This study converts bakery waste into n-caproate and n-caprylate using microbial chain elongation, achieving 30-35% carbon conversion with lactate as a superior intermediate.

This study evaluates the toxicity and biodegradation of HTL process waters from food-waste and wheat straw feedstocks in anaerobic digestion, showing feedstock-specific impacts and the effectiveness of microaeration.

This study evaluates micro-aeration-enhanced anaerobic digestion for treating coffee-processing wastewater, finding it improves recalcitrant compound removal but reduces methane yield.

This paper introduces a new flat-sheet membrane bioreactor for controlled gas delivery at low fluxes, validated with oxygen and starch wastewater, showing stable performance over 320 days.

This study compares reactor configurations for lactate production from acid whey, finding that a CSTR with a hollow-fiber membrane module achieved the highest conversion efficiency and rate.

This study identifies oxygen's role in enabling renewable n-caprylate production from ethanol and acetate via intermediate metabolite synthesis in bioreactors.
