Development of New Marine Proteins

Marine organisms are increasingly scrutinized due to their status as significant producers of bioactive peptides and enzymes. The majority of bioactive compounds derived from marine environments are procured from commensal microorganisms. Within this realm of microorganisms, bacteria hold paramount importance as a source of bioactive peptides, extracted from intricate gene networks expressed under marine conditions through metagenomic studies. A plethora of peptides have exhibited biotechnological prowess, encompassing antibacterial, antitumor, antihypertensive, anticoagulant, antifouling, and antioxidant activities, thereby rendering them valuable for employment in the pharmaceutical and food industries. Marine microbial enzymes manifest an extensive array of applications within the bioindustry. Microorganisms retrieved from extreme marine settings have yielded numerous enzymes, including amylases, caseinases, lipases, gelatinases, and DNases. These enzymes exhibit thermostability and the capacity to endure disparate pH ranges and other demanding conditions essential for industrial applications.

CD BioSciences is a marine biology company dedicated to bringing you best-in-class enzyme and peptide technologies. We use the most refined fermentation technology to develop highly efficient enzymes and peptides, providing reliable solutions for various industrial applications.
