摘要:
La présente invention concerne un procédé de culture in vitro en milieu de culture acellulaire, de bactérie dont la croissance est sensible à la teneur en oxygène, la croissance optimale de la dite bactérie exigeant une atmosphère d'incubation à teneur en oxygène relativement réduite par rapport à la teneur en oxygène de l'air, ladite bactérie étant choisie parmi les bactéries anaérobies, caractérisé en ce que l'on ajoute dans le dit milieu de culture acellulaire un composé antioxydant choisi de préférence parmi l'acide ascorbique, le glutathion et l'hydrosulfure de sodium, et l'on cultive la dite bactérie dans ledit milieu de culture en présence d'oxygène.
摘要:
The present invention relates to methods and compositions for modulating glycosylation of recombinant proteins expressed by mammalian host cells during the cell culture process. Also disclosed are methods of culturing a host cell expressing a recombinant protein in a cell culture medium comprising a disaccharide or a trisaccharide, while keeping the osmolality constant.
摘要:
A method for enhancing yeast growth for bioproduct production is described. A method for fermentative bioproduct production also is provided. A nutrient composition used in the methods also is described. A liquid mixture containing the nutrient composition, yeast culture (or fungi, algae, or bacteria culture), and sugars also is provided.
摘要:
The present description is related to the field of cultivating algae. It introduces a method of cultivating algae by depleting the culture of an inorganic nutrient and exposing the alga to high intensity light to obtain algal cell mass having enriched lipid content and reduced chlorophyll content.
摘要:
Disclosed herein are methods of use of methylsulfonylmethane (MSM) to modulate microbial activity, such as to enhance or inhibit the activity of microorganisms. In one example, MSM (such as about 0.5% to 5% MSM) is used to enhance fermentation efficiency, such as to enhance fermentation efficiency associated with the production of beer, cider, wine, a biofuel, dairy product or any combination thereof. Also disclosed are in vitro methods for enhancing the growth of one or more probiotic microorganisms and methods of enhancing growth of a microorganism in a diagnostic test sample. Methods of inhibiting microbial activity are also disclosed. In one particular example, a method of inhibiting microbial activity includes selecting a medium that is susceptible to H1N1 influenza contamination; and contacting the medium with MSM at a concentration of about 10% to about 16% of weight by volume, thereby inhibiting H1N1 influenza microbial activity.
摘要:
The present invention relates to the regulation of a toxin and/or antitoxin genes in a genetically engineered microorganism, such as cyanobacterial or eukaryotic algal strains, in particular for preventing unintentional and/or uncontrolled spread of the microorganisms. The present invention also includes methods of controlling the growth and/or survival of the engineered microorganism
摘要:
The present invention is directed to methods for inducing desired activity in enzymes or microorganisms capable of producing the enzymes. The invention is further directed to methods of stabilizing activity in microorganisms. In specific embodiments, the invention provides methods for inducing and stabilizing nitrile hydratase activity, amidase activity, and asparaginase I activity. The invention further provides compositions comprising enzymes or microorganisms having induced and/or stabilized activity.
