Microbial background and concentration of hydrogen ions in native zeolite

Based on the results of bacteriological studies, it was found that native zeolite does not contain mycotoxin-producing fungi. CFU cultures of bacteria on plant roots ranged from a minimum value of 3.88M07 in the first sample to 4.97M07 in the second sample, a total of 24 bacterial isolates were isolated. In order to confirm the research, a qualitative PCR method was used to determine the presence of fungi and bacteria in native zeolite and on plant roots, which also gave a negative result. Hydrogen ion concentration. The concentration of hydrogen ions in native zeolite, depending on the time, was greater than 9 after 30 seconds, 10 minutes and 15 minutes at a ratio of zeolite to distilled water of 1:6 and 1:8. At a ratio of 1:1, the maximum concentration of hydrogen ions was 8.51.
