Keywords: Kalanxoye degremona dorivor o‘simligining ildizidan 2ta, poyasidan 3ta va bargidan 3ta jami 8ta endofit izolyatlar ajratib olindi. Skrining natijasida Kalanxoye degremonadan ajratib olingan K7 izolyati tanlab olindi va MALDI TOF mass-spektrometriya usuli yordamida identifikatsiya qilindi. Tanlab olingan K7 bakteriya izolyati B.amyloliquefaciens ekanligi aniqlandi va B.amyloliquefaciens – UzMU 22 shtammi deb nomlandi. Bacillus amyloliquefaciens - UzMU 22 shtammining Verticillium dahliae, Alternaria alternata, Fusarium solani ва Fusarium oxysporum kabi patogen zamburug‘larga nisbatan antogonistik faolligi, kanamitsin, eritromitsin, sefotoksin, seprofloksatsin, gentamitsin va lenkomitsin kabi bir nechta antibiotiklarga sezgirligi va gidrolitik fermentlar faolligi aniqlandi.

Abstract

A total of 8 endophytic isolates were isolated from the root of the medicinal plant Kalanchoe degremona, 3 from the stem and 3 from the leaves. As a result of the screening, isolate K7, isolated from Kalanchoe degremona, was isolated and identified by MALDI TOF mass spectrometry. The isolated bacterial isolate K7 was identified as B. amyloliquefaciens and named B. amyloliquefaciens - strain UzMU 22. The antigonistic activity of the Bacillus amyloliquefaciens strain - UzMU 22 was determined against such pathogenic fungi as Verticillium dahliae, Alternaria alternata, Fusarium solani and Fusarium oxysporum, sensitivity to a number of antibiotics, such as kanamycin, erythromycin, cefotoxin, ceprofloxacin, gentamicin and lencomycin, as well as the activity of hydrolytic enzymes.
