Khan, Belas Ahmed and Wang, Jing and Warner, Philip and Wang, Hao (2015) Antibacterial properties of hemp hurd powder against E. coli. Journal of Applied Polymer Science, 132 (10). 41588/1-41588/6. ISSN 0021-8995

Abstract

Hemp (Cannabis sativa L.) is an eco-friendly and multifunctional plant. Hemp hurd is a by-product of hemp plant during hemp fiber separation. Although hemp hurd is repeatedly announced owing antibacterial activity, it has never been systematically investigated and reported. In this study, the antibacterial activity of hemp hurd powder against Escherichia coli is investigated. This article reveals antibacterial activity of hemp hurd where hemp hurd powder inhibits the growth of E. coli. Meanwhile, the self-contamination (forming during retting process) inside hemp hurd has dramatic impact on the antibacterial performance. To achieve better antibacterial activity, hemp hurd was heat treated to eliminate self-contaminations. The impact of the particle sizes and heat treatment on the antibacterial effectiveness was evaluated.
