“…In this study, we observed that most of the in-vitro interactions among and between white rot as well as brown rot fungi either led to complete replacement (grade 3) or deadlock (grade 4). Similar observations during the interaction process have been inferred by Owens et al ( 1994 ). Grade 5 type of interaction where the hyphal growth of the two confronting fungi inhibits at a distance without any contact has not been observed in the study.…”

In nature, species interacts/competes with one other within their surrounding for food and space and the type of interactions are unique to each species. The interacting partners secrete different metabolites, which may have high importance in human welfare. Fungal-fungal interactions are complex mechanisms that need better understanding. Here, 14 fungal isolates were facilitated in 105 possible combinations to interact on potato dextrose agar. Morphologically, no changes were observed when the same fungal isolates were allowed to interact within them. However, 10 interactions between different fungal isolates showed mutual replacement with each fungus; capturing territory from the other. Contrastingly, 35 interactions resulted into complete replacement as one of the fungi was inhibited by rapid growth of the other fungus. In 46 interactions, formation of barrage was observed leading to deadlock type of interaction wherein both fungi have restricted growth. To study in details about the barrage formation, two fungal interactions were taken (i) T. coccinea vs. L. lactinea and (ii) T. coccinea vs. T. versicolor. Microscopic changes in the hyphal growth during interaction were observed. There was significant increase in the enzymatic activities including cellulase, xylanase and chitinase during in-vitro fungal-fungal interaction, suggesting the importance of such interactions for commercial enzyme production.

“…Interactions are crucial determinants of fungal community development, and affect decay rate and carbon turnover in woodland ecosystems (Owens et al, 1994;Boddy, 2000). There are two main interaction outcomes: replacement occurs when one fungus gains the territory of another; deadlock occurs when neither fungus gains headway.…”

“…Therefore, ecological interactions contribute significantly to fungal communities' dynamic and structure. Thus, it is possible to take advantage of these interactions to simulate the natural environment of these microorganisms, positively interfering with the biodelignification of the colonized substrate (Boddy et al, 1989;Owens et al, 1994).…”

The lignocellulosic biomass is a highly abundant and renewable resource. However, its exploitation is limited by the recalcitrance of the lignin present in the plant cellwall. In the last three decades, fungal co-cultures have increasingly been applied to overcome lignin recalcitrance by enhancing the production of ligninolytic enzymes through microbial interactions. In this paper, we systematically compile studies on fungal co-cultures used in the degradation of lignin-containing substrates to clarify the advantages and limitations of this type of culture. Based on their different delignification rate potentials, co-cultures can be classified into synergistic, antagonistic, and neutral. Co-cultivation results are generally related to the balance or imbalance of antagonistic and synergistic effects arising from the specific compatibility between the species during the interaction. It is well known that the paired species and the microenvironmental system conditions are responsible for the reported degradations,however, the mechanisms underlying these interactions remain poorly understood. In conclusion, literature results demonstrate the promising application of fungalco-cultures in biotechnological sectors to improve the degradation of lignin and its derivatives, through their better understanding of the efficient exploitation ofbiological resources on ecological and industrial scales.
