ABSTRACT

A comparative study of growth characteristics and peculiarities of glucose utilization by Fusarium poae and Penicillium funiculosum strains isolated from different habitats was conducted. It was found that F. poae and P. funiculosum strains differ as to their growth characteristics. Specific growth rate of endophytic strain F. poae was maximal (0.38 h(-1)), lower for plant pathogenic one (0.30 h(-1)) and the lowest for soil strain (0.18 hr(-1)). In contrast, the level of biomass accumulation was the highest for soil strain F. poae and minimal for plant pathogenic strain, endophytic strain took up an intermediate position. High economic coefficient was characteristic of soil strain and minimal of endophyte at medium biomass level and specific growth rate. In contrast to the strains of F. poae, the specific growth rate of soil strain of P. funiculosum was higher than that of endophyte one (0.35 and 0.24 h(-1), respectively). Biomass level of endophytic strain was significantly higher than that of the soil strain, and economic coefficient was 2.3 times higher for endophyte in comparison with soil strain.
