A cyanobacterium transformed using a gene transfer vector. The gene transfer vector includes: a first homologous recombination region homologous to a 5′ side of a target DNA of the cyanobacterium; a second homologous recombination region homologous to a 3′ side of the target DNA; and a DNA fragment introduced into a portion sandwiched between the first homologous recombination region and the second homologous recombination region. A total length of the first homologous recombination region and the second homologous recombination region is 5 kbp or more. The cyanobacterium has a DNA fragment transferred between the 5′ side of the target DNA and the 3′ side of the target DNA.

Disclosed are techniques and systems for producing microbials having anaplerotic oils that are rich in odd-chain fatty acids, and other beneficial components, at higher concentrations than those present in other natural dietary sources of OCFA, at lower cost, and higher production yield. Further, disclosed are examples of incorporation of these higher concentration OCFA products into food for human and non-human animal consumption.

The present invention relates to a novel Chlamydomonas strain with an improved oil generation function, the strain of the present invention having useful mycological characteristics as a strain that provides a useful substance, such as a vegetable oil, in a microalga, as the strain has a fast cell growth speed and an excellent lipid generation function compared to conventional strains. In particular, the present invention can provide a vegetable oil with improved stability and a longer preservation period by containing, in a cell, a large amount of antioxidant pigments such as lutein and zeaxanthin, and can, thereby, be usefully used in industries such as food, medicine, cosmetics, etc., which utilize a vegetable oil.
