Increased consumption of fossil fuels is an emerging problem.
Scientists look for the existence of other alternatives to fossil fuels, including so-called renewable energy.
Accordingly, we report the production of bio-ethanol from the remnants of castor oil bean seed cake (CBC) by the carboxymethylcellulase enzyme (CMCase).
A bacterial strain isolated from rice straw showing higher CMCase activity was identified.
The 16S rRNA result showed a 93 % homology with the 16SrRNA gene sequences of Pseudomonas poae RE ⁄ 1-1-14, the strain was identified as Pseudomonas poae AB3.
In addition, our results showed that the highest enzyme activity was achieved after 48 h and inoculum size of 3.7 _ 105 CFU.
The optimum temperature, pH and Carboxymethylcellulose (CMC) concentration for the highest enzyme activity was 25 _C, pH 7 and 10 g/l respectively.
Furthermore, The CMCase was purified by ammonium sulphate at a concentration of 60 %.
The SDS-PAGE of the purified enzyme showed a molecular weight of 88 kDa.
Additionally, the (CBC) was hydrolyzed by the purified CMCase at the enzyme optimum conditions.
The results showed the liberation of 5.2 g / L of reducing sugar by using dinitrosalicylic acid (DNS) assay.
Finally, the total sugar produces 35 g / L after 48 h when Saccharomyces cerevisiae was used as a fermentation agent.
Hence for the first time, we have been successfully able to produce bioethanol from CBC with CMCase of Pseudomonas poae.
