  • Patent number: 8062633
    Abstract: The present invention relates to a formulation useful to control Listeria monocytogenes that comprises three new lactic acid bacteria, namely Carnobacterium maltaromaticum ATCC® PTA-9380, C. maltaromaticum ATCC® PTA-9381 and Enterococcus mundtii ATCC® PTA-9382 together with the bacteriocin nisin. This formulation is obtained from Inactivated Fermentates (IF) of these strains plus nisin and is designed to be used in the food industry. This formulation is used as an agent with tested antagonistic and bactericidal action against the pathogen Listeria monocytogenes, the microorganism that causes listeriosis, a food-borne disease, in humans. Based on this formulation, 2 surface sanitizing products can be obtained, a liquid and a solid. Both surface sanitizers can be applied to sanitize equipments, devices, working surfaces, gutters and drainages, especially in the food industry.

  • Publication number: 20090214503
    Abstract: The present application is directed to a new Bacillus subtilis strain deposited under the access number ATCC® PTA-8805, to bioproduct formulations comprising viable cells of the new strain, which can be encapsulated or in a concentrated liquid form, and to the use of these bioproducts to biologically control and decrease the incidence of Rhizoctonia solani, a plant pathogen that attacks economically important crops. The bioproducts are applied in encapsulated form directly over tubers or spraying a concentrated liquid form diluted in water over a plantation, and both formulations are applied in covered furrows.

  • Publication number: 20070116551
    Abstract: A device and method for holding a substrate, e.g., a semiconductor wafer, during a process, e.g., a liquid meniscus process, the substrate having a first side and a second side. The device includes one or more holding components, e.g., fingers, configured to contact a second side of the substrate without significantly contacting the first side of the substrate. At least one of the holding components may be configured to be moved during the process so as to prevent the at least one holding components from effecting the process, e.g., contacting the liquid meniscus. Such an arrangement may be employed when the substrate includes a top side having at least one structure or feature thereon, it being desirable that the holding components avoid contact with the structures or features during the process.

  • Patent number: 4496660
    Abstract: A catalyst for polymerizing olefins is the reaction product of (A) the reaction product of (1) the reaction product of (a) an alkyl magnesium compound such as dibutylmagnesium, with (b) an oxygen-containing and/or nitrogen-containing compound such as n-propyl alcohol, or isopropylamine, with (2) a halide source such as titanium tetrachloride or silicon tetrachloride; and (B) a transition metal compound such as titanium tetrachloride and (C) a reducing agent such as triisobutylaluminum.Also disclosed is a non-transition metal containing catalyst support for use in preparing olefin polymerization catalysts.The polymers which are produced in the presence of this catalyst and a cocatalyst such as triethylaluminum have a low catalyst support to transition metal ratio and therefore, the catalyst efficiency based on quantity of polymer per quantity of total catalyst is very high resulting in a polymer having good color and very little, if any, corrosion.
