摘要:
Methods and compositions for producing fatty acid derivatives, for example, fatty esters, and commercial fuel compositions comprising fatty acid derivatives are described.
摘要:
The present invention relates to an attenuated strain of Salmonella comprising a DNA molecule encoding CMV pp65. In particular, the present invention relates to the use of said attenuated strain of Salmonella in cancer immunotherapy.
摘要:
The invention relates to a method for selecting a yeast strain having improved capability for fermenting a pentose, advantageously xylose, in the presence of organic acid, advantageously acetic acid, in non-dissociated form, in which at least one yeast strain that is capable of fermenting said pentose is consecutively cultured in the following two media: a first growth medium comprising said pentose as the only carbon source and said organic acid in non-dissociated form; a second growth medium comprising another carbon source as the only carbon source, advantageously glucose, free of said organic acid in non-dissociated form, the consecutive culture in at least said two growth media being repeated at least twice, in the presence of rising concentrations of organic acid in non-dissociated form.
摘要:
Described are compositions and methods relating to variant filamentous fungi having altered growth characteristics. Such variants are well-suited for growth in submerged cultures, e.g., for the large-scale production of enzymes and other proteins for commercial applications.
摘要:
The application relates to a Yersinia pseudotuberculosis cell, which comprises nucleic acid coding for expression of at least one Yersinia pestis Caf1 polypeptide or of at least one antigenic fragment of Yersinia pestis Caf1, more particularly to an attenuated Y. pseudotuberculosis cell, which expresses the Y. pestis capsule. Said Y. pseudotuberculosis cell is exceptionally efficient in protecting against both bubonic plague and pulmonary plague.
摘要:
The present invention is drawn to a live, attenuated S. Paratyphi A strain, a live, attenuated S. Paratyphi A strain comprising a stabilized plasmid expression system, an S. Paratyphi conjugate vaccine, and methods of using these strains and conjugate vaccine.
