    Abstract: Described are novel S. stipitis strains that were obtained by UV-C irradiation of wild-type S. stipitis NRRL Y-7124 cultures, followed by 5-month anaerobic growth on xylose at 28° C. The UV-C-mutagenized strains were able to grow anaerobically on xylose or glucose medium with higher ethanol production than a Saccharomyces cerevisiae yeast strain under comparable fermentation conditions. The mutagenized strains were identified by DNA fingerprinting to be unique strains closely related to wild-type Scheffersomyces stipitis. These mutagenized strains have potential application in large-scale industrial conversion of lignocellulosic sugars to fuel ethanol.

The monocytes are induced to differentiate into dendritic cells by activation forces resulting from flow of the monocytes through a plastic channel, such as the plastic channel in a conventional photopheresis apparatus. Functional dendritic cells generated from induced monocytes are incubated together with apoptotic or inactivated disease effector agents to enhance the presentation of at least one disease-causing antigen expressed by the disease effector agents. Compositions including dendritic cells derived from induced monocytes and compositions including such dendritic cells incubated with disease effector agents are also provided for use in immunotherapeutic treatment.

  • Patent number: 6413765
    Abstract: Genetically modified lactic acid bacteria having a reduced or lacking or enhanced diacetyl reductase activity, acetoin reductase activity and/or butanediol dehydrogenase activity are provided. Such bacteria are used in starter cultures in the production of food products including dairy products where it is desired to have a high content of diacetyl and for reducing or completely removing diacetyl in beverages including beers, fruit juices and certain types of wine, where the presence of diacetyl is undesired.

  • Publication number: 20010028879
    Abstract: The development of graft versus host disease in a mammalian patient undergoing cell transplantation therapy for treatment of a bone marrow mediated disease, is prevented or alleviated by subjecting at least the T-cells of the allogeneic cell transplantation composition, extracorporeally, to oxidative stress, in appropriate dosage amounts, such as bubbling a gaseous mixture of ozone and oxygen through a suspension of the T-cells. The process may also include irradiation of the cells with UV light, simultaneously with the application of the oxidative stress. The oxidative stress induces reduced inflammatory cytokine production and a reduced proliferative response in the T-cells.

  • Patent number: 6204006
    Abstract: Microbial strains capable of producing enhanced levels of sphingosine, dihydrosphingosine, phytosphingosine and/or derivatives thereof are disclosed. Additionally, there are disclosed methods based on mutagenesis, or other selection techniques, whereby such strains can be produced. As a preferred example thereof, mutant strains of Pichia are provided that are capable of producing about 50% or more of such compounds than wild type strains.

  • Patent number: 6204058
    Abstract: An autoimmune vaccine is provided for administration to human patients to alleviate the symptoms of autoimmune diseases such as rheumatoid arthritis. The vaccine comprises an aliquot of the patient's blood, containing, inter alia, leukocytes having upregulated expression of various cell surface markers and lymphocytes containing decreased amounts of certain stress proteins. It is produced by subjecting the blood aliquot extracorporeally to certain stressors, namely oxidizing agents, UV radiation and elevated temperature.

  • Patent number: 6132989
    Abstract: The invention provides compositions of a non-adenoviral vector containing a polynucleotide sequence encoding adenoviral pTP operationally linked domain. The invention also provides compositions of an adenoviral pTP binding domain. The invention also provides methods for increasing the expression of a polynucleotide by expressing the polynucleotide in a non-adenoviral vector containing an adenoviral pTP binding domain in the presence of adenoviral pTP. The invention additionally provides methods to increase expression of a heterologous polynucleotide in an individual by obtaining cells from the individual, genetically altering the cells to express a non-adenoviral vector containing an adenoviral pTP binding domain and a gene encoding pTP and readministering the genetically altered cells to the individual.

  • Patent number: 5928866
    Abstract: This invention provides A method for preparing mutant genes, which comprises the steps of constructing a recombinant plasmid DNA by inserting a gene fragment into a plasmid DNA having a unidirectional origin, introducing the recombinant plasmid DNA into host cell lacking DNA error-correcting function to transform the host cell, and culturing the transformant cell in a condition that any mutations of the inserted gene is detectable. According to the present invention, diverse mutant genes can be prepared in a short period of time.
