“…Moreover, we investigated whether variations in laccase activities as a well as in vitro production of intracellular laccase isoenzymes by P. ostreatus occurred in response to interspecies interactions with T. longibrachiatum. These data complete previous observations (Savoie and Mata 2003;Velázquez-Cedeño et al 2004) and point out the potential interest of biological induction for the production of new isoforms of laccases associated with potential variations in gene expression.…”

“…Furthermore, they were 2-25 times higher than in pure cultures depending on the species. Laccase activity peaks and the effect of interspecies interactions have also been observed in situ (Mata et al 2005;Velázquez-Cedeño et al 2004). For instance, laccase production during the vegetative growth of six Pleurotus strains in confrontation with three Trichoderma strains cultured on coffee pulp, increased at day 7, showing its maximum value at day 12.…”

“…or with microorganisms isolated from soil and lignocellulosic substrates (Baldrian 2004;Velázquez-Cedeño et al 2004). In addition to variations in enzyme activity, the pattern of excreted isoforms was affected by the interspecific interaction between P. ostreatus and T. longibrachiatum in straw-based cultivation substrates (Velázquez-Cedeño et al 2004). Thus, in this paper, we describe a very first assessment of laccase gene expression under a biotic stress using semiquantitative RT-PCR.…”

“…An increase in laccase activity produced by P. ostreatus was shown to be a general response to interactions with Trichoderma spp. or with microorganisms isolated from soil and lignocellulosic substrates (Baldrian 2004;Velázquez-Cedeño et al 2004). In addition to variations in enzyme activity, the pattern of excreted isoforms was affected by the interspecific interaction between P. ostreatus and T. longibrachiatum in straw-based cultivation substrates (Velázquez-Cedeño et al 2004).…”

Interspecific interactions with Trichoderma longibrachiatum induce Pleurotus ostreatus defence reactions based on the production of laccase isozymes

Laccases are phenoloxidases involved in aromatic compound transformation but also in stress response towards antagonist species such as Trichoderma sp. In this study intracellular isoforms of laccases produced by Pleurotus ostreatus in liquid cultures with or without Trichoderma longibrachiatum showed five isoforms with various intensities depending on the culture conditions suggesting a basal expression of these enzymes, which can be induced by interspecific interactions. A first attempt to analyse the induction of P. ostreatus laccase-gene expression by a biotic factor was realized using semi-quantitative RT-PCR. We showed that the transcription of a laccase gene of P. ostreatus can be modified by a biotic stress such as T. longibrachiatum.

“…The study by Chen et al [12] showed that laccase was significantly stimulated in the co-culture of P. radiata with D. squalens under submerged cultivation, and the improved productions of MnP and LiP were simultaneously observed in the co-culture of P. ostreatus and P. radiata. Moreover, new laccase isozymes were induced in co-cultures of P. ostreatus with T. longibrachiatum [13] and Trametes sp. AH28-2 with Trichoderma sp.…”

The lignin-modifying enzymes (LMEs) play an important role in decomposition of agricultural residues, which contain a certain amount of lignin. In this study, the production of LMEs by three co-cultivated combinations of Phlebia radiata, Dichomitus squalens and Ceriporiopsis subvermispora and the respective monocultures was comparatively investigated. Laccase and manganese peroxidases (MnP) were significantly promoted in the co-culture of P. radiata and D. squalens, and corncob was verified to be beneficial for laccase and MnP production. Moreover, laccase production by co-culture of P. radiata and D. squalens with high ratio of glucose to nitrogen was higher than low ratio under carbon- and nitrogen-meager conditions. New laccase isoenzymes measured by Native-PAGE were stimulated by co-cultured P. radiata with D. squalens or C. subvermispora, respectively, growing in the defined medium containing corncob, but the expression of laccase was greatly restrained by the co-culturing of D. squalens with C. subvermispora. This study showed that the synergistic and depressing effects of co-cultivation of P. radiata, D. squalens and C. subvermispora on LMEs were species specific.

Laccases are phenol oxidases belonging to the superfamily of multicopper oxidases and are found in bacteria, fungi, lichens, higher plants, and insects. Over the past few decades, laccases and laccase mediator systems (LMS) have found uses in a wide range of technological applications such as textile dye decolorization, industrial wastewater detoxification, pulp bleaching, chemical synthesis, and development of miniaturized biosensors. This has encouraged numerous studies to find and purify laccases with exploitable characteristics. The main aim of the present review is to summarize the rich literature data gained in recent years from the studies on laccases, focusing on the organisms that produce them, the methods used for screening, laccase activity assays, purification strategies, and the application of laccases as eco-friendly biocatalysts.
