Polyhydroxybutyrate (PHB) is a bacterial biopolymer with interesting features that make it useful in diverse areas of human development. The problem around this biomaterial is its high production cost, so researchers have focused their attention on the search of economic substrates to be used in the fermentation process. The present work is focused on designing a formulation based on mesquite honey and nejayote for cellular biomass and PHB generation by Bacillus cereus 4N, relying on the central compounds design and factorial design as statistical tools. The substrates employed were characterized by bromatological analysis and the biopolymer obtained from the fermentation process was analyzed by FT-IR. These results show that mesquite honey at 15 g/L influence a high cellular biomass
El concepto de biorrefinería fue creado con la intención de promover el uso sustentable de los recursos naturales para su conversión en productos biotecnológicos con valor comercial. Sin embargo, la problemática mundial de contaminación ambiental y la falta de acceso a productos de origen biotecnológico tales como vacunas, medicamentos e inclusive alimentos en poblaciones vulnerables, ponen de manifiesto la insuficiente visión de beneficio social, justicia y equidad por parte de dicho gremio industrial. Bajo este contexto, es necesario desafiar el estado actual promoviendo una insurgencia multidisciplinaria que vea prioritariamente por el desarrollo socioeconómico de las comunidades rurales y la protección de los ecosistemas nativos. Es por ello, que el presente escrito enfatiza una serie de puntos críticos que deben ser abordados antes de la instalación de cualquier biorrefinería, teniendo como base un clúster académico, gubernamental y empresarial que opere de manera íntegra.
Polyhydroxyalkanoates (PHA) are microbially produced biopolymers which are biodegradable and biocompatible. These compounds produced by microorganisms have been described as a potent alternative to synthetic plastics, which are often recalcitrant. Here, we report the draft genome sequence of a PHA-producing
