Abstract
ABSTRACT Docosahexaenoic acid (DHA) is one of the essential polyunsaturated fatty acids required for human health. Recently Schizochytrium sp. has become an ideal microorganism for the industrial production of DHA due to its advantages of easy cultivation, fast growth rate, simple fatty acid composition and high DHA content. This review focuses on the new progress about DHA extraction from Schizochytrium sp. Current efforts about the screening and improvement of Schizochytrium sp., optimization of the fermentation, lipid extraction and DHA purification were discussed. Meanwhile, the different routes involved in DHA synthesis in Schizochytrium sp. were described. At last, we propose that breeding of stable high DHA-yielding Schizochytrium sp., exploring low-cost and high-efficiency fermentation substrates, and clarifying DHA synthesis pathways are the future research priorities.
期刊介绍：
Food Biotechnology is an international, peer-reviewed journal that is focused on current and emerging developments and applications of modern genetics, enzymatic, metabolic and systems-based biochemical processes in food and food-related biological systems. The goal is to help produce and improve foods, food ingredients, and functional foods at the processing stage and beyond agricultural production.
Other areas of strong interest are microbial and fermentation-based metabolic processing to improve foods, food microbiomes for health, metabolic basis for food ingredients with health benefits, molecular and metabolic approaches to functional foods, and biochemical processes for food waste remediation. In addition, articles addressing the topics of modern molecular, metabolic and biochemical approaches to improving food safety and quality are also published.
Researchers in agriculture, food science and nutrition, including food and biotechnology consultants around the world will benefit from the research published in Food Biotechnology. The published research and reviews can be utilized to further educational and research programs and may also be applied to food quality and value added processing challenges, which are continuously evolving and expanding based upon the peer reviewed research conducted and published in the journal.
