的物种进行分离。通过研究其生物量生产力、耐盐性和自动絮凝能力对分离出的菌株进行评估。
在粗样品中鉴定出四种不同的微藻物种（）。实验结果表明，在四种分离菌株中，物种显示出最高的生物量生产力（4.2 gL），并且显示出相对较高的耐盐性。还显示出很大的自动絮凝潜力，因为在不添加任何外部絮凝剂的情况下，约70%的细胞在5小时内沉淀。还使用索氏提取法对分离菌株中的脂质含量进行了测定。
在卡拉尔卡哈尔湖中发现了四种不同的微藻菌株，它们具有良好的生物量生产力并且能够自动絮凝。
