| Abstract |
Background. The article is aimed at studying the cytomorphological features of species Eremothecium ashbyi and Eremothecium gossypii - producers of riboflavin and essential oil.
Materials and methods. The material for research was 9 strains pertained to the genus Eremothecium. Micromorphology was studied in the native and dyed preparations by means of the microscope BIOMED-6.
Results. The complex of mutual features (dichotomous branching septate mycelium, conidia, vacuolization and thickening of hyphae, inclusions) and species characteristics (forms and sizes of sporangia, ascospores) were revealed. The ontogenetic changes of micromycete were considered. There was no significant difference of the growth rate, the phases and forms of alteration among species.
Conclusions. In the study of E. ashbyi and E. gossypii strains the distinctive characteristics and the complex of cytomorphological features were determined as specific for both species. The certain structures (sporangia, ascospores) have a differential-diagnostic meaning. The differences of rate and forms of ontogenetic changes were not revealed among species and strains.
