Metabolic cascade of complex organic wastes to medium-chain carboxylic acids: A review on the state-of-the-art multi-omics analysis for anaerobic chain elongation pathways

Hyunjin Kim et al.

Summary: The production of medium-chain carboxylic acid (MCCA) from organic wastes has attracted widespread attention for its high energy content and versatile applications. Research focuses on the microbial pathways contributing to carbon chain elongation in reactor microbiomes, with diverse genomics and metagenomics studies being conducted in various fields. Future research should address co-culture and multi-omics technology for a deeper understanding of the chain elongation pathways.

Insights into the microbiomes for medium-chain carboxylic acids production from biowastes through chain elongation

Xingdong Shi et al.

Summary: Bioconversion of medium-chain carboxylic acids (MCCAs) from biowastes through anaerobic mixed-culture fermentation is a promising method for reducing fossil fuels requirement and increasing biowaste treatment capacity. However, the complex microbial interactions during MCCAs production require control methods. Research identified the primary microbial interactions in mixed-culture fermentation and proposed methods for monitoring reactor performance.

A Large-Scale Genome-Based Survey of Acidophilic Bacteria Suggests That Genome Streamlining Is an Adaption for Life at Low pH

Diego Cortez et al.

Summary: The genome streamlining theory suggests that reduction of microbial genome size optimizes energy utilization in stressful environments. In this study, a comparative genomics investigation of acidophilic bacteria was performed to examine the correlation between genome size reduction and decreasing pH. The results indicate that genome streamlining in acidophilic bacteria is supported by gene loss and reduced gene sizes, independent of other genome size constraints.

The potential of caproate (hexanoate) production using Clostridium kluyveri syntrophic cocultures with Clostridium acetobutylicum or Clostridium saccharolyticum

Jonathan K. Otten et al.

Summary: The research demonstrates that Clostridium kluyveri can perform chain elongation to produce caproate from short chain alcohols and carboxylic acids, with significantly improved production efficiency and yield in coculture. Furthermore, exploring novel coculture partners can lead to higher caproate titers, showcasing the potential of coculture biotechnology for sustainable production of caproate and other platform chemicals.

The Isolate Caproiciproducens sp. 7D4C2 Produces n-Caproate at Mildly Acidic Conditions From Hexoses: Genome and rBOX Comparison With Related Strains and Chain-Elongating Bacteria

Sofia Esquivel-Elizondo et al.

Summary: A new chain-elongating bacterium, 7D4C2, was discovered to grow at mildly acidic pH and showed higher specificity in producing n-caproate when fructose and n-butyrate were used as substrates. Comparative analysis revealed the conservation of its whole genome and reverse beta-oxidation genes among other bacteria.

The occurrence and ecology of microbial chain elongation of carboxylates in soils

Sayalee Joshi et al.

Summary: The study found evidence of microbial chain elongation activity in soils, converting carbon to butyrate, butanol, and hexanoate at high and environmentally relevant concentrations of acetate and ethanol. Some soils showed substantial chain elongation activity in microcosms with high substrate concentrations, with microbial communities dominated by Clostridium kluyveri and other Firmicutes genera not previously known to undergo chain elongation.
