In the present study, a total of 52 cyanobacterial and 57 microalgal strains belonging to different genera were investigated for their potential to produce biodiesel feedstock. Ranking of different isolates was performed employing a multicriteria decision analysis (MCDA) software, PROMETHEE, considering three important parameters, the specific growth rate, biomass productivity and lipid content. PROMETHEE offers a straightforward selection of potential isolates enumerating Phi scores. Among all the studied strains, Pseudobohlinia sp. (PbS–BHS), a unicellular green alga and a new record from Badrinath hot spring and Uttarakhand (India), was identified as the most potent candidate (Phi = 0,6053; specific growth rate = 0.7 per day; biomass productivity = 203.5 mg/L/d; lipid content = 33%). Of filamentous forms, Leptolyngbya foveolarum (LlF-RHS), isolated from Ringigad hot spring, secured the top position (Phi = 0,5017; specific growth rate = 0.38 per day; biomass productivity = 25 mg/L/d; lipid content = 13%). Nevertheless, several other microalgal [e.g., Oocystis quadricauda (OQ-SHS), Chlorella sorokiniana (CS–CHS), Coelastrum sphericum (CeS-KFS) and Scenedesmus dimorphus (SD-ADW)] and cyanobacterial [e.g., Leptolyngbya sp. (LlS-SHS), Lyngbya langerhemii (LL-RHS), Lyngbya aesturii (LA-RHS), Leptolyngbya laminosa (LlL-SHS) and Phormidium sp. (PS-DWS)] strains also depicted substantially high Phi scores. Hence, they also appear to be promising for algal biodiesel feedstock production.

在本研究中，共研究了属于不同属的 52 种蓝藻和 57 种微藻菌株生产生物柴油原料的潜力。使用多标准决策分析 (MCDA) 软件 PROMETHEE 对不同分离株进行排名，考虑三个重要参数，即比生长速率、生物量生产率和脂质含量。PROMETHEE 提供了一个简单的选择，列举了Phi分数的潜在分离株。在所有研究的菌株中，Pseudobohlinia sp。(PbS–BHS) 是一种单细胞绿藻，是 Badrinath 温泉和北阿坎德邦（印度）的新记录，被确定为最有效的候选者（Phi = 0,6053; 比增长率 = 每天 0.7；生物质生产力 = 203.5 mg/L/d；脂质含量 = 33%）。在丝状形式中，从 Ringigad 温泉中分离出来的Leptolyngbya foveolarum (LlF-RHS) 占据了榜首位置（ Phi  = 0,5017；比生长率 = 0.38/天；生物量生产力 = 25 mg/L/d；脂质含量 = 13%）。然而，其他几种微藻 [例如，卵囊藻(OQ-SHS)、Chlorella sorokiniana (CS-CHS)、Coelastrum sphericum (CeS-KFS) 和二形栅藻(SD-ADW)] 和蓝藻 [例如，Leptolyngbya sp。(LlS-SHS)、Lyngbya langerhemii (LL-RHS)、Lyngbya aesturii(LA-RHS)、Leptolyngbya laminosa (LlL-SHS) 和Phormidium sp。(PS-DWS)] 菌株也描述了相当高的Phi分数。因此，它们似乎也有望用于藻类生物柴油原料的生产。
