Title: Study of Laccase Enzyme in Degradation of Lignocellulosics
Authors: R.P. Singh, H.S. Garcha and P.K. Khanna


Laccase (E. C.; p-diphenol: O2, oxidoreductase) is an extracellular enzyme known to be involved in the degradation of lignin (Haars et Hüttermann, 1980). Though production and regulation of this enzyme has been studied from some species of white-rot fungi (Wood, 1980; Leatham, 1985), very little is known on Pleurotus, a white-rot basidiomycetous fungus which is normally cultivated on cereal straw (Garcha et al., 1984). The present study was undertaken with two aims; firstly, to assess the laccase production potential of different Pleurotus spp. in liquid medium under different nutritional conditions and secondly, to exploit the potentially screened species for laccase production in cereal straw for degradation of lignin. The information generated will address to obtain more knowledge about growth and development pattern of Pleurotus on lignocellulosics in terms of enhanced yield.
