Bioglycerol, with its growing production as a co-product of biodiesel, is an attractive low-cost feedstock for the synthesis of platform chemicals by microbial fermentation. 2,3-butanediol (2,3-BDO) is amongst the top biorefinery platform chemicals that can be produced by glycerol fermentation. RESULTS The {\textquoteleft}Circular Economy{\textquoteright} concept is demonstrated by converting the by-product bioglycerol using a cell-free extract of Enterobacter aerogenes NCIM 2695 (National Collection of Industrial Microorganisms, NCIM), yielding 22 g L-1 2,3-BDO, in 96 h, 98\% atom economy and 0.4 g/g E factor. The cell-free bioglycerol conversion to 2,3-BDO was proved using a modified procedure for determining glycerol dehydrogenase enzyme assay by protein analysis and it was also shown to be cell-bounded. CONCLUSION Our study offers an effective utilization of the leftover material (i.e. cell-free extract) that biocatalysed C3 to C4 diol, which adds value to the overall economics of the process using only crude glycerol (C3) itself as a fermentative medium.</p>

	One of the finest approaches towards sustainable waste management is its effective valorization to value-added products (VAPs). Waste valorization is garnering considerable attention since it delivers substantial advantages, including environmental stability and a sustainable and viable platform for producing different VAPs. One such VAP is the poly gamma glutamic acid (\&amp; gamma;- PGA), an extortionate biopolymer known to date. Its exorbitant cost is the main barrier preventing \&amp; gamma;- PGA from becoming commercially viable. Hence, the key to the successful commercialization of \&amp; gamma;- PGA is its sustainable and cost-effective production. In the present study, the ability of Bacillus paralicheniformis NCIM 5769 to utilize molasses for \&amp; gamma;-PGA production with minimal nutrients was investigated. Results showed that 30\% molasses combined with 2\% ammonium nitrate was the optimal medium for \&amp; gamma;-PGA production. Additionally, the anti-drought activity of the synthesized \&amp; gamma;-PGA was evaluated on wheat plants showing significantly higher shoot length, biomass content, and germination rate compared to the control group. These findings suggest that \&amp; gamma;-PGA produced from molasses has the potential to be used as a drought mitigator in wheat plant, thereby achieving the mission of circular economy and sustainable development goal (SGD) 12, i.e. pursuing sustainability patterns for consumption \&amp; production.</p>
