Methods for purifying water or water-containing material using microorganisms and living bacterial preparations as well as method for preparing and storing same
A method for purifying water or a water-containing material which comprises using a single or a few bacterial strains whose growth(s) is or are enabled or promoted by the addition of one or more of S-, N- and C- compounds under a low nutritional condition. A living bacterial preparation, useful for the purification of water or water-containing material, comprising a single or a few bacterial strains whose growth(s) is or are enabled or promoted by addition of one or more of S-, N- and C- compounds under a low nutritional condition is also disclosed.
The strains of Acinetobacter species (bicoccus) B-6445, Arthrobacter species S-1212, and Rhodococcus species S-1213 were deposited on Jan. 1, 1993 in the All-Union collection at the All-Union research institute for genetics and selection of microorganisms. A method for biological purification from oil pollutions and spills incorporates introduction of a bacterial culture into the pollution or spill, used as the bacterial culture being made of the strains mentioned before, taken either individually or in any combination with one another, the weight ratio between the bacterial culture and the oil pollution being 1:10-10.sup.5, respectively.

The present invention provides compositions and methods for controlling fecal odor production that develops from agricultural waste which accumulates because of the scale of hog and chicken farming. The compositions for controlling odor in waste comprise isolates of Pseudomonas sp. that assimilate ammonia, degrade skatole and reduce COD. The present invention further provides methods for controlling odors in animal waste storage facilities using the abovementioned Pseudomonas sp. compositions.
Mixed bacterial compositions minimally contain a mixed population of bacteria including at least one species of Nitrosomonas capable of converting ammonia to nitrite, at least one species of Nitrobacter capable of converting nitrite to nitrate, at least one species of Pseudomonas capable of converting nitrate to nitrite and capable of metabolizing urea, and at least one species of Enterobacter capable of metabolizing bacterial waste products and fermenting lactose. The ability of these aforementioned bacteria to metabolize the odor; and partially decompose the waste material producing the odor is enhanced by the addition of an acclimated mixed bacterial culture to the mixed bacterial composition containing the aforementioned species of Nitrosomonas, Nitrobacter, Pseudomonas, and Enterobacter. The acclimated mixed bacterial culture includes at least one and up to four different species or strains of Pseudomonas, at least one species of Acinetobacter, and at least one species of Enterobacter. The mixed bacterial compositions of the present invention can optionally contain at least one species of Bacillus. These mixed bacterial compositions can be applied to human and animal organic waste to reduce the odor and partially degrade the waste.
