Streptomyces Venezuelae Patents (Class 435/906)
  • Patent number: 11638406
    Abstract: A bioreactor includes a first compartment designed to retain seaweed sporophytes, a second compartment in fluid communication with the first compartment that includes one or more settlement surfaces, and a first porous barrier between the first and second compartments that allows the seaweed spores to pass from the first compartment to the second compartment, and systems comprising the bioreactor. Also provided herein are methods of culturing seaweed, for example, using a bioreactor provided herein.

  • Patent number: 8092685
    Abstract: Methods and systems for growing algae are disclosed. For example, disclosed is an exemplary bioreactor for growing algae that includes a chamber, a liquid-permeable membrane that includes a plurality of hollow fiber membranes disposed within the chamber. Each hollow fiber membrane can include a hollow interior and may be made of a liquid-permeable, algae-impermeable membrane, and each hollow fiber membrane may be disposed within the chamber. The respective interiors of the hollow fiber membranes may at least partially define an inner-capillary space (ICS). The interior of the chamber and respective exteriors of the hollow fiber membranes may at least partially define an extra-capillary space (ECS). When algae is grown in the ECS, lipids produced by the algae may be extracted from the ECS to the ICS via the hollow fiber membranes without killing the majority of algae and while containing the algae to the ECS.

  • Patent number: 6258525
    Abstract: Methods for labeling mannose lectins on the surface of mammalian sperm cells are described, and methods of categorizing and quantifying the numbers of cells exhibiting particular labeling patterns are also provided. These methods provide ways of detecting whether or not a mammalian male patient has mannose lectin-correlated infertility, which is determined on the basis of the relative numbers of sperm cells labeled with particular labeling patterns. Methods for detecting capacitation-induced changes in the distribution of mannose lectins on mammalian sperm cells are also provided, and these methods can also be used to detect whether or not a mammalian male patient has mannose lectin-correlated infertility, on the basis of the comparative relative labeling in capacitated and non-capacitated sperm cell samples. In addition, the various methods are shown to be useful for determining whether chemical compounds have effects on mammalian sperm cell surface lectin distribution or acrosomal states.

  • Patent number: 5232846
    Abstract: The present invention is directed toward a thermostable lipoprotein lipase capable of hydrolyzing triglycerides in lipoproteins to glycerol and fatty acids, a process for producing the thermostable lipoprotein lipase, and a blood triglyceride determining reagent containing the thermostable lipoprotein lipase. The thermostable lipoprotein lipase exhibits about 100% retention of the hydrolyzing activity when treated in a buffer having a pH of from bout 4 to 7 at about 60.degree. C. for about 15 minutes and a glycerol forming activity/fatty acid forming activity ratio of at least about 15%. The process comprises cultivating a thermophilic actinomycetes, particularly Streptomyces 7825 (FERM P-9983, FERM BP-2489 is cultivated to produce a thermostable lipoprotein lipase.

  • Patent number: 4703009
    Abstract: Novel plasmid pVE1, deletion mutants thereof, recombinant derivatives thereof, which is the same as the genome or nucleic acid of such plasmids and derivatives of such genome, which are useful as recombinant DNA cloning vectors into host organisms, such as bacteria, for example, Streptomyces avermitilis; portions of such plasmid genome are additionally useful as adjuncts in recombinant DNA cloning procedures, for examples: 1. to permit the maintenance of cloned DNA in the host, either in an integrated state or as an autonomous element; 2. to serve as promoters for increasing expression of endogenous or foreign genes wherein said promoters are ligated to such genes or otherwise serve as promoters; and 3.
