摘要:
A method of detecting peptide fragments of protein(s) that are differentially present in biological samples. The identity of the peptides may be determined and correlated with the protein(s) that are differentially present in the samples.

A modified cultured yeast product for human and animal consumption is produced by combining yeast cream and yeast centrate to produce a cream/centrate mixture, autolyzing the mixture, inactivating by heating the mixture and optionally drying. After autolysis, hydrolysis may be carried out by the use of acids, alkalis or enzymes. The yeast cream and yeast centrate are preferably produced by culturing Kluveromyces marxianus or Candida intermedia in a whey permeate and separating yeast cream and yeast centrate from the cultured whey permeate. The cream and centrate are combined such that the ratio of total solids of cream to total solids of centrate is between about 0.3 and 1.6 and preferably about 1:1.

Cell lines have been produced that secrete monoclonal antibodies capable of binding to the flagellar proteins of selected Pseudomonas aeruginosa strains. Some of these antibodies have been found to be protective against lethal challenges of P. aeruginosa. Pharmaceutical compositions containing these antibodies, which can be in combination with other monoclonal antibodies, blood plasma fractions and antimicrobial agents, and the prophylactic and therapeutic use of such compositions in the management of infections, are included.Prior to filing this application, the continuous transformed cell lines PaF4 IVE8, FA6 IIG5, 20H11, and 21B8, described herein, were deposited in the America Type Culture Collection and given the designations HB9129, HB9130, CRL 9300, and CRL 9301, respectively.

Novel yeasts are disclosed including Pichia pastoris NRRL Y-11430, yeasts having the characteristics of Pichia pastoris NRRL Y-11430, mutants of Pichia pastoris NRRL Y-11430, and strains derived therefrom. Also disclosed are methods of culturing the strains, and biochemical conversions employing the strains.
摘要:
Disclosed is a new material having antiviral activity designated interferon epsilon. The material may be produced, for example, by exposing primary, diploid human epithelial cells to a virus and then incubating the cells under conditions in which the new interferon is produced and is secreted into the culture medium. The material is antigenically distinct from interferon alpha, interferon beta, and interferon gamma, and displays marked antiviral activity in human epithelial cells but no detectable activity in other cell types.
摘要:
The process consists of cultivating, at a temperature below 28.degree. C., the fungus Trichoderma album in liquid nutrient media, the pH of said media being kept at a value comprised between about 3.7 and 4.8, the dissolved oxygen content being from about 6 to 10 mg/l. The cultivation is carried out with non-traumatizing, efficient stirring and under conditions such that multiplication is practically nil and then recovering said new strain Trichoderma album.
摘要:
Process for the culture of aerobic microorganisms in a culture medium provided with at least one source of oxygen, at least one source of carbon and at least one source of hydrogen, comprises providing oxygen originating from the decomposition of hydrogen peroxide as a source of oxygen and providing at least one highly inflammable product as a source of carbon and hydrogen.
摘要:
A broth containing yeast cells is continuously or intermittently removed from a fermentor. Then, yeast cells are separated from the filtrate using a cell separator, or further washed with water. Then, the yeast cells so obtained are recycled to the fermentor, whereby yeasts are cultivated at a high cell concentration of from 6% to about 20% based on dry weight. As discussed herein, by removing the filtrate from the cultivation system, there is no accumulation of metabolites and salts prohibiting the cultivation of yeasts, and further the growth of miscellaneous microorganisms which interfere with yeast cell growth, is surprisingly suppressed.
