Laccase production by Lepista sordida

Abstract

A Lepista sordida laccase has been characterized. Laccase and manganese peroxidase were detected in liquid medium with ammonium phosphate, yeast extract and ammonium molybdidate as nitrogen sources after 3 days of cultivation. Laccase optimal temperature and pH were 45ºC and 3.5, respectively.

Enhancement of dalesconols A and B production via upregulation of laccase activity by medium optimization and inducer supplementation in submerged fermentation of Daldinia eschscholzii

“…Similar findings were also reported in liquid culture of Lepista sordida and Streptomyces lavendulae, in which laccase activities were significantly stimulated by use of glucose and urea as supplementation nutrients(Cavallazzi et al, 2004;Jing, 2010). Based on the enhancement effect of urea on dalesconols production, the composition of M2 was modified as 20 g/1%), and pH 7.0.…”

First Record of Lepista sordida (Schumach) Singer in Eastern North Africa

“…Furthermore, L. sordida proved active role in lignin degradation, dye removal and other industrial applications. Laccases produced by L. sordida was characterized by Cavallazzi et al (2004).…”

Xenobiotics enhance laccase activity in alkali-tolerant γ-proteobacterium JB

“…They are members of the multicopper protein family that has developed from small sized prokaryotic azurins to eukaryotic ceruloplasmin. Laccases are widely distributed in plants and fungi (4), where their involvement in melanin formation and in a variety of different, and sometimes contradictory, physiological functions like fungal morphogenesis, plant pathogenesis and fungal virulence has been frequently proposed (29). They also occur in prokaryotes e.g.…”
