NOVELTY - A genetically modified Acinetobacter host for lipid production, comprises that the Acinetobacter host has been genetically modified to be deficient of one or more genes of group A or of group B or one or more genes of both groups, where the host is capable of increased production of wax esters and/or total lipids compared to the parent host, is new.    USE - The genetically modified Acinetobacter host, lipid composition, and methods are useful for producing lipids; and for producing biofuel (all claimed).    ADVANTAGE - The genetically modified Acinetobacter host is capable of increased production of TAGs and/or of total lipids compared to the parent host; and capable of increased production of wax esters and/or total lipids compared to the parent host.    DETAILED DESCRIPTION - A genetically modified Acinetobacter host for lipid production, comprises that the Acinetobacter host has been genetically modified to be deficient of one or more genes of group A or of group B or one or more genes of both groups, where group A comprises a gene encoding fatty acyl-CoA reductase (EC1.2.1.n2), gene ACIAD 3383 (fully defined 912 bp (SEQ ID NO: 1)) or a functional equivalent in an Acinetobacter host, where the host is capable of increased production of triacylglycerols (TAGs) and/or of total lipids compared to the parent host; and group B comprises a gene encoding lipase (EC:3.1.1.3), gene ACIAD 3309 (fully defined 969 bp (SEQ ID NO: 2)) or a functional equivalent in an Acinetobacter host, a gene encoding pyruvate dehydrogenase (EC:1.2.2.2), gene ACIAD 3381 (fully defined 1722 bp (SEQ ID NO: 3)) or a functional equivalent in an Acinetobacter host and/or gene ACIAD 2177 (fully defined 642 bp (SEQ ID NO: 4)) or a functional equivalent in an Acinetobacter host, where the host is capable of increased production of wax esters and/or total lipids compared to the parent host, is new. INDEPENDENT CLAIMS are: (1) a method for genetically modifying an Acinetobacter host by making the host deficient of one or more genes and optionally by introducing into the host in an operational manner one or more genes of the lipid biosynthesis pathway; (2) a process for producing lipids, comprising: cultivating Acinetobacter host or obtained by the latter method under suitable cultivation conditions; allowing Acinetobacter host to produce and/or accumulate lipids; and recovering the lipids; (3) a lipid composition produced by the process; and (4) a method for producing biofuel, comprising: cultivating Acinetobacter host under suitable cultivation conditions; allowing Acinetobacter host to produce and/or accumulate lipids; recovering the lipids; and producing biofuel using the recovered lipids as a component or as starting material for biofuel production.
