Shikha Dahiya,A. Naresh Kumar,J. Shanthi Sravan,Sulogna Chatterjee,Omprakash Sarkar,S. Venkata Mohan +5 more
TL;DR: The present review highlights the various enabling bioprocesses that can be employed for the generation of energy and various commodity chemicals in an integrated approach addressing sustainability.
Journal ArticleDOI
Acidogenic fermentation of food waste for volatile fatty acid production with co-generation of biohydrogen.
TL;DR: Integrated process of VFA production from waste with co-generation of H2 can be considered as a green and sustainable platform for value-addition and illustrated the role of initial pH on carboxylic acids synthesis.
Journal ArticleDOI
Renewable hydrogen production by dark-fermentation: Current status, challenges and perspectives.
TL;DR: This review illustrates the status of dark-fermentation process in the context of process sustainability and achieving commercial success and provides an insight on various process integrations for maximum resource recovery including closed loop biorefinery approach towards the accomplishment of carbon neutral H2 production.
Journal ArticleDOI
Regulation of acidogenic metabolism towards enhanced short chain fatty acid biosynthesis from waste: metagenomic profiling
Omprakash Sarkar,A. Naresh Kumar,Shikha Dahiya,K. Vamshi Krishna,Dileep Kumar Yeruva,S. Venkata Mohan +5 more
TL;DR: A strategy for selective enrichment of the biocatalyst is evaluated by exposing it to acid-shock, followed by operation under alkaline conditions (pH 10) to enhance the VFA production from food waste.
