The present invention provides for a polyketide synthase (PKS) capable of synthesizing an even-chain or odd-chain diacid or lactam or diamine. The present invention also provides for a host cell comprising the PKS and when cultured produces the even-chain diacid, odd-chain diacid, or KAPA. The present invention also provides for a host cell comprising the PKS capable of synthesizing a pimelic acid or KAPA, and when cultured produces biotin.

The present disclosure relates to a production medium for microorganisms converting methanol to an organic acid and a culture process, wherein the converted organic acid is oxalic acid, and the production medium for microorganisms comprises 1 to 5% of methanol, 1 to 5% of xylose, and 0.01 to 0.05% of calcium chloride relative to 1 L of the total medium, and further comprises potassium dihydrogen phosphate (KH.sub.2PO.sub.4), ammonium sulfate ((NH.sub.4).sub.2SO.sub.4), magnesium sulfate (MgSO.sub.4), iron sulfate (FeSO.sub.4), manganese sulfate (MnSO.sub.4), zinc sulfate (ZnSO.sub.4), or boric acid (H.sub.3BO.sub.3). According to the present disclosure, provided is an organic acid production process using microorganisms of the genus Aspergillus (Aspergillus. sp), which enables a high-throughput production of high-value-added value organic acids such as oxalic acid by utilizing methanol obtained as a product from refining Cl gas such as methane.

The present invention relates to a process for valorization of low-cost alkane rich feedstock. More specifically, the present invention relates to the selective conversion of alkane rich kerosene to value-added products like mono/dicarboxylic acid, fatty acids and biosurfactants using mutant yeast strain and a heterogenous nano-catalyst. The present invention also provides a mutant yeast strain for selective conversion of alkane rich refinery stream from a substrate containing hydrocarbons. The mutant yeast strain of the present invention is able to consume the sulfur content in the feed and results in the desulfurization of the alkane rich feedstock.

The present invention relates to genetically modified bacteria and methods of optimizing genetically modified bacteria for the production of a metabolite.
