“…), or other bio-products (like phenolic compounds, pigments, fertilizers, etc.) (Grewal et al, 2022;Singh et al, 2022).This Research Topic on Waste to wealth: A sustainable circular bioeconomy approach provided a platform for novel research that aims to suggest new multidisciplinary theoretical and experimental designs for the process of utilizing agro-industrial waste materials for biorefineries by extracting not just bioenergy and/or biofuels but also other valuable platform chemicals, oligomers, and polymers.The research focus of all the accepted papers was mainly the use of wild-type as well as genetically engineered microbes for the production of industrially important chemicals by utilizing agro-industrial wastes. The first research paper was mainly focused on the production and characterization of cellulases from Bacillus subtilis CD001 which was acidothermophilic in nature and might find widespread industrial applications in biomass…”

Fungos filamentosos crescidos em resíduos agroindústrias para uso em aplicações biotecnológicas

“…Dado que, proporcionam fontes de nutrientes para o rápido crescimento e consequente aumento da produção de pigmentos, sendo capaz de atender às altas demandas da indústria. Além disso, o uso destes substratos também reduz o acúmulo de biomassa, que em grandes quantidades pode causar deterioração do ambiente (Panesar, et al, 2015;Grewal, et al, 2022). correta e economicamente vantajosa para setores da indústria farmacêutica, alimentícia e química.…”

Production of Natural Pigments Using Microorganisms

“…Currently, the production of many natural pigments depends upon extraction from plants, which is subject to regional and seasonal limitations. , As an alternative, the production of natural pigments by microorganisms is not restricted by the above reasons and is easy to scale up. , Microorganisms can not only synthesize a variety of microbial pigments ,, but can also be engineered to produce plant and animal pigments. − For example, model species, such as Escherichia coli and Saccharomyces cerevisiae, have been developed to produce various pigments because of their clear genetic background and mature genetic manipulation tools. − However, the production of some pigments by microorganisms still faces the problems of low yield and high cost, which need to be solved by means of metabolic engineering and protein engineering as well as fermentation and extraction process optimization.…”
