“…Yeast extract also supplies certain other essential nutrients to the organism in addition to nitrogen. Stimulation of fungal growth and enzyme synthesis by added yeast extract has previously been reported for different white rot fungal strains (Sannia et al 1986;Garzillo et al 1992).…”

A solid state fermentation (SSF) process for the production of lignin peroxidase was optimized to enhance enzyme production by Phanerochaete chrysosporium. Optimization of the corncob SSF medium caused a significant reduction in fermentation time to give maximum lignin peroxidase yield. Supplementation of the SSF medium by low concentrations of peptone, yeast extract and Tween-80 enhanced lignin peroxidase production. Maximum yield of lignin peroxidase was 13.7 U/gds (units per gram dry substrate) noted after 5 days of SSF with 70% moisture and 20% (v/w) inoculum.

“…There are some reports about constitutive laccase, which are produced in media without inducers. But in the presence of inducers production of laccase greatly increases [30,31]. Different compounds, such as phenolic substrates of laccases as well as non phenolic aromatic substances, can act as inducers.…”

The laccase induction in submerged culture of basidiomycete Cerrena unicolor VKM F-3196 was investigated. Cu(2+) at concentration 0.1 mM was an optimum inducer of C. unicolor laccase. Two isoforms of laccase, namely LacC1 and LacC2, were isolated and characterized. The isoforms were shown to have different physical-chemical and catalytic properties. On the basis of the MALDI TOF MS analysis of tryptic cleavage products of both the proteins and N-terminal amino-acid sequences analysis two isoforms of laccase (LacC1 and LacC2) were classified as products of two different genes.

“…However, a number of other studies suggest that laccase does have (1976) demonstrated diminished ability to degrade lignin in laccase-minus mutants of Sporotrichum pulverulentum but this was recovered in laccase-plus revertants. Similarly, Platt et al (1984) reported that Iaccase-deficient strains of Pleurotus streams were unable to degrade lignin whereas Garzillo et al (1992) showed that P. ostreatus laccase-plus strains could degrade it in the absence of lignin peroxidase activity. Bourbonnais and Paice (1992) reported demethylation and lower lignin content (based on Kappa reduction) of Kraft wood pulp incubated with a purified laccase from C. versicolor.…”
