Non-biodegradable waste such as plastic has been the subject of attention due to its excessive use and accumulation as waste in the last 20 years, for which reason, bioplastics are positioned as relevant alternative substitutes for their easy assimilation by micro-microorganisms. The objective of this study was to characterize the microorganisms that participated in the biodegradation of a bioplastic of ethyl acrylate (AE) and tamarind xyloglucan (XgT), during a biodegradability test carried out through composting bioreactors, in order to recognize the viability of microbial development in such degradation systems. For this, primary seeding was performed on blood agar and Sabouraud, secondary seeding in IHB, medium in which 16 colonial morphologies were differentiated, with a tendency to Gram (+) bacilli; The enzymatic profile was made on starch agar (AA), skim milk agar (LD) and Baird-Parker agar (BP) to show the participation of enzymes amylase, caseinase and lecithinase; Likewise, the qualitative analysis of degradation and the plate count were made, which showed an average of 2.15x1012 CFU / mL of sample, exhibiting conditions for microbial viability in composting bioreactors.
