Ariana Budhihartanto
Abstract:Spent coffee grounds or coffee waste pose a growing environmental problem as it can harm the ecosystem by releasing greenhouse gases into the atmosphere during their decomposition process [1]. On the other hand, spent coffee ground extracts have been shown to contain polyphenols, trigonelline, phenolic acids, and melanoidins which show strong antibacterial activity toward Gram+ bacteria and yeast [2]. Given its activity towards Gram+ bacteria, this study seeks to find an alternative use of spent coffee grounds… Show more
