The efficiency of cyanobacterial strains as biodiesel feedstock varies with the dwelling habitat. Fourteen indigenous heterocystous cyanobacterial strains from rice field ecosystem were screened based on growth kinetic and fuel parameters. The highest biomass productivity was obtained in Nostoc punctiforme MBDU 621 (19.22mg/L/day) followed by Calothrix sp. MBDU 701 (13.43mg/L/day). While lipid productivity and lipid content was highest in Nostoc spongiaeforme MBDU 704 (4.45mg/L/day and 22.5%dwt) followed by Calothrix sp. MBDU 701 (1.54mg/L/day and 10.75%dwt). Among the tested strains, Nostoc spongiaeforme MBDU 704 and Nostoc punctiforme MBDU 621 were selected as promising strains for good quality biodiesel production by Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) and Graphical Analysis for Interactive Assistance (GAIA) analysis.
从稻田生态系统中筛选出 14 株土著异形胞蓝藻菌株，根据生长动力学和燃料参数进行筛选。生物量生产力最高的是鱼腥藻 MBDU621（19.22mg/L/天），其次是钙丝藻 MBDU701（13.43mg/L/天）。而脂质生产力和脂质含量最高的是海绵状念珠藻 MBDU704（4.45mg/L/天和 22.5%dwt），其次是钙丝藻 MBDU701（1.54mg/L/天和 10.75%dwt）。在测试的菌株中，通过偏好排序组织法富集评价（PROMETHEE）和图形分析交互辅助（GAIA）分析，选择海绵状念珠藻 MBDU704 和鱼腥藻 MBDU621 作为生产高质量生物柴油的有前途的菌株。
