In this study, an attempt was made to use micro-algal system for the production of biodiesel precursors and simultaneous CO(2) mitigation. Chlorella sp. was found to have a higher growth rate as compared to the other algal species tested namely Chlamydomonas sp. and Synnecococcus sp. At different CO(2) concentrations (0.03%, 3%, 10% and 15%), the lipid productivity was 23.0, 20.0 and 27.3mg/L/d respectively. Calcite produced was characterized using FT-IR, SEM and XRD. The FAME in crude biofuel was analyzed by GC-FID that found to contain palmitic acid (C16:0), docosapentaenoic acid (C22:5) and docosahexaenoic acid (C22:6). The calorific value of Chlorella sp. was found to be 29kJ/g which is higher than values reported for fresh water microalgae making it a potential candidate to be used as an alternate fuel.
在这项研究中，尝试利用微藻系统生产生物柴油前体，并同时减少二氧化碳。与测试的其他藻类物种（即绿球藻和 Synnecococcus sp.）相比，小球藻的生长速度更快。在不同的二氧化碳浓度（0.03%、3%、10%和 15%）下，脂质生产力分别为 23.0、20.0 和 27.3mg/L/d。使用 FT-IR、SEM 和 XRD 对生成的方解石进行了表征。通过 GC-FID 分析了粗生物燃料中的 FAME，发现其中含有棕榈酸（C16:0）、二十二碳五烯酸（C22:5）和二十二碳六烯酸（C22:6）。小球藻的热值为 29kJ/g，高于已报道的淡水微藻的热值，使其成为替代燃料的潜在候选者。
