MICROBACTERIC PROPERTIES OF A DISINFECTANT ON THE BASIS OF NADPROPIONIC ACID
The effectiveness of a new disinfectant was studied. The main active substance of which was stabilized nadpropionic acid, called Valisan-T on mycobacteria. The antimicrobial activity of Valisan T was studied on the test strains of Mycobacterium bovis 8 and Mycobacterium terrae 15755 ATCC, which were grown on Gelberg''s medium. The cultures were rinsed from the nutrient medium with sterile tap water, the bacterial mass concentration was adjusted according to the turbidity standard to 10<sup>9</sup> CFU/ml (20% horse blood serum was added as the protein protection). It is established that Valian-T can be applied for disinfection of rooms at tuberculosis at concentration of 1,5% by irrigation at a rate of 1,0 l/m<sup>2</sup>, at exposition 60 minutes, without heating the solution.
