Özet
In numerous countries, the utilization of plants for both nutritional and therapeutic purposes is a common practice. However, the inadvertent use of these plants can pose risks due to their active molecules or microbiota. The traditional use of Herniaria glabra L. (H. glabra) plant in treating various diseases is well-known; however, its application in yogurt production raises concerns. In this study, Bacillus pumilus isolated from H. glabra was identified through 16s rRNA sequencing and MALDI-TOF MS (Matriks Assisted Lazer Desorption Ionization Time of Flight Massspectrometry). The bacterium's resistance under simulated gastrointestinal tract (GIT) conditions was assessed, followed by investigations into its aggregation ability, antibiotic resistance, hemolytic activity, and antagonistic potential through in vitro tests. The study revealed that B. pumilus exhibited 100% resistance to GIT conditions. Notably, the bacterium demonstrated strong autoaggregation (34.48%) and coaggregation abilities (49.82% for Escherichia coli, 49.13% for Listeria monocytogenes), signifying a potent aggregative potential. Sensitivity to most tested antibiotics was observed, while no antagonistic activity against tested bacteria was evident. Furthermore, the bacterium exhibited beta-hemolytic activity, indicative of potential virulence. The findings suggest that this resistant yet virulent bacterium, with its hemolytic activity, could disrupt the GIT balance, posing serious health risks. The study underscores the need for caution and awareness regarding the potential dangers posed by bacteria in plant microbiota in herbal therapies.
