| Popis: | This paper describes for the first time in detail the lignocellulose degradation system in Paecilomyces inflatus. The fungal genus Paecilomyces contributes the carbon turnover from lignin and carbohydrate plant residues, particularly in compost and soil environment, where basidiomycetes appear very seldom. We studied three different strains of P. inflatus, obtained from different ecophysiological and geographical origin. Various cultivation conditions were employed, and the chemical analysis of decayed straw, compost, birch and spruce wood chips indicated variable responses. Endoglucanase, xylanase and laccase were assayed. All strains of P. inflatus, regardless of their origin, altered the ambient pH in a similar manner in all investigated substrates, suggesting that all P. inflatus isolates may share the common regulatory system to control their environmental pH. The variability among strains of P. inflatus in their ability to remove lignocellulose components often was related to the nature of the substrate and the production of specific enzymes although it was not strictly correlated. This may implicate that other enzymes and/or even other parameters needed for lignocellulosics degradation in P. inflatus should be evaluated. Indications for specific adaptation strategies that may operate in P. inflatus were found. |
