Investigation of Potential Risks in Bio‐Based Food Contact Materials (FCMs) From Microbial Exploitation of Agricultural Wastes: Case Studies of Bacterial Cellulose and Nisin [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT In the context of the circular economy and the increasing demand for safe and sustainable packaging, this work addresses the safety assessment of food contact materials (FCMs) derived from agro‐industrial by‐products. Despite growing interest in these bio‐based materials, the literature still lacks a structured safety‐assessment framework able

Bioconversion of Glycerol to Dihydroxyacetone by Immobilized Gluconacetobacter Xylinus Cells [PDF]

International Journal of Chemical Engineering and Applications, 2013
In this study, Gluconacetobacter xylinus cells were immobilized in calcium alginate and chitosan-coated alginate beads. The immobilized cells were used in the conversion of glycerol to dihydroxyacetone (DHA) in a stirred-tank reactor. Fermentations using free cells and 2% (w/v) initial glycerol yielded 6.3 gL -1 DHA after 60 h.

A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications. [PDF]

Geobiology
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,
