Biogas production from anaerobic co-digestion of fallen teak leaves () and microalgae () were investigated. In this study, teak leaves and algae mixtures with or without pretreatment were used as the substrates and digested in 1-L of anaerobic fermenter, then optimal conditions were performed in 6-L fermenter. Pretreatment was performed using sodium hydroxide (NaOH) solution (w/v) at different conditions (0, 2, 3 and 4%), with different total solid (TS) ratios (10, 15 and 20%). The digesters were placed in an incubator at 34-36 °C for 45 days. The results showed that the co-digestion of pretreated (10% TS with 2% NaOH) of teak leaves and algae was significantly higher in terms of biodegradability of TS, VS, COD along with biogas yield, methane potential and highest yield was achieved 71.90% than those obtained by mono-digestion. Thus, results demonstrated that anaerobic fermentation of teak leaves and microalgae in digester system could get as high methane yield.
研究了柚木落叶（）和微藻（）厌氧共消化产生沼气的情况。在本研究中，将经过或未经过预处理的柚木叶和藻类混合物用作底物，在1升厌氧发酵罐中进行消化，然后在6升发酵罐中进行优化条件实验。使用氢氧化钠（NaOH）溶液（重量/体积）在不同条件（0%、2%、3%和4%）下，以不同的总固体（TS）比例（10%、15%和20%）进行预处理。将消化器置于34 - 36°C的培养箱中45天。结果表明，预处理后的柚木叶和藻类（10% TS与2% NaOH）共消化在TS、VS、COD的生物降解性以及沼气产量、甲烷潜力方面显著更高，最高产量达到71.90%，高于单消化获得的产量。因此，结果表明在消化器系统中柚木叶和微藻的厌氧发酵可以获得较高的甲烷产量。
