発明の名称 (英語) ALGA IN WHICH PRODUCTION OF PHOTOSYNTHETIC PRODUCTS IS IMPROVED, AND USE FOR SAID ALGA UPDATE 新技術説明会
発明の概要(英語) Provided are an alga in which the production of photosynthetic products is improved, and the use for said alga. The alga of the present invention has an increased glutathione concentration in the chloroplast. Moreover, the biomass production method of the present invention produces biomass by using the alga of the present invention or alga produced by means of the alga production method of the present invention.
従来技術、競合技術の概要(英語) BACKGROUND ART
As fuel alternatives to fossil fuels, biomass-derived fuel, so-called bio fuel (for example, bioethanol, biodiesel and the like) is expected.
A raw material of biomass (for example, starch) or sugars such as oil or fat biomass, plant is produced by performing photosynthesis. For this reason, and actively photosynthesis, sugars oils or fats such as plants that have the ability to accumulate inside the cell, can be utilized as the biomass producing means. The current, in order to produce biomass, mainly, corn or soybean used. Corn or soybean, are also used as a food or feed. For this reason, doubled significantly caused by the production of biomass, the price of the food and feed has been regarded as a problem.
Therefore, as an alternative to corn or soybean biomass production, biomass production by algae has attracted attention (for example, see Patent Document 1 and Patent Document 2). Biomass production by the algae is, not in conflict with the feed or food, can be mass proliferation, and the like advantages.
For example, for a kind of algae Chlamydomonas, cell wall deficient variants or cell wall becomes thinner variants (cw15, cw92 or the like) are known. These variants can, when introduced into cells from the outside DNA of convenient nature, has been widely used in gene transfer experiments. The fragile nature of the cells, facilitates recovery of cellular contents in the sense that they improve the productivity of the biomass, using these mutants have been reported for biomass production. For example, Patent Document 3 is, in the cell wall deficient Chlamydomonas mutants of technology for the production of fats and oils described. In addition, the non-patent document 1, in addition to the cell wall mutation (cw15), of the synthetic gene in starch Chlamydomonas vacancy, the oil droplets made from fats and oils can be discharged to the outside of the cells have been reported. Non-patent document 2 is, in the cell wall of the variant (cw15) Chlamydomonas, starch synthesis to disrupt a gene by increasing the productivity of the fat have been reported. In addition, as a report regarding mutations Chlamydomonas cell wall, non-patent document 3 is known.
In addition, as a material which is a kind of algae Chlorella, produced outside of the cell to release the starch, followed by ethanol fermentation techniques have been reported (patent document 4).
