Unsaturated Fatty Acids Biosynthesis from Schizochytrium

Schizochytrium is a fungus-like heterotrophic unicellular marine eukaryote that is ubiquitous in coastal marine ecosystems worldwide. They have attracted attention due to their ability to produce high levels of long-chain polyunsaturated fatty acids (LC-PUFAs), especially docosahexaenoic acid (DHA, C22:6n3). Schizochytrium limacinum SR21 has been extensively characterized to produce DHA. The DHA content of total fatty acids in Schizochytrium may approach 40%. During microbial fermentation for the production of lipids and polyunsaturated fatty acids, the generated ROS and reactive aldehydes impair cellular metabolism and inhibit lipid productivity. However, PUFA production in Schizochytrium is attractive because these microorganisms possess the necessary biosynthetic machinery and, unlike field plants, can grow rapidly using inexpensive media under controlled conditions in bioreactors. Fermentation technology allows year-round production. Schizochytrium and other thraustochytrids in unsaturated fatty acids production do not require light. CD BioSciences' staff have many years of experience in marine unsaturated fatty acids biosynthesis process design and optimization. Our labs focus on the efficient delivery of science, compliance, customer service and data. All teams work hard to provide exceptional service, delivering data that fits your schedule.

Our Services

CD BioSciences provides high quality unsaturated fatty acid biosynthesis services. Our excellent technology can realize microbial fermentation, process design, yield improvement services, and solve all difficulties encountered in research for customers.

  • Unsaturated Fatty acid Biosynthesis in Schizochytrium
    Commercial fermentation requires competent microbial strains. Acceptable strains must have high productivity. CD BioSciences improves productivity by mutagenizing Schizochytrium strains. CD BioSciences utilizes metabolic engineering and genetic engineering tools to modify genes associated with target enzyme and regulatory protein expression to enhance unsaturated fatty acid biosynthesis
  • Fermentation Process Design
    Our scientists use possible fermentor operating schemes including batch, fed-batch, repeated fed-batch, and continuous culture.
  • Fermentation Process Improvement
    CD BioSciences controls the quality and composition of media and inoculum in fermentation process optimization. Batch and fed-batch operations are often preferred in commercial large-scale fermentations at CD BioSciences.
    • Use of chemical modulators
    • Coculture and sonication
