  • Method for in-situ immobilization of lead in contaminated soils, wastes, and sediments using solid calcium phosphate materials
    Patent number: 5512702
    Abstract: Solid calcium phosphate materials are used for in-situ immobilization of lead contaminated soils, wastes, and sediments by mixing the solid calcium phosphate material with the lead contaminated material and leaving the mixture in place. The solid calcium phosphate material includes, for example, naturally occurring apatite, synthetic hydroxyapatite, dibasic calcium phosphate, or phosphate rock.

  • S-triazine degrading bacteria
    Patent number: 5429949
    Abstract: A pure bacterial culture, designated herein as M91-3, has been isolated which rapidly degrades certain s-triazines, particularly halogenated s-triazines. The M91-3 degrades s-triazines, particularly atrazine, beyond the point of ring cleavage, leading to complete mineralization of the atrazine. The ability of M91-3 to completely degrade atrazine appears to be unique among bacteria. The M91-3 is capable of degrading s-triazine in solution and in presence of soil or sediment. The invention also relates to a method for degrading s-triazines, particularly atrazine.
