The invention relates to the field of biotechnology. A strain of microalgae Chlorella sp. VADA 2020 was isolated from water samples of Lake Tarmakul of the Chanovsky district of the Novosibirsk region and deposited in the Collection of Microalgae of the Plant Physiology Institute, RAS, under the registration number IPPAS C-2048. Available nutrient media are used for cultivating the strain. Namely, biomass with a protein content of 48.1 wt. %, and with a content of unsaturated and monounsaturated fatty acids in an amount of 59.1 wt. % (of the total content), is produced that can be used as raw materials to produce food additives. The invention makes it possible to produce biomass with a high content of protein and unsaturated fats, suitable for use for food purposes. 2 tbl, 2 ex.

The invention relates to biotechnology. The plankton strain of the unicellular green alga Chlorella vulgaris GKO, which has a thin cell wall, deposited in the Russian National Collection of Industrial Microorganisms under the registration number of VKPM A1-24. The strain VKPM A1-24 of the unicellular green alga Chlorella vulgaris can be used to produce food biomass intended for preparation of a beverage, concentrate, paste or dry powder. The invention makes it possible to shorten the period of cultivation of the biomass of unicellular algae.

This application describes consortium between fungi and algae, where the algae are incorporated within hyphae of the fungi. The fungi, the algae, or both can be modified to express heterologous lipid synthesizing enzymes. Incorporation of algae into fungi facilitates harvesting of the algae and products produced by the consortia. Such consortia are robust. For example, the fungi and algae can symbiotically provide nutrients to each other and are tolerant of environmental stresses.

A Labyrinthulid microorganism capable of producing a PUFA only through the elongase-desaturase pathway. A Labyrinthulid microorganism which has no ability of producing a PUFA through the endogenous PUFA-PKS pathway or has the ability at an extremely weak level and which has an ability of producing a PUFA through the endogenous elongase-desaturase pathway. The Labyrinthulid microorganism is a microorganism belonging to the genus Parietichytrium or Parietichytrium.

The present invention relates to microalgae with improved phototaxis and photosynthetic efficiency, and more particularly, to a microalgae PTS42 (KCTC18499P) mutant of Chlamydomonas reinhardtii and uses thereof. In the microalgae PTS42 according to the present invention of which photosensitivity and photosynthetic efficiency are improved due to excellent phototaxis, conversion of carbon dioxide into biomass is excellent as compared to a wild type strain and a maximum photosynthesis rate and lipid accumulation ability are also high, such that the microalgae PTS42 are useful as a photosynthetic strain for constructing a biofuel production process as well as an effect of decreasing carbon dioxide.

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.

Disclosed are novel strains of protists belonging to the Aurantiochytrium genus that allow the high yield production of lipids and carotenoids, in particular docosahexaenoic acid (DHA) and canthaxanthin and/or astaxanthin, in mixotrophic mode, in particular, using variable and/or discontinuous provision of light, in particular in the form of flashes.

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

A green alga variant having a dual-specificity tyrosine-phosphorylation regulated protein kinase activity that is reduced compared to a dual-specificity tyrosine-phosphorylation regulated protein kinase activity of a parental strain is provided. The green alga variant increases a total amount of a lipid production per unit time and per unit culture area compared to a total amount of a lipid production of the parental strain. A dual-specificity tyrosine-phosphorylation regulated protein kinase of the parental strain is a protein having an amino acid sequence with at least 50% sequence identity with the amino acid sequence of an active site and a substrate recognition site of SEQ ID NO: 4 and having the dual-specificity tyrosine-phosphorylation regulated protein kinase activity.
