How Do Genus Fungi Win a Nutritional Competition Battle against Soft Fruit Pathogens? A Report on Niche Overlap Nutritional Potentiates.

We present a case study report into nutritional competition between spp. isolated from wild raspberries and fungal phytopathogenic isolates ( sp., sp., sp. and sp.), which infect soft fruit ecological plantations. The competition was evaluated on the basis of nutritional potentiates. Namely, these were consumption and growth, calculated on the basis of substrate utilization located on Biolog Filamentous Fungi (FF) plates. The niche size, total niche overlap and spp. competitiveness indices along with the occurrence of a stressful metabolic situation towards substrates highlighted the unfolding step-by-step approach. Therefore, the spp. and pathogen niche characteristics were provided. As a result, the substrates in the presence of which spp. nutritionally outcompete pathogens were denoted. These were adonitol, D-arabitol, i-erythritol, glycerol, D-mannitol and D-sorbitol. These substrates may serve as additives in biopreparations of spp. dedicated to plantations contaminated by phytopathogens of the genera sp., sp., sp. and sp.
