While green algae are expected to serve as raw materials of biomass fuels, they are damaged by high-intensity light when subjected to mass-culture outdoors in summer, and biomass productivity is deteriorated as a consequence. In order to overcome such a drawback, the present invention provides a high-intensity light resistant green algae mutant that can be subjected to outdoor culture in summer. Specifically, the present invention relates to such green algae mutant, wherein functions or expression levels of a protein having a response regulatory domain at the N-terminus and a WD40 domain at the C-terminus are lower than those in a wild-type strain, and wherein said green algae mutant grows faster than a wild-type strain when cultured at a light intensity of 1,000, 1,500, or 2,000 &#x3bc;mol photons msmeasured as photosynthetically active radiation (PAR).

Green algae mutant exhibiting resistance to intense light, and use thereof

A culture method for microalgae that cultures unicellular green microalgae belonging to the genusand groups of organisms closely related thereto, or the Watanabea clade, in an open outdoor culture system using broth having a pH of 4 or lower. A culture method for microalgae that cultures microalgae of the genusand groups of organisms closely related thereto, or, in an open outdoor culture system using broth having a pH of 4 or lower containing ammonia nitrogen.

A noble metal adsorption agent includes algae or residue of algae having an amino group as a functional group. A noble metal is retrieved by a method including: adsorbing the noble metal on the noble metal adsorption agent; and retrieving the noble metal. The noble metal is solved in a liquid. Thus, by using the noble metal adsorption agent, the noble metal is selectively retrieved.

The object of the present invention is to provide a method for aggregating and separating algae dispersed in a liquid efficiently. According to the present invention, a method for aggregating and separating algae dispersed in a liquid, which comprises adding an alkaline inorganic aggregating agent to the liquid at pH of 2.0 to 4.0 in which algae are dispersed, followed by adding a cationic polymer aggregating agent, is provided. Further, according to the present invention, a method for producing biofuel utilizing algae is provided.

An adsorbent contains a carbohydrate having an ether linkage. Alternatively, an adsorbent contains a carbohydrate having a cross-linkage formation produced by a dehydration reaction using a strong acid. In collection of a precious metal using the adsorbent, the adsorbent selectively adsorbs a precious metal dissolved in a solution.
