Recent developments and innovations in solid state fermentation

The aim of this review is to determine the trends of state-of-art of laccase sources, properties, structure and recent application of fungal laccase in various fields. Laccases are biotechnologically important multi copper proteins that have broad substrate specificity towards aromatic and non-aromatic compounds. Fungi are the major laccase producers especially ascomycetes, deuteromycetes and basidiomycetes, and laccases have an average molecular weight between 50 and 130 kDa. Fungal laccases are used in biotechnological applications for preparation of anticancerous and anti-oxidant hormonal drugs, stabilization of food products, and laccase application is also extended to preparation of biosensors, DNA labeling, immunochemical assay, bioorganic compound synthesis etc. The environmental application of laccase is for biodegradation of dyes, phenols and pesticides, and the mechanism of degradation has been briefly explained. Analysis of the biodegraded dye sample by FT-IR and Mass (ESI)-spectrum has been discussed in a detailed manner. Modeling kinetics has been discussed with respect to degradation of wastes in order to understand the factors involved in the degradation process.

The optimization of laccase production by Agaricus bisporus CU13 under submerged fermentation conditions was conducted via response surface methodology. Incubation period, cultivation pH value, carbon sources, and nitrogen sources parameters were studied using 2, 2´-azino-bis (3- ethylbenzothiazoline-6-sulphonic acid) (ABTS) as substrate for laccase activity evaluation. Response surface methodology (RSM) was used to optimize the fermentation medium composition through studying the major effective factors resulted from the one factor per time study as follows: pH values (pH 5.0 − 9.0), soluble starch concentration (7.5 − 17.5 g/L), yeast extract concentration (2.5 − 12.5 g/L), and incubation time (15 − 35 days). Central composite design (CCD) revealed that the pH value of 6.99, 15 g/L soluble starch, and 5.52 g/L yeast extract were the optimum values for laccase production after 24 days of incubation at 28 °C. The optimization statistics leads to the improvement of laccase activity by 156% in comparison with pre-optimization values, which reveals the efficiency of the proposed model. A. bisporus CU13 laccase was evaluated as a green alternative in dyes decolorization, where it was able to decolorize Acid Green 27 dye with decolorization percentage range of 73 to 51% at concentrations range of 25 to 200 mgL−1 after 30 min.
