  • Publication number: 20140011224
    Abstract: The present invention relates to a novel epoxide hydrolase enzyme which aims to achieve a high degree of resolution towards a broader range of substrates with high enantioselectivity and yields with minimal product inhibition. The invention further relates to a new bacterial strain Achromobacter sp. MTCC 5605 isolated from a petroleum-contaminated sludge sample, capable of producing the said enzyme. It is notable that the enzyme can be used as whole bacterial cell preparation, which allows continuous hydrolysis of substrates at even higher concentration and have an advantage of being recycled. The invention further relates to a process for the hydrolysis of different aryl epoxides which are potential synthons of intermediates for the synthesis of chiral amino alcohols and bioactive compounds like ?-blockers.
