| Keywords: | Lactic acid bacteria Plasmid Gene cloning |

| Description: | Lactic acid bacteria play an important role in the manufacture of fermented foods. Genetic studies have made these microorganisms, particularly lactococci, accessible to genetic manipulation. The instability of key metabolic traits of lactococci has been explained by the presence of plasmid DNA species. Most genetic interest has been focused to solve the quoted instability and the sensitivity to bacteriophage infection. At the same time, gene transfer systems have been developed and specific genes with commercial significance have been identified and cloned. Lactic acid bacteria can be also used as production organisms of heterologous proteins, e.g. chymosin, lysozyme. Las bacterias lácticas juegan un papel importante en la elaboración de alimentos fermentados. La manipulación genética de estos organismos, y en particular de los lactococos, es posible gracias a los estudios genéticos realizados. La presencia de plásmidos explica la inestabilidad de las características metabólicas vitales de los lactococos. El mayor interés genético se ha enfocado en la citada inestabilidad y la sensibilidad a la infección por bacteriófagos. Al mismo tiempo, se han desarrollado sistemas de transferencia genética y se han identificado y clonado genes específicos de interés comercial. Las bacterias lácticas pueden ser utilizadas también como organismos de producción de proteínas heterólogas, tales como quimosina y lisozina. Peer reviewed |
