  • Patent number: 8450111
    Abstract: A one-step process for the lysis of microalgae cell walls and separation of the cellular lipids for use in biofuel production by utilizing a hydrophilic ionic liquid, 1-butyl-3-methylimidazolium. The hydrophilic ionic liquid both lyses the microalgae cell walls and forms two immiscible layers, one of which consists of the lipid contents of the lysed cells. After mixture of the hydrophilic ionic liquid with a suspension of microalgae cells, gravity causes a hydrophobic lipid phase to move to a top phase where it is removed from the mixture and purified. The hydrophilic ionic liquid is recycled to lyse new microalgae suspensions.

  • Publication number: 20120178123
    Abstract: A method for stimulating enhanced lipid accumulation by algae includes growing algae in a bioreactor medium including nutrients. The algae have an average lipid content that averages a first % of total cell biomass. A stress inducing environmental condition is initiated that keeps the algae alive, stops cell reproduction, and induces the algae to accumulate additional lipids resulting in a second average lipid content that is at least 50% more than the first %. The method can include measuring a lipid concentration of the algae while under the stress inducing environmental condition, harvesting lipids from more than 50% but not all of the algae when the lipid concentration is above a predetermined lipid limit, adding fresh medium to the bioreactor medium having algae not involved in the harvesting therein, and repeating the method, wherein the algae not involved in harvesting serves as a source for new algae growth.

The experimental sample is grown with a stressing agent and regimen. The samples are admixed, and the formed composite is mass spectroscopically assayed for analyte peaks. The ratio of first isotope to second isotope is determined for the peaks, as is a sample median isotopic ratio. The ratio for assayed analyte peaks is compared with the median ratio. An analyte whose isotopic ratio significantly deviates from the median ratio is an analyte affected by the stressing agent.

Said microorganism is a thermophilic, acetogenic, hydrogen producing bacterium. As an example, Caldicellulosiruptor saccharolyticus is applied. According to the invention production if methane containing biogas is significantly increased. The invention is useful for intensifying biogas production and thereby increasing its feasibility.

  • Patent number: 7871792
    Abstract: An isolated microbial consortium is described that includes a first microbial consortium having Thermacetogenium phaeum to metabolize a complex hydrocarbon substrate into metabolic products comprising an acetate compound. The consortium also includes a second microbial consortium having a methanogen to convert the acetate compound into a final product that includes methane. Also, a method of increasing production of materials with enhanced hydrogen content. The method includes isolating Thermacetogenium phaeum from geologic formation water, culturing the isolated Thermacetogenium phaeum to increase the Thermacetogenium phaeum population, and introducing a consortium of the cultured Thermacetogenium phaeum, which may include spores of Thermacetogenium phaeum, into a hydrocarbon formation containing a complex hydrocarbon substrate.

  • Publication number: 20100330615
    Abstract: The present invention refers to a process to produce biodiesel and/or fuel oil from microbial oilseed and/or algal biomass and/or from sugar cane residues and derivatives. The products according to the present invention are appropriate for direct use in motors and to generate energy or steam. The integrated process of the present invention comprises the use, as raw materials, of microbial oil-producing biomass obtained from sugar cane residues and derivatives, which is integrated with algal biomass and/or glycerol and are processed by steps of production of oil-producing microbial biomass from filamentous fungi and/or yeasts, steps of simultaneous production of algal biomass by fully using residues, CO2 and residual broth of said production of microbial biomass, as well as steps of extraction and transesterification of lipids contained in the biomass, with reuse of the residual glycerol thus produced.

    Abstract: Methods for increasing methane emitted from organic waste and for collecting methane and other gaseous bi-products. A gas collection unit collects gas in a first separation tank, wherein the gas is separated into methane and other components. The methane is collected, and other components are diverted. A second separation tank receives diverted components combined with an acidic solution and further separates the components into carbon dioxide and other compounds. The carbon dioxide is collected for reuse in a variety of applications.

  • Patent number: 7820442
    Abstract: The present invention identifies that the expression of Activation Induced Deaminase (AID) or its homologues in cells confers a mutator phenotype and thus provides a method for generating diversity in a gene or gene product as well as cell lines capable of generating diversity in defined gene products. The invention also provides methods of modulating a mutator phenotype by modulating AID expression or activity.

  • Patent number: 7820963
    Abstract: A method for identifying a biological analyte that is affected by a stressor is disclosed in which two substantially identical biological samples are provided, with a first sample being a control sample and a second sample being an experimental sample. The control sample is grown with a nutrient having an isotope of a first atom, whereas the experimental sample is grown with a nutrient having a second isotope of the first atom. The experimental sample is grown with a stressing agent and regimen. The samples are admixed, and the formed composite is mass spectroscopically assayed for analyte peaks. The ratio of first isotope to second isotope is determined for the peaks, as is a sample median isotopic ratio. The ratio for assayed analyte peaks is compared with the median ratio. An analyte whose isotopic ratio significantly deviates from the median ratio is an analyte affected by the stressing agent.

  • Patent number: 7803566
    Abstract: The present invention relates to the identification of gene sequences and proteins involved in vaccinia virus dominant T cell epitopes. Two vaccinia virus CD8+ T cell epitopes restricted by the most common human MHC class I allele, HLA-A0201 have been identified. Both epitopes are highly conserved in vaccinia and variola viruses. The induction of the T cell responses following primary vaccination is demonstrated by the kinetics of epitope specific CD8+ T cells in 3 HLA-A0201 individuals. This information will be useful for the design and analyses of the immunogenicity of experimental vaccinia vaccines, and for basic studies of human T cell memory.

  • Patent number: 7758854
    Abstract: Antimicrobial agents that can serve as replacements to conventional pharmaceutical antibiotics are disclosed. The antimicrobial agents comprise conjugatively transmissible plasmids that kill targeted pathogenic bacteria, but are not harmful to donor bacteria. Two types of lethal transmissible plasmids are disclosed. One type kills recipient bacteria by unchecked (“runaway”) replication in the recipient cells and is prevented from occuring in donor cells. Another type kills recipient bacteria by expressing a gene that produces a product detrimental or lethal to recipient bacterial cells, that gene being prevented from expression in donor cells.
