Patent number: 7491517Abstract: Methods for producing quadrivalent meningococcal meningitis polysaccharide and conjugate vaccines for serotypes A, C, Y and W-135 disclosed. Neisseria meningitidis fastidious medium was designed to maximize the yield of capsular polysaccharides and generate minimal cellular biomass and endotoxin in a short duration of fermentation. The crude polysaccharides are isolated, purified, and mechanically depolymerized by sonication. These purified polysaccharides were found in human clinical trials to be safe and immunogenic against meningococcal disease caused by N. meningitidis A, C, Y and W-135 serogroups in sub-Saharan Africa. In the preferred embodiment, the polysaccharides are conjugated to carrier proteins of diphtheria or tetanus toxiod to an average molecular size of 5100 to 9900 Daltons and provide broad spectrum protection to humans of all ages. Accelerated polysaccharide production and the efficacy of the resulting vaccine are demonstrated.Type: GrantFiled: February 28, 2007Date of Patent: February 17, 2009Inventor: Jeeri R Reddy

Publication number: 20090042276Abstract: Six hop acids are common to hops and beer: alpha acid, beta acids, isoalpha acids, rho-isoalpha acids, tetrahydro-isoalpha acids, and hexahydro-isoalpha acids. The six hop acids were tested to determine which were the most effective in inhibiting the growth of bacteria common to fuel ethanol production. The bacteria used in the tests were Lactobacillus brevis and Lactobacillus fermentum. The minimum inhibitory concentrations (MIC) of the hop acids were determined using MRS-broth. Molasses mash and wheat mashes were used as the growth media for the fermentations. In all cases the hop acids controlled the growth of these two lactobacillus bacteria with tetrahydroisoalpha acid, hexahydroisoalpha acid, and isoalpha acid killing the most bacteria at the lowest MIC. Treating yeast propagators, steep tanks, and fermenters with a minimum inhibitory concentration of hop acids will stop bacteria growth, increase ethanol yields and avoid the need for antibiotics.Type: ApplicationFiled: March 7, 2008Publication date: February 12, 2009Applicant: John I.

Patent number: 7022509Abstract: A method for removing a gas from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the compound to be removed into the gas vesicles, and placing the gas vesicles such that the gas compound is removed from the site. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium—such as darkness, exponential growth stage, flocculation, or dissolved gas flotation—then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.Type: GrantFiled: May 10, 2002Date of Patent: April 4, 2006Assignee: The University of AkronInventors: Lu-Kwang Ju, Anand Sundararajan, Sunil Kashyap
