Laccase and oxidase
-
The process parameters influencing the production of extracellular laccases by Streptomyces lavendulae were optimized in submerged fermentation. It was made to screen, enhance and production of laccase enzyme produced by the consortium of laccase producing Streptomyces lavendulae. To date, laccases connect mostly been independently and characterized from flora and fauna of fungi and unaided fungal laccases are used currently in biotechnological applications

Phenoxazinone synthase (PHS) is a laccase-like multicopper oxidase originating from Streptomyces with great industrial application potential. In this paper, we prepared the PHS nanogel retaining 82 % of its initial activity by aqueous in situ polymerization at pH 9.3.

Fungal laccases are multicopper oxidases (MCOs) with high biotechnological potential due to their capability to oxidize a wide range of aromatic contaminants using oxygen from the air.

Laccases are multicopper oxidases, which are assigned into auxiliary activity family 1 (AA1) in the CAZy database. These enzymes, catalyzing the oxidation of phenolic and nonphenolic substrates coupled to reduction of O2 to H2O, are increasingly attractive as eco-friendly oxidation biocatalysts.

Characterization of mushroom strains on the basis of physiological conditions and enzymatic activity
A study on 18 strains of mushrooms belonging to 5 genera namely Agaricus, Calocybe, Lentinula, Pleurotus, Tricholomawas done for biochemical and physiological studies. These strains were obtained from Directorate of Mushroom Research, Solan and Mushroom Lab, RPCAU, Pusa. Radial growth measurement of mycelium for optimum growth conditions for all the strains were recorded with respect to different media, temperature and pH. The biochemical screening of enzymatic activities for all the strains was also done for lipase, amylase, laccase and oxidase.

A new exocellular laccase was purified from the basidio-mycete C30. LAC2 is an acidic protein (pI¼3.2) prefer-entiallyproducedupona combined inductionby copper and p-hydroxybenzoate.The spectroscopic signature (UV/visible and EPR) of this isoform is typical of multicopper oxidases, but its enzymatic and physico-chemical properties proved to be markedly different from those of LAC1, the constitutive laccase previously purified from the same organism.

A phylogenetic analysis of more than 350 multicopper oxidases (MCOs) from fungi, insects, plants, and bacteria provided the basis for a refined classification of this enzyme family into laccasessensu stricto (basidiomyc-etous and ascomycetous), insect laccases, fungal pigment MCOs, fungal ferroxidases, ascorbate oxidases, plant laccase-like MCOs, and bilirubin oxidases.
