Abstract
VILLOTA-CALVACHI, Guido Ernesto et al. Isolated and characterization of biopolymer producing bacteria from industrial effluents. Rev. colomb. biotecnol [online]. 2022, vol.24, n.1, pp.27-45. Epub Sep 01, 2022. ISSN 0123-3475. https://doi.org/10.15446/rev.colomb.biote.v24n1.76660.
A physical-chemical characterization of effluents from industries in the education, metal-mechanic, dairy and confectionery sectors of the city of Manizales, Caldas; Later isolates were obtained, in differential media supplemented, from bacteria with potential for the production of biopolymers to which they were applied tests for morphological, biochemical and molecular characterization. The physical chemical parameters obtained from the industrial effluents show a difference between them, since each industry generates different waste contributing a certain contamination to the effluent, 73 isolates producing exopolysaccharides (EPS) and 101 producers of polyhydroxyalkanoates (PHA) were obtained, with morphological characteristics and variable biochemistry. The study shows that industrial effluents are a great source of bacteria of interest for the production of various microbial polymers; mainly those that produce polymers like intracellular biopolyesters such as PHA, due to their physical-chemical and nutritional variability allowing the microorganisms to adapt to diverse environmental and compositional characteristics.
