Co-cultivation was a potential strategy in lignocellulolytic biodegradation with producing high activity enzymes due to their synergistic action. The objective of this study was to investigate the rarely understood effects of co-culturing of two white-rot fungi on lignin-modifying enzymes (LMEs) production. Six species, Bjerkandera adusta, Phlebia radiata, Pleurotus ostreatus, Dichomitus squalens, Hypoxylon fragiforme and Pleurotus eryngii, were cultured in pairs to study the production of LMEs. The paired hyphal interaction observed showed that P. eryngii is not suitable for co-growth. The use of agar plates containing dye RBBR showed elevated decolourisation at the confrontation zone between mycelia. Laccase was significantly stimulated only in the co-culture of P. radiata with D. squalens under submerged cultivation; the highest value was measured after 4 days of incubation (120 U mg(-1)). The improved productions of MnP and LiP were simultaneously observed at the co-culture of P. ostreatus and P. radiata (MnP = 800 nkat L(-1) after 4 days of incubation; LiP = 60 nkat L(-1) after 7 days of incubation), though it was not a good producer of laccase. P. ostreatus appeared to possess specific potential to be used in co-cultured production of LMEs. The phenotype of LMEs production was not only dependent on the species used but also regulated by different nutritions available in the culture medium. The present data will provide evidence for illustrating the regulatory roles of C/N on LMEs production under the co-cultures' circumstances.
