The present work describes a research approach to the aerobic bioleaching of U IV ores. Three strains Acidithiobacillus sp. isolated from sulfur springs in Ramsar province, Iran and nucleotide sequences of gene fragments of examined Acidithiobacillus sp. strains were recorded in NCBI .Then, uranium bioleaching experiment carried out with native bacteria in different pulp densities.

US4326052A - Deacetylated polysaccharide S-60 - Google Patents

Deacetylated Polysaccharide S-60, prepared by deacetylating the polysaccharide S-60 produced by fermentation of Pseudomonas elodea, ATCC 31461, has valuable properties in both the clarified and non-clarified form, and is useful as an agar substitute or a shapeable room deodorant. The non-clarified deacetylated gum contains about 17% protein and principally carbohydrate, which comprises ...

Free-living amoebae FLA are ubiquitous organisms that have been isolated from various domestic water systems, such as cooling towers and hospital water networks. In addition to their own pathogenicity, FLA can also act as Trojan horses and be naturally infected with amoeba-resisting bacteria ARB that may be involved in human infections, such as pneumonia.
