Evaluation of the properties on carrageenan bio-films with Chlorella vulgaris blending
Microalgae are multicellular species that exist individually or in groups which typically found in freshwater and marine systems and a good and highly potential source to produce bio-films. Bio-films with carrageenan possessed several drawbacks that needed to be encountered. The purpose of this stud...

Microalgae are multicellular species that exist individually or in groups which typically found in freshwater and marine systems and a good and highly potential source to produce bio-films. Bio-films with carrageenan possessed several drawbacks that needed to be encountered. The purpose of this study is to observe the number of microalgae cell influenced the performance of the bio-film obtained. Cultivation of free cell C. vulgaris microalgae was conducted in Bold’s Basal Medium (BBM) for 16 days. Growth curve of the C. vulgaris, lipid extraction and FAMES determination was conducted on the alternate days of cultivation. 3 mL of C. vulgaris microalgae was added into the formulation of carrageenan at the alternate days of cultivation (D-0, 4, 8, 12, and 16).
