Abstract:
Microorganisms from the rhizoosphere soil was isolated from different
potato fields of Bangladesh. Seventeen soil samples were analyzed for the
incidence of microorganisms from potato field soils. A total of seven fungal
species, one bacterium species and one nematode species were characterized
using various isolation and identification methods. The predominant fungi
isolated include among others; Alternaria solani, Aspergillus niger,
Penicillium sp., Rhizopus stolonifer, Bipolaris sp., Phytophthora infestans ,
Fusarium oxysporum, Ralstonia solanacearum and Meloidogyne sp.. And
individual colonies of fungi, bacteria and nematode were counted from
media and compared their presence in soil in respect of different locations of
potato fields. The present study aimed to find out the fungal diversity and
this was the first reported examination of the microbiological diversity of
soil microorganisms of some selected potato fields in Bangladesh.
