Abstract
An ecological study of algae at River Ginzo in Katsina town was carried out for six weeks at three different sites. In this study, various strains of native microalgae were identified and isolated. The water's physicochemical properties were analyzed at Kofar Marusa, Kofar Sauri, and Kofar Durbi of River Ginzo in Katsina State. The physicochemical parameters studied showed temperature and pH range of 28oC to 31oC and 6.42 to 7.36. A total of eighteen (18) algal species were identified, out of which Ten (10) species belong to the Class Chlorophyceae with Spirogyra species having the highest cell counts, five (5) species belong to the Class Cyanophyceae with Oscillatoria species having the highest cell count and three (3) species belong to the Class Bacillariophyceae with Nitzchia spp having the highest cell counts. Among the isolates, Chlorella species showed an increased growth rate with higher biomass productivity of (88.67±2.57) X 104 (cell/ml) after six days of incubation. The results showed that Chlorella, Spirogyra, and Oocystis species could be a possible candidate species for producing oils for sustainable biodiesel production, based on their high growth rate and presence in all the locations.
Highlights
An ecological study of algae at River Ginzo in Katsina town was carried out for six weeks at three different sites
Biomass obtained from microalgae is considered to be a good source for the production of fuels when compared to other sources of renewable biomass; the microalgae oil yield is 15-300 times more than different traditional crops base on the area as well as the contents of the oil which ranges from 20-50% to other competitors
Microalgae belonging to Nannochloropsis, Neochloris Chlorella, Dunaliella, Nannochloris, Scenedesmus, and Porphyridium, contains 20–50% of lipids by weight, making them desirable for biodiesel production (Mata et al, 2010)
Summary
An ecological study of algae at River Ginzo in Katsina town was carried out for six weeks at three different sites. Chlorella species showed an increased growth rate with higher biomass productivity of (88.67±2.57) X 104(cell/ml) after six days of incubation. The results showed that Chlorella, Spirogyra, and Oocystis species could be a possible candidate species for producing oils for sustainable biodiesel production, based on their high growth rate and presence in all the locations. Trying to identify the algal species that grow best under local environmental conditions and using those species to assemble a microalgal community suitable for different growth environments is a good strategy. This research work aimed to isolate, identify, and study the influence of enriched culture media on biomass productivity of selected microalgae strains found in the natural habits of Katsina
