A catalyst material for enhancing hydrogen and oxygen production includes algae-derived carbon scaffolds; and catalyst components coupled to the algae-derived carbon scaffolds. The catalyst material has excellent oxygen evolution reaction (OER) performance superior to that of a benchmark OER catalyst Ir/C.

The invention relates to a new process for extracting and purifying phycocyanins produced by fermenting microalgae, in particular produced by Galdieria sulphuraria, by means of selective precipitation.

The present invention provides a microalgae product and a production method for the microalgae product. In one embodiment, the present invention provides a method for treating microalgae without an increase in pheophorbide. By this method, provided is a safe microalgae product having reduced pheophorbide. Such a microalgae product provides various healthy, nutritional, and/or cosmetic effects. The present invention also provides a culturing device that enables high-concentration culturing with less bacterial contamination, and thereby enables highly useful culturing of microalgae.

The present application relates to a method for producing biomass comprising protein and omega-3 fatty acids from single microalgae, and biomass produced thereby, the method for producing biomass according to one embodiment supplying the cultivation stage continuously with a nitrogen source to allow producing single microalgae-derived biomass having high protein and omega-3 fatty acid content, and as such, biomass produced thereby can be effectively used as the single microorganism source of protein and omega-3 fatty acids.

The present invention is directed to isolated microorganisms as well as strains and mutants thereof, biomasses, microbial oils, compositions, and cultures; methods of producing the microbial oils, biomasses, and mutants; and methods of using the isolated microorganisms, biomasses, and microbial oils.

The present invention discloses a LC-PUFA biomass composition which has reduced self-heating propensity and thus requires a lessened packing requirement for shipment. The invention also discloses methods for making such biomass composition.

A microorganism having at least one SPX gene encoding SPX protein responsive to phosphorus deficiency, and characterized in that a function of the SPX protein is decreased or lost by introducing gene mutation into the SPX gene.

[Problem] The purpose of the present invention is to provide a method for collecting seawater that contains plankton and generating DHMBA (dba), which is an antioxidant, from the plankton contained in the seawater. [Solution] The present invention is characterized in that: collected seawater containing plankton is filtered using a filter, the cell contents are removed from the plankton remaining on the filter, the removed cell contents are subsequently heated, and 3,5-dihydroxy-4-methoxybenzyl alcohol is produced from the heated product; and the plankton are assumed to be diatoms.

The present application discloses a method of culturing a Euglena sp. microorganism, Schizochytrium sp. microorganism, or a Chlorella sp. microorganism comprising culturing the microorganism in a hybrid culture media; maintaining the microorganism heterotrophically in an environment substantially free from light; wherein the hybrid culture media comprises a carbohydrate; and wherein the hybrid culture media comprises fresh media and recycled culture media. The present application also discloses a hybrid culture media.

The disclosure pertains to a method for the production of triacylglycerides (TAGs or Triacylglyerols) and fatty acids by the recombinant expression of a Δ11 fatty acid desaturase in protists.
