A lubricating oil composition is provided comprising a major amount of an oil of lubricating viscosity and a minor amount of at least one trinuclear molybdenum compound. Preferably, the trinuclear molybdenum compound is selected from those compounds having the formula Mo,S,L,Q,and mixtures thereof in which L is a ligand having organo groups with a sufficient number of carbon atoms to render the compound soluble in the oil, k varies from 4 through 7, Q is selected from the group of compounds having lone pair electrons including water, amines, alcohols, phosphines, and ethers, and z ranges from 0 to 5. In general, the organo groups of the mono-anionic ligands will be the same although they may be different, and they preferably are selected from alkyl, aryl, substituted aryl, and ether groups. For example, when L is a dialkyldithiocarbamate or a dialkyldithiophosphate, the alkyl groups will have from about 1 to 30 carbon atoms.

The present invention includes microorganisms that are resistant to non-aqueous solvents. In addition, the organisms of interest are able to grow and/or carry out various organic (e.g. hydrocarbon) transformations in non-aqueous/aqueous mixtures. The invention also includes a gene which encodes an enzyme, hydroperoxide reductase, which renders the host microorganism resistant to many organic solvents. The invention also includes the operon which includes the mutant gene and the ahpF gene which encodes an NAD(P)H dehydrogenase. The invention also includes a plasmid vehicle and a host microorganism containing these genes. The invention also includes cloning the genes encoding for solvent-resistance into other organisms rendering them solvent-resistant. In addition, the genes encoding for a specific organic or hydrocarbon transformation are placed into the solvent resistant microorganism.
