Efficacy of CKs on biotic production of bioethanol a renewable energy sources

Cytokinins (CKs) are plants harmones that promote cell growth and division, while there is limited direct research on cytokinins efficiency in bioethanol production. Cytokinins might influence microorganisms growth and fermentation efficiency. However, more research is needed to fully understand the efficacy of cytokinins (CKs) in bioethanol production. In the present communication the impact of some cytokinins, ie; zeatin (ZEA) on biotic production of bioethanol by some biothanol producing microorganisms such as Saccharomyces cerevisiae SS116 Zymomonas mobilis SS-325 and Aspergillus niger SS- 180 has been assessed. It has been found that the yeast strain of Saccharomyces cerevisiae SS-116 has been found most promising and best bioethanol producing strain of yeast microbe. The compound zeatin was found stimulatory and effective when 30% molasses solution (w/v) is allowed to ferment at pH 5.1, temperature 300C and incubation period of 50 hrs. It has been found that there is a gradual increase in the biotic production of bioethanol with stepping of compound zeatin till the maxium yield of bioethanol, ie; 8.75 mL/100 mL was obtained at its molar concentration of 6.0×10-5M which is 12.179% higher a comparison to control, ie; 7.80mL/100 mL.
