Culturing S. glucoliberatum PABB004 under conditions effective for the S. glucoliberatum PABB004 to secrete simple sugars into culture medium. In one or more embodiments, the conditions include a pH of 6.0 to 8.5. In some cases, the culture can include a second organism. A co-culture includes S. glucoliberatum PABB004 and a second organism, wherein the co-culture has a pH of 6.0 or greater. In one or more embodiments, the second organism is selected to produce a product of interest such as, for example, ethanol.

Microalgal mutant to produce high-value essential LCPUFA oils including eicosadienoic acid (EDA), dihomo-γ-linoleic acid (DGLA), arachidonic acid (ARA), and eicosapentaenoic acid (EPA) in various ratios in are provided.

The present disclosure relates to the fields of biotechnology, molecular biology and genetic engineering. In particular, the present disclosure relates to a genetically modified alga comprising a recombinant cytochrome c6 gene, methods of producing the same and applications thereof. The present disclosure also relates to a codon optimised nucleic acid sequence encoding a cytochrome c6 polypeptide, expression cassette, vectors and host cell thereof. In an embodiment, the present disclosure also relates to a method of increasing biomass and photosynthetic efficiency of algae.

Disclosed is a method for culturing Haematococcus pluvialis containing a large amount of astaxanthin. According to one embodiment, the method includes culturing Haematococcus pluvialis under autotrophic conditions to prepare a culture containing cysts in which astaxanthin is accumulated and adding a nitrogen source to the culture to induce germination of the cysts.

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.

Docosahexaenoic acid-containing oil containing docosahexaenoic acid in a concentration of 40 wt. % or more of the total weight of fatty acids in the oil, and having an endothermic peak temperature determined by differential scanning calorimetry (DSC) of 15° C. or lower; a biomass including the same; and a method for producing docosahexaenoic acid-containing oil including obtaining a biomass by culturing microorganisms of the genus Aurantiochytrium capable of producing this docosahexaenoic acid-containing oil, recovering the biomass after culture, and extracting the oil from the biomass after recovery.

The present invention relates to novel microalgae with high productivity of loliolide, in which the Scenedesmus sp. HS4 of the present invention can be used as a biological resource to produce loliolide due to its high biomass productivity and high loliolide content, and can be used as a pharmaceutical composition or cosmetic composition which requires loliolide derived from Scenedesmus sp. HS4.

Water-responsive actuators and methods for creating water responsive actuators are disclosed. In some embodiments, the disclosed subject matter includes a first layer, for example a plastic tape, and a second layer, for example bacterial spores and cured adhesive. The second layer can be created in a pattern. The pattern can include joints, which can contract when exposed to dry air and can thereby bend the actuator, and can expand when exposed to humid air and thereby return the actuator its original position.

The present invention relates to a novel spirulina strain having a linear shape, which spirulina strain can be used to achieve a harvest of spirulina strain with high yield.
