The present invention belongs to the field of biotechnology, and particularly relates to a Euglena culture medium and an application thereof. The Euglena culture medium includes the following components: NH.sub.4Cl, KH.sub.2PO.sub.4, MgSO.sub.4.7H.sub.2O, CaCl.sub.2.2H.sub.2O, Na.sub.2EDTA.2H.sub.2O, Fe.sub.2(SO.sub.4).sub.3, CuSO.sub.4.5H.sub.2O, ZnSO.sub.4.7H.sub.2O, Co.(NH.sub.3).H.sub.2O, MnCl.sub.2.4H.sub.2O, vitamin B.sub.1 and vitamin B.sub.12. The pH is adjusted based on the Euglena culture medium of the present invention to achieve the purpose of preconcentrating Euglena cells. In the present invention, the Euglena cells are less ruptured, which improves the concentration efficiency of Euglena cells and reduces the treatment cost.

The present invention relates to, inter alia, compositions and methods, including therapeutic alkaline phosphatases that find use in the treatment of disease, such as microbiome-related diseases. In part, the invention provides, in various embodiments, methods of manufacturing therapeutic alkaline phosphatases.

Growth medium are disclosed for use in fermenting a marine microorganism. The medium comprise Potassium, Calcium, Strontium, Borate and Fluoride at specific concentrations. Alternatively, the growth medium comprises cobalt at specified concentrations or comprises vitamin B.sub.12 at specified concentrations. Methods of producing certain desired compound by fermentation of a marine microorganism are also disclosed.

Disclosed is a composition for selective enrichment of progressively motile non-fragmented/intact DNA sperms during swim-up of semen sample comprising combination of electrolytes, a mix of excipients, polyyvinylpyrrolidone, recombinant human serum albumin or bovine serum albumin. A method of selective enrichment of DNA-intact sperms using the compositions of the present invention is also disclosed. The DNA fragmentation index of the swim-up sperms are less than the DNA fragmentation index of the neat samples. The media compositions of the present invention are applicable for enrichment of non-fragmented/intact DNA sperms for therapeutic purposes in the field of assisted reproductive technologies.

Provided herein are methods and compositions comprising a bacterium or a metabolite thereof for enhancing mitochondrial and/or peroxisomal function.

The present invention relates to a mesenchymal stem cell storing or transport formulation, a method of preparing the mesenchymal stem cell toring or transport formulation as well as to methods of using the mesenchymal stem cell storing or transport formulation. Such methods include a method of transporting mesenchymal stem cells in this storing or transport formulation as well as a method of treating a subject having a disease, the method comprising topically administering mesenchymal stem cells that have been stored or transported in this storing or transport formulation. Also concerned is a unit dosage of the mesenchymal stem cells.

Methods and compositions for modifying glycans (e.g., glycans expressed on the surface of live cells or cell particles) are provided herein.

The present invention discloses formulation of a serum-free medium used for human pluripotent stem cells, which comprises the following raw materials: inorganic salt components, organic components, amino acids and amino acid salts, energy substances and metabolic intermediates, vitamins and antioxidants, proteins and polypeptides, trace elements and chromogenic substances; while the culture process comprises the following steps: selecting a basic formulation, performing combination screening, identifying and evaluating results, and testing a new formulation of culture; and proportioning according to the following methods: adding aforesaid raw materials into 950 ml of water for injection, stirring gently until dissolved, and finally adding 2.438 g of sodium bicarbonate, and stirring gently until dissolved, and then adding 1 liter of water for injection, adjusting the pH to the desired value with 1 mol/L sodium hydroxide solution or 1 mol/L hydrochloric acid solution, finally filtering sterilized with 0.1 m diameter filter under positive pressure, and storing the medium solution in dark place at 2 C.-8 C., the invention solves the problem of high cost of domestic import of serum-free formulation.

A method to improve the production of acetyl-CoA-derived biochemicals by overexpression of an acetyl-coenzyme A synthetase or acetate-CoA ligase from naturally acetate-utilizing organisms with or without an added acetate transporter. The production of free fatty acid and its derivatives from renewable carbon source was used as a non-limiting example. Using this approach, the production of free fatty acids with yield close to the maximum theoretical yield at high titer can be achieved. As such, this invention will provide the necessary framework to produce many other products sharing or branching out from the fatty acid synthesis pathway economically. These products include hydrocarbons, fatty alcohols, hydroxy fatty acids, dicarboxylic acids, fatty acid esters, etc.

The present disclosure provides methods and compositions of matter directed to removing heavy metals, such as lead, from aqueous solutions by bioremediation. The methods use bacteria, which thrive in the presence of heavy metals to precipitate the heavy metals from the aqueous solution. In some embodiments, the bacteria comprise Bacillus licheniformis.
