This study, aimed at maximizing the biogas yield from the co-digestion of food waste (FW) and cymbopogon citratus (CC) was done in reactors (Rs) I–V at temperature of 36 ± 2 °C. Rs I, II, III, IV and V with respective FW: CC of 100:0; 80:20; 60:40; 40:60; 0:100 had mean biogas yield of 0.41 ± 0.02, 0.68 ± 0.05, 0.49 ± 0.02, 0.29 ± 0.01, and 0.22 ± 0.03 L/gVS, respectively. From the modeling result, while R I had the least latency (λ) of 3.9, RV had the highest value of 11.2 days. RII also had a reasonably low latency (λ) of 5.2 days. Top maximum specific biogas yield (R_m) of 0.48 L/gVS/day and maximum biogas production potential (A) of 19.9 L/gVS were obtained from RII. The high R² values of 0.99–0.89 obtained from the simulation analysis showed a good fit with the modified Gompertz model. The study has revealed that FW: CC of 80: 20% could be most appropriate for optimal biogas production.

这项研究的目的是在36±2°C的反应堆（Rs）I–V中，最大程度地利用食物垃圾（FW）和柠檬香茅（CC）共同消化产生的沼气产量。I，II，III，IV和V分别具有FW：CC为100：0；80:20; 60:40; 40:60; 0：100的平均沼气产量分别为0.41±0.02、0.68±0.05、0.49±0.02、0.29±0.01和0.22±0.03 L / gVS。从建模结果来看，尽管RI具有3.9的最小延迟（λ），但RV具有11.2天的最高值。RII还具有5.2天的合理低延迟（λ）。从RII获得的最高最大比沼气产量（R _m）为0.48 L / gVS /天，最大沼气生产潜力（A）为19.9 L / gVS。高R从仿真分析中获得的0.99-0.89的^2个值表明与改进的Gompertz模型非常吻合。研究表明，FW：CC的80：20％可能最适合最佳沼气生产。
