Members of the genera Nocardia and Streptomyces have ability to perform highly selective chemical modifications of complicated compounds of natural and synthetic origin. Nocardia strains have been found to degrade aromatic hydrocarbons by hydroxylation. Actinomycetes have the ability to hydroxylate aliphatic chains of hydrocarbons in the terminal and subterminal position and subsequently followed by shortening of the transformed chains. Actinomycetes are able to degrade certain pesticides. The herbicide, dalapon, 2, 2-dichloropropionic acid was degraded by Nocardia strains isolated from soil23.

This has not, however, discouraged the production of palm-oil methyl ester: This is because palm-oil methyl ester is one of the most successful sustainable and bio-degradable fuel oils ever synthesised from a natural product.

Palm-oil methyl ester is one of a series of "biodiesels" formed from natural oils and tested in vehicles in Europe, the United States and, more recently, in Thailand.

Nitro-organic compounds are important intermediates in the manufacture of synthetic dyestuffs.

Lipases are one of the most important industrial biocatalyst which catalyzes the hydrolysis of lipids. It can also reverse the reaction at minimum water activity. Because of this pliable nature, it is widely exploited to catalyze the diverse bioconversion reactions, such as hydrolysis, esterification, interesterification, alcoholysis, acidolysis and aminolysis. The property to synthesize the esters from the fatty acids and glycerol promotes its use in various ester synthesis. The esters synthesized by lipase finds applications in numerous fields such as biodiesel production, resolution of the recemic drugs, fat and lipid modification, flavour synthesis, synthesis of enantiopure pharmaceuticals and nutraceuticals. It plays a crucial role in the food processing industries since the process is unaffected by the unwanted side products. Lipase modifications such as the surfactant coating, molecular imprinting to suit for the non-aqueous ester synthesis have also been reported. This review deals with lipase catalyzed ester synthesis, esterification strategies, optimum conditions and their applications in food processing industries.

AB - Treatment of 5-monosubstituted Meldrum's acids with dimethylmethyleneimmonium iodide (Eschenmoser's iodide salt) in methanol gives α-substituted acrylate methyl esters in good yields. Easy access to 5-monosubstituted Meldrum's acids allowed us to synthesize a wide variety of α-substituted acrylate methyl esters. The reaction conditions are mild and tolerate many functional groups commonly used in organic synthesis; thus, this new method has potential as an alternative to conventional preparative methods for α-substituted acrylate esters.
