Combined with their rapid growth rates, high starch, and low lignin contents, duckweeds have also gained popularity as a biofuel feedstock for thermochemical conversion and alcohol fermentation. However, studies on the acidogenic anaerobic digestion of duckweed into carboxylic acids, another group of chemicals which are precursors of higher-value chemicals and biofuels, are lacking. In this study, a series of laboratory batch experiments were performed to determine the favorable operating conditions (i.e., temperature and pH) to maximize carboxylic acid production from wastewater-derived duckweed durBiotechnology for biofuelsEffect of pH and temperature on microbial community structure and carboxylic acid yield during the acidogenic digestion of duckweed.PMC61745532012-68005-19703Shreve MJBrennan RACalicioglu ORichard TLfalseEffect of pH and temperature on microbial community structure and carboxylic acid yield during the acidogenic digestion of duckweed.<h4>Background</h4>Duckweeds (Lemnaceae) are efficient aquatic plants for wastewater treatment due to their high nutrient-uptake capabilities and resilience to severe environmental conditions.
