摘要

对全球变暖和化石燃料对环境的不利影响的关注促使人类寻找可再生、可持续和环境友好的燃料替代品。这得到了全球各国政府和非政府组织的充分支持。无花果(Ficus carica)是一种可食用的地中海水果,在土耳其大量种植。废无花果有致癌和产毒作用。因此,将其转化为增值产品是一个很好的选择。本研究的主要目的是研究阳离子(Zn2+, Mg2+和Mn+)和电子介质(中性红和紫甲基)对ABE过程中丙酮生成和溶剂生成阶段的影响。本研究采用单因素单次(OFAT)简单实验设计。有机酸(乳酸、乙酸和丁酸)和有机溶剂(乙醇、丙酮和丁醇)是ABE(丙酮-丁醇-乙醇)发酵的主要产物。结果表明,乳酸、乙酸、丁酸、乙醇、丙酮和丁醇的最大浓度分别为MV15(mg/L)、Mg400(mg/L)、Mg400(mg/L)、NR15(mg/L)、Mn56(mg/L)和MV15(mg/L)。

Fig (Ficus carica) Valorization via ABE Fermentation into Organic Acids and Solvents
The concern on the adverse environmental effects of global warming and fossil fuel challenged human intellect to find renewable, sustainable and environmentally friendly fuel substitutes. This was fully supported by governmental and non-governmental organizations across the globe. The fig (Ficus carica) is an edible Mediterranean fruit that is abundantly cultivated in Turkiye. Waste figs are carcinogenic and toxigenic. Thus, it’s a good option to converting it into value added products. The main objective of this research is to study the effects of cations (Zn2+, Mg2+ and Mn+ ) and electron mediators (Neutral red and Methyl viologen) on the acetogenesis and solventogenesis stages of the ABE process. One factor at a time (OFAT) simple experimental design was employed in this study. Organicacids (lactic, acetic and butyric acid) and organic solvents (ethanol, acetone and butanol) are the main product of the ABE (Acetone-Butanol-Ethanol) fermentation. From the results, maximum concentrations of Lactic, acetic, butyric acid, ethanol, acetone and butanol were recorded at MV15(mg/L), Mg400(mg/L), Mg400 (mg/L) NR15(mg/L), Mn56(mg/L), and MV15(mg/L) respectively.
