ISOLATION AND IDENTIFICATION OF STARCH HYDROLYZING ASPERGILLUS SPECIES FROM THE SOIL IN ISA MUSTAPHA AGWAI I POLYTECHNIC (IMAP), LAFIA.
Abstract
Aspergillus species are utilized in the fermentation industry. The investigation is
aimed to find out the fungal diversity, also to isolate and identify the Aspergillus
species in the soil samples collected from the soil in Isa Mustapha Agwai I
Polytechnic Lafia. For this isolation and identification, plating, pure culturing,
incubating, staining, and inoculating such techniques are used. The mycelia and
cytoplasm are stained using Lacto phenol and cotton blue (provides light blue
background). The stained specimens are observed under the microscope for
identification and photographs are taken. Among the identified species the
Keratinophilic fungi Aspergillus Niger is found in maximum numbers in the
campus and followed by others. All the isolates are identified with standard key
and microbial expert
