Natural selection leads to efficient metabolic interactions among members of a microbiome, most often in association with the consumption of carbon and energy sources. A classic example of such is anaerobic digestion (AD), where organic matter in wastewater is transformed into methane, thereby reducing a waste stream and gaining a valuable fuel. Chemical synthesis from waste streams by mixed microbial communities is being explored to produce useful chemicals from waste organic material or CO2. Lactobacillus and Megasphaera genus can be cultured together to produce industrially useful medium-chain carboxylic acids (MCCAs). In this study, Lactobacillus amylovorus, Megasphaera hexanoica, and Megasphaera elsdenii were cultured together in food wastes to produce MCCAs under mimetic microbiome system of AD. As a result of adjusting the sodium acetate concentration with 10 g/L, hexanoic acid production (almost 9.06g/L) was optimized in case of L. amylovorus and M. hexanoica combination. |
