The conventional practice in enhancing the larvae growths is by co-digesting the low-cost organic wastes with palatable feeds for black soldier fly larvae (BSFL). In circumventing the co-digestion practice, this study focused the employment of exo-microbes in a form of bacterial consortium powder to modify coconut endosperm waste (CEW) via fermentation process in enhancing the palatability of BSFL to accumulate more larval lipid and protein. Accordingly, the optimum fermentation condition was attained by inoculating 0.5 wt% of bacterial consortium powder into CEW for 14-21 days. The peaks of BSFL biomass gained and growth rate were initially attained whilst feeding the BSFL with optimum fermented CEW. These were primarily attributed by the lowest energy loss via metabolic cost, i.e., as high as 22% of ingested optimum fermented CEW was effectively bioconverted into BSFL biomass. The harvested BSFL biomass was then found containing about 40 wt% of lipid, yielding 98% of fatty acid methyl esters of biodiesel upon transesterification. Subsequently, the protein content was also analyzed to be 0.32 mg, measured from 20 harvested BSFL with a corrected-chitin of approximately 8%. Moreover, the waste reduction index which represents the BSFL valorization potentiality was recorded at 0.31 g/day 20 BSFL. The benefit of fermenting CEW was lastly unveiled, accentuating the presence of surplus acid-producing bacteria. Thus, it was propounded the carbohydrates in CEW were rapidly hydrolysed during fermentation, releasing substantial organic acids and other nutrients to incite the BSFL assimilation into lipid for biodiesel and protein productions simultaneously.

黑人士兵蝇fly幼虫对微生物发酵后的椰子胚乳废料进行增值，以同时生产生物柴油和蛋白质。

促进幼虫生长的常规做法是将廉价的有机废物与可食用的黑士兵fly幼虫（BSFL）一起消化。在规避共同消化的实践中，本研究着重采用细菌财团粉形式的外泌微生物，通过发酵过程来改性椰子胚乳废料（CEW），从而增强BSFL的适口性，从而积累更多的幼虫脂质和蛋白质。因此，通过在CEW中接种0.5wt％的细菌聚生体粉末14-21天来获得最佳发酵条件。在向BSFL饲喂最佳发酵CEW的同时，最初达到了BSFL生物量的峰值和生长速率。这些主要归因于通过代谢成本产生的最低能量损失，即 摄入的22％的最佳发酵CEW被有效地生物转化为BSFL生物量。然后发现收获的BSFL生物质包含约40重量％的脂质，在酯交换反应中产生98％的生物柴油的脂肪酸甲酯。随后，从20个收获的BSFL（校正后的几丁质含量约为8％）测得的蛋白质含量也分析为0.32 mg。此外，记录了代表BSFL增值潜力的废物减少指数为0.31g /天20 BSFL。最后揭示了发酵CEW的好处，突显了多余的产酸细菌的存在。因此，有人提出在发酵过程中，CEW中的碳水化合物会迅速水解，
