Marine microalgae Chlorella vulgaris, Spirulina platensis, Navicula incerta and Pavalova lutheri are fewpotential algal species that could be used to extract biologically active peptides with significant therapeutic potentials.
P. lutheri is a widely studied marine microalga for extraction of bioactive peptides. Research findings demonstrate that microbial fermentation of P. lutheri bio-mass could be used to obtain small peptide which has high anti-oxidative activity.
Further, Himaya et al. (2013) reported that active peptide isolated from microbial hydrolysates of Chlamydomonas sp. potently suppresses H. pylori-induced carcinogenesis.
In addition, peptide isolated from enzymatic hydrolysis of N. incerta
has shown protective activity against ethanol-induced hepatotoxicity.
