Recombinant microalgae cells producing novel oils

A cell of the genus Prototheca comprising one or more exogenous gene, wherein the exogenous gene is a sucrose invertase gene, a fatty acyl-ACP (acyl carrier protein) thioesterase gene, a fatty acyl-CoA/aldehyde reductase gene, a fatty acyl-CoA reductase gene or a fatty aldehyde decarbonylase gene and is integrated into a nuclear chromosome of the cell, and wherein the sucrose invertase gene encodes a sucrose invertase having a catalytic activity of hydrolyzing sucrose to glucose and fructose, the fatty acyl-ACP thioesterase gene encodes a fatty acyl-ACP thioesterase having a catalytic activity of hydrolyzing a fatty acyl-ACP substrate, the fatty acyl-CoA/aldehyde reductase gene encodes a fatty acyl-CoA/aldehyde reductase having a catalytic activity of reducing a fatty acyl-CoA molecule to a primary alcohol, the fatty acyl-CoA reductase gene encodes a fatty acyl-CoA reductase having a catalytic activity of reducing a fatty acyl-CoA molecule to an aldehyde, and the fatty aldehyde decarbonylase gene encodes a fatty aldehyde decarbonylase having a catalytic activity of converting a fatty aldehyde to an alkane or alkene.
