  • Patent number: 6159726
    Abstract: A method of biotreating a solid material to remove an undesired compound using a nonstirred surface bioreactor is provided. According to the method the surface of a plurality of coarse substrates is coated with a solid material to be biotreated to form a plurality of coated coarse substrates. The coarse substrates have a particle size greater than about 0.3 cm and the solid material to be biotreated has a particle size less than about 250 .mu.m. A nonstirred surface reactor is then formed by stacking the plurality of coated coarse substrates into a heap or placing the plurality of coated coarse substrates into a tank so that the void volume of the reactor is greater than or equal to about 25%. The reactor is inoculated with a microorganism capable of degrading the undesired compound in the solid material, and the solid material is then biotreated in the surface bioreactor until the undesired compound in the solid material is degraded to a desired concentration.

  • Patent number: 6150157
    Abstract: The invention provides methods and microbial cultures for the bioremediation of organic halide contaminated groundwater contaminated with organic halides, such as di- and trichloroethene. The methods involve adding, in situ to organic halide-contaminated groundwater a carbohydrate and one or more reductive dehalogenation factors, usually in the form of a nutrient extract, both in amounts sufficient to permit in situ reductive dehalogenation of the organic halide by a microbial population. The microbial population may be endogenous to the ground water or added exogenously. The nutrient-enriched ground water is then maintained in situ under reducing conditions to reductively dehalogenate the contaminating organic halide. Enriched bioremediation cultures are produced by adding to organic halide contaminated groundwater which comprises an endogenous microbial population capable of reductive dehalogenation of the organic halide a carbohydrate and frequently, one or more reductive dehalogenation factors.

  • Patent number: 6136193
    Abstract: This invention provides a process for the biotreatment of wastewater from pulping industries. Sulfides are removed by a number of strains of bacteria from the genus Thiobacillus or Thiobacillus denitrificans. COD and BOD are concurrently removed with the sulfides by an improved co-cultural blend comprising co-cultures of a number of strains of the Thiobacillus or Thiobacillus denitrificans bacteria with heterotrophs. At least approximately 20%, and preferably between approximately 40% and approximately 60%, of the improved co-cultural blend comprises the co-cultures of a number of strains of the Thiobacillus or Thiobacillus denitrificans bacteria with the heterotrophs. Acclimation of the heterotrophs to the species to be removed is accomplished with biological acclimation reactors which reduce mycell toxicity for the heterotrophs. To control pH of the heterotrophic reaction with inorganic and organic sulfides, magnesium oxide (MgO) is utilized along with caustic.

  • Patent number: 6051420
    Abstract: An efficient method for decontaminating soil containing organic explosives ("TNT" and others) in the form of solid portions or chunks which are not ordinarily subject to effective bacterial degradation. The contaminated soil is treated by delivering an organic solvent to the soil which is capable of dissolving the explosives. This process makes the explosives more bioavailable to natural bacteria in the soil which can decompose the explosives. An organic nutrient composition is also preferably added to facilitate decomposition and yield a compost product. After dissolution, the explosives are allowed to remain in the soil until they are decomposed by the bacteria. Decomposition occurs directly in the soil which avoids the need to remove both the explosives and the solvents (which either evaporate or are decomposed by the bacteria). Decomposition is directly facilitated by the solvent pre-treatment process described above which enables rapid bacterial remediation of the soil.

If rinsing of the lens is not carried out after cleaning and disinfecting, this procedure prevents eye damage by inhibiting remaining enzyme activity and using a mild disinfectant. Preferred enzymes are proteases such as an acidic aspartic protease, a cysteine protease, a serine protease or a metalloprotease, and preferred enzyme inhibitors function both as an inhibitor and as a mild disinfectant such as chloramine-T, chloramine-B, bacitracin or aryl boronic acids. In a preferred method, the enzyme is subtilisin A and the enzyme inhibitor and disinfectant is chloramine-T.

  • Patent number: 5981266
    Abstract: An anaerobic process of desulfurizing a sour natural gas stream wherein a selected consortium of chemoautotrophic bacteria converts H.sub.2 S and other sulfur species into elemental sulfur, which is recovered as a product. The process is conducted at pressures of up to 1000 psi and temperatures up to 140.degree. F. (10.degree. C. to 60.degree. C.), and mitigates up to 10,000 ppm H.sub.2 S to pipeline standards of .ltoreq.4 ppm and up to 10% CO.sub.2 to .ltoreq.2% CO.sub.2.

  • Patent number: 5976210
    Abstract: A granular fertilizer which provides plant assimilatable nutrients by both hydrolysis and bacterial activity, and which includes biological growth promoting nutrients. The fertilizer is made by blending and pelletizing an aggregate of conventional fertilizing materials, biological food source materials and at least one hydrophilic material which expands upon wetting and becomes porous and wick-like upon heating to drive off absorbed water. In its dry state, the hydrophilic material wicks up applied liquid biological inoculum which remains dormant until dispensed and exposed to adequate heat and moisture.

  • Patent number: 5972686
    Abstract: The present invention relates to a novel ice nucleation active Xanthomonas strain and a bacterial ice nucleator comprising the ice nucleation active microorganism which can be applied for food processing and artificial snow making. The present inventors have screened ice nucleation active microorganisms from leaves of crops and plants, and investigated their ice-nucleation activities. As a result, the inventors discovered that a novel microorganism belonging to Xanthomonas campestris has a superior ice-nucleation activity than those of the conventional ice nucleation active microorganisms. Accordingly, the ice nucleation active microorganism of the invention can be used as a potent bacterial ice nucleator for food processing and artificial snow making.
