Morphological and biochemical characterization of isolated Aspergillus niger, Saccharomyces cerevisiae and Zymomonas mobilis from local indigenous sources

Abstract

Rapid global population growth has increased the demand for food and energy supply from cheap and readily available indigenous sources. Fungi and bacteria species were attempted to be isolated from indigenous sources using standard procedures. The bacteria isolated from Hibiscus sabdariffa drink and Citrus aurantium were characterized and identified as Saccharomyces cerevisiae and Zymomonas mobilis respectively while the isolated fungus from maize grains was characterized and identified as Aspergillus niger. These results show the enormous potential of these local substrates for bioethanol production.
