    Plastic pollution is bringing major environmental problems in different areas. Among the main demanders of synthetic plastic is the industry of containers and packaging used for food packaging. There has been a great interest from researchers and industries to replace common plastic with bioplastics and biomaterials derived from renewable resources. The objective of this research is to perform a bibliographic review of the biomaterials obtained by fermentation for their application as containers and packaging for raw meat products. Biomaterials certified as biodegradable and biobased can be obtained directly from residual biomass from agroindustrial processes through fermentation by microorganisms, thus economizing the production process. The major representatives of bio-based and biodegradable biopolymers are PLA (polylactic acid) and PHB (polyhydroxybutyrate) because they have physical, chemical and mechanical properties similar to the synthetic plastics used in the packaging of raw meat. These biomaterials are obtained by fermentation by bacteria using different carbon sources such as corn, molasses or sugar cane bagasse, whey, fruit peel, among others. These foods are perishable and easily spoiled due to their high water and nutrient content. The use of PLA and PHB films is a viable alternative to respond to one of the biggest challenges in the food industry, which is the extension of shelf life while maintaining the microbiological and sensory quality of meats, since these packages can provide antioxidant and antimicrobial properties to the product.
