CA 2678787

Embodiments of the invention relate to the microbial production of polyhydroxyalkanoic acids, or polyhydroxyalkanoates (PHA), from substrates which cannot be used as a source of carbon and/or energy for microbial growth or PHA synthesis and which have microbial and environmental toxicity. According to one embodiment of the invention, a process for the production of PHA is provided wherein an enzyme such as methane monooxygenase is used to convert volatile organic compounds into PHA through the use of microorganisms that are unable to use volatile organic compounds as a source of carbon for growth or PHA production.

L'invention concerne des modes de réalisation de l'invention portant sur la production microbienne d'acides polyhydroxyalcanoïques, ou de polyhydroxyalcanoates (PHA), à partir de substrats ne pouvant pas être utilisés comme source de carbone et/ou d'énergie pour la croissance microbienne ou la synthèse de PHA et ayant une toxicité microbienne et environnementale. Conformément à un mode de réalisation de l'invention, un procédé pour la production de PHA est proposé dans lequel une enzyme telle qu'une méthane monooxygénase est utilisée pour convertir des composés organiques volatils en PHA grâce à l'utilisation de microorganismes ne pouvant pas utiliser des composés organiques volatils comme source de carbone pour la croissance ou la production de PHA.
