Abstract: The present invention relates to a genetically modified Acinetobacter host for lipid production. The Acinetobacter host has been genetically modified to be deficient of one or more of genes A) a gene encoding fatty acyl-CoA reductase (EC1.2.1.n2), wherein said host is capable of increased production of TAGs and/or of total lipids compared to the parent host; and/or B) a gene encoding lipase (EC:3.1.1.3), a gene encoding pyruvate dehydrogenase (EC:1.2.2.2), and/or gene ACIAD 2177, or functional equivalents of any of said genes, wherein said host is capable of increased production of wax esters and/or total lipids compared to the parent host.

Abstract: The invention relates to a method for determining a factor affecting a cell, which affects directly or indirectly the DNA, RNA and/or proteins of the cell or their synthesis machinery, in which recombinant DNA plasmid is transferred into the cell, and the initial point or points of the reproducing machinery responsible for its replication are subject to an adjustable promoter, which is controllable either by positive or negative feedback; the cell containing the recombinant DNA plasmid is brought into contact with the affecting factor; the affecting factor is allowed to affect the cell containing the recombinant DNA plasmid for a suitable time, after which the promoter adjusting the starting point of the reproducing machinery responsible for the replication of the recombinant DNA plasmid starts growing in the cell, unless the affecting factor has not inhibited the replication of the plasmid; the shift of the copy number of the recombinant DNA plasmid in the cell is determined directly or indirectly.

Abstract: The invention relates to a method for determining a metal present in a sample, in which methoda) a recombinant DNA plasmid the copy number of which is under the control of a promoter regulatable by the metal is transferred into the cell, or a recombinant DNA plasmid the copy number of which can be varied between 1 and 2000/cell is transferred into the cell, and the plasmid contains as a marker protein a DNA sequence coding for a virus, procaryotic cell or eucaryotic cell protein or for a portion thereof essential for its biological activity, the expression of the DNA sequence being under the control of a promoter regulatable by the metal and being controlled by negative and/or positive feedback;b) the cell containing the recombinant DNA plasmid is contacted with a metal-containing sample;c) the metal is allowed to affect for a suitable time the cell which contains the recombinant DNA plasmid, whereafter the amount of recombinant DNA plasmid or the amount of protein encoded by it is determined by either physic
