Hydrogen production from cotton wastes by mean of dark fermentation

(Corresponding) Sołowski G., Konkol I., Shalaby M., (Corresponding) Cenian A.

Topic:

Energy technologies and sustainability

Dark fermentation of textile wastes is discussed in the paper. In the experiment were used cotton wastes. Before fermentation the cotton was hydrolyzed using 0.1 M of HCl. The inoculum was pretreated using heat shocked for 0.5 h at temperature of 105°C. The fermentation was carried out under...Read more
