Potential applications of bio-ligninolytic systems

摘要: Abstract Members of various fungal taxa and actinomycetes have been shown to degrade lignin at least partially. The white-rot wood-decomposing basidiomycetes completely metabolize the complex polymer, exhibit highest reported rates, are most studied. Evidence indicates that their degradation involves oxidative, non-specific reactions, but nature catalysts reactive species remain undefined; not separated from living cells. Culture conditions optimal for metabolism by fungi described, several potential applications whole ligninolytic cultures explored preliminarily: (a) partial delignification production cellulosic products (bio-mechanical pulping, bio-bleaching); (b) conversion lignocellulosics (improving ruminant digestibility, cultivating edible mushrooms) into feed food; (c) treatment lignin-derived wastes (decolorizing, removing BOD, COD). possibility biomodify by-product lignins yield valuable polymeric or low molecular weight chemicals has approached experimentally, is another area application. Improved waste processes might well be first intentional application bioligninolytic systems.
