Molecular Characterisation and Identification of Three Mushrooms Found in the Niger Delta Region
Annual Research & Review in Biology,
Mushrooms are a group of fungi that are diverse and in the Niger Delta region; there are various species, some of which share similar morphological features. Over the years, mushrooms have been put to several important uses ranging from food, nutraceuticals, feed for livestock, and more recently bioremediation, hence, the need for an accurate approach of identification is eminent. This study aims to identify three mushroom samples with the potential for crude oil degradation using molecular tools. The molecular identification of the mushrooms was carried out with the ITS (Internal Transcribed Spacer) region to analyze their genetic diversity. The three mushroom samples were identified as Pleurotus ostreatus, Pleurotus floridanus and Lentinus squarrosulus. The blast results showed 86.0%, 97.9%, and 88.4% for Pleurotus ostreatus, Pleurotus floridanus and Lentinus squarrosulus respectively for sequence similarity. The samples were assigned unique accession numbers on GenBank The use of molecular characterization gives reliable results to the species level. The results from this study have increased the database of Pleurotus and Lentinus DNA and serve as a basis for the identification of unidentified species by comparing their PCR amplified sequences with ITS primers.
