The effects of four alkylhydroxybenzene (AHB) homologs of different hydrocarbon chain lengths on synthesis of the pigment violacein induced by C6-homoserine lactone (HSL) and biofilm formation by Chromobacterium violaceum NCTC 13274 and on Escherichia coli pAL103 bioluminescence in the presence of C6-oxo-HSL were studied. It was shown that the inhibitory effect of alkylhydroxybenzenes on the growth of C. violaceum increased in the C5-AHB --> C12-AHB series in the absence of this activity in C1-AHB.

- The study used atomic force microscopy to examine how low doses of ampicillin affect the size and structure of Escherichia coli and Bacillus cereus bacteria.
- The results showed that both types of bacteria increased in size due to inner osmotic pressure affecting their weakened cell walls.
- E. coli displayed unusual elongated shapes and structural anomalies, while B. cereus primarily changed from a rod to a spherical shape, releasing peptidoglycan fragments as a result of the antibiotic.
