  • Heterogeneous photodegradation of methylene blue with iron and tea or coffee polyphenols in aqueous solutions

    Recently, we developed two new Fenton catalysts using iron (Fe) and spent tea leaves or coffee grounds as raw material. In this study, Fe-to-tea or Fe-to-coffee polyphenol complexes were successfully tested as heterogeneous photo-Fenton catalysts. The photodegradation efficiency of methylene blue solutions with Fe-to-polyphenol complexes was higher than that of homogeneous iron salts in the ...

  • Coffee cherry husk - a potential feed stock for alcohol production

    Coffee cherry husk (CCH) a toxic agro waste was tested for alcohol production by native yeast isolates. Out of five isolated yeasts, two produced acceptable amount of alcohol production from CCH extract. Pichia CJ isolated from rotten carrot and Clavispora CI isolated from coffee effluent produced maximum yield of 9.2 and 8.0%, respectively. Solid substrate fermentation (SSF) using CCH supported ...
