Identification of yeasts isolated from Nigerian sugar cane peels

A pilot study was carried out to determine the yeast species associated with sugar cane peels recovered from three separate dumping sites found in Ojo, a typical market town in Nigeria. Species identities were determined by 26S ribosomal DNA (rDNA) sequencing. By using this method, a total of 6 different yeasts were identified, with Candida tropicalis, a recognised human yeast pathogen, being the species most frequently isolated from these dumping sites. The implications of this and other findings of the study, the apparent first of its kind, are discussed in detail.
