Production of hydroxy-fatty acid derivatives from waste oil by Escherichia coli cells producing fungal cytochrome P450foxy.
Cytochrome P450foxy (P450foxy) is a fatty acid (FA) monooxygenase that is characterized by self-sufficient catalysis and high turnover numbers due to the fused structure of cytochrome P450 and its reductase. Here we found that resting recombinant Escherichia coli cells producing P450foxy converted saturated FA with a chain length of 7-16 carbon atoms to their omega-1 to omega-3 hydroxy derivatives. Most products were recovered from the culture supernatant. Decanoic acid was most efficiently converted to omega-1 to omega-3 hydroxy decanoic acids in the order of omega-1>omega-2>omega-3, with a total product yield of 47%. We also found that P450foxy was more active against physiological fatty acyl esters such as monopalmitoyl glycerol, monopalmitoyl phospholipid, and palmitoyl CoA than free palmitic acid. The bacteria producing P450foxy were applicable as biocatalysts in the production of omega-1 hydroxy palmitic acid from lard, vegetable, and soy sauce oil wastes from the food industry.
