A review on microbes mediated resource recovery and bioplastic (polyhydroxyalkanoates) production from wastewater

Microbial Cell Factories, Journal Year: 2024, Volume and Issue: 23(1)

Published: July 1, 2024

Abstract Background Plastic is widely utilized in packaging, frameworks, and as coverings material. Its overconsumption slow degradation, pose threats to ecosystems due its toxic effects. While polyhydroxyalkanoates (PHA) offer a sustainable alternative petroleum-based plastics, their production costs present significant obstacles global adoption. On the other side, multitude of household industrial activities generate substantial volumes wastewater containing both organic inorganic contaminants. This not only poses threat but also presents opportunities get benefits from circular economy. Main body abstract Production bioplastics may be improved by using nutrients minerals feedstock for microbial fermentation. Strategies like feast-famine culture, mixed-consortia integrated processes have been developed PHA highly polluted with high loads. Various process parameters loading rate, content (volatile fatty acids), dissolved oxygen, operating pH, temperature critical roles accumulation biomass. Research advances are going on downstream recovery utilizing combination physical chemical (halogenated solvents, surfactants, green solvents) methods. review highlights recent developments upcycling resources into PHA, encompassing various strategies, processing methodologies, techno-economic analyses. Short conclusion Organic carbon nitrogen promising, cost-effective source producing bioplastic. Previous attempts focused enhancing productivity through optimizing culture systems growth conditions. However, despite technological progress, challenges persist, such low productivity, intricate processing, scalability issues, properties resulting PHA. Graphical

Thermophilic-mesophilic temperature phase anaerobic co-digestion compared with single phase co-digestion of sewage sludge and food waste

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: May 25, 2024

Anaerobic co-digestion is an effective method for addressing the issue of a single substrate not being able to achieve optimal conditions anaerobic digestion. By adjusting mixture ratio sewage sludge and food waste carbon nitrogen ratio, effectiveness thermophilic-mesophilic temperature phase (TPAcD) was evaluated in comparison mesophilic (MAcD) thermophilic (TAcD). The results indicated that TPAcD increased methane yield by 50.3% 32.7% compared MAcD TAcD, respectively. variation VFA, pH, ammonia levels demonstrated combines advantages both with higher hydrolysis rate early stage under (55 °C) suitable environment later (35 °C). kinetic parameters co-digestions also performs better. Therefore, further research on warranted due its significant improvements production rate, total yield, system stability. Additionally, contributes reducing emissions supports realization "carbon neutrality".
