Influence Of Multi-Walled Carbon Nanotubes (Mwcnts) On Viability Of Paecilomyces Fumosoroseus (Wise) Brown & Smith (Deuteromycotina: Hyphomycetes) Fungus Spore

The study aimed at testing the influence of pristine multi-walled carbon (MWCNTs) and carboxyl (MWCNT(COOH)) nanotubes on spores of entomopathogenic Paecilomyces fumosoroseus fungus. The effect of the nanotubes on the fungus linear growth, biomass increment and sporulation was determined. The character of linear growth of P. fumosoroseus mycelium obtained from the spores contacted with MWCNTs was different in comparison with the control. Pristine carbon nanotubes significantly stimulated P. fumosoroseus mycelium linear growth and limited its sporulation in comparison with the control. Carboxylation changed the influence of carbon nanotubes on the spores of the tested fungus. The activity of MWCNT(COOH) was definitely weaker and the obtained linear growth and sporulation did not differ significantly from the control. No apparent effect of MWCNTs on the increment of P. fumosoroseus biomass was found.
