The present invention relates to means and methods for producing an amide compound from a nitrile compound with less acrylic acid as by-product using a Nitrile hydratase (NHase) and Amidase producing microorganism as biocatalyst. Also provided is an aqueous amide compound obtained by the methods of the invention as well as a composition comprising acrylamide or polyacrylamide as well as a dried microorganism exhibiting a NHase/Amidase activity ratio of at least 400 when being brought into contact with a nitrile compound to convert said nitrile compound into an amide compound.

The invention refers to enzymes from the wax worm (Galleria mellonella larvae) saliva which has the unexpected capacity of oxidizing and depolymerizing untreated polyolefin-derived polymers, such as polyethylene (PE), at room temperature (RT), neutral pH and short incubation times. The invention also refers to methods for biodegrading a polyolefin-derived polymer wherein this enzyme is used.

An enzyme synthesizes hydroxyl acetaldehyde and/or 1,3-dihydroxyacetone by catalyzing formaldehyde. Site-directed mutation of benzoylformate decarboxylase (BFD) creates a mutant of the enzyme, which can polymerize the formaldehyde, A phosphoketalose (F/XPK) generates acetyl phosphoric acid from the hydroxyl acetaldehyde or 1,3-dihydroxyacetone (DHA). Combination with phosphotransacetylase (Pta) provides a route from the formaldehyde to acetyl coenzyme A in three steps.
