The aim of this study was to utilize the whole food waste in two stages. In the first stage, the carbohydrate and protein fractions of food waste recovered after enzymatic hydrolysis was used to cultivate heterotrophic microalgae, resulting in biomass yield of 0.346 ± 0.09 g/g_sugars and lipid yield of 0.216 ± 0.06 g/g_sugars. In the second stage, oil (14.15% w/w) was extracted from food waste after hydrolysis and converted to biodiesel by a two-step transesterification reaction that generated 135.8 g/kg_{food waste} of fatty acid methyl esters and 13.8 g/kg_{food waste} of crude glycerol. Finally, crude glycerol obtained from both processes was used at 20 g/L to cultivate heterotrophic microalgae, resulting in a cell dry weight and total lipid concentration of 6.23 g/L and 2.91 g/L, respectively. A total 248.21 g of fatty acid methyl esters were obtained from the 1 kg of food waste through this integrated process.

这项研究的目的是分两个阶段利用整个食物垃圾。在第一阶段，酶水解后回收的食物垃圾中的碳水化合物和蛋白质部分被用于培养异养微藻，生物量产量为0.346±0.09 g / g_糖，脂质产量为0.216±0.06 g / g_糖。在第二阶段中，油（14.15％w / w的）从食品废物水解后萃取并通过生成135.8克/ kg的两步酯基转移反应转化为生物柴油_{的食品废物}的脂肪酸甲基酯和13.8克/公斤_食物浪费粗甘油。最后，将从这两个过程中获得的粗甘油以20 g / L的浓度用于培养异养微藻，得到的细胞干重和总脂质浓度分别为6.23 g / L和2.91 g / L。通过这一综合过程，从1千克食品垃圾中总共获得了248.21克脂肪酸甲酯。
