Role Of Microalgal Organic Matterderived Biocoating Towards Cell Deposition In Natural Biofilm Formation

Biofilm-based algal cultivation is gaining popularity as a viable platform for algal production, wastewater treatment and as a feedstock source for microalgae-based biorefinery initiatives. However, the interaction between cells and biocoatings are poorly understood. In this paper, the degree of...
