Titanium complexes affectBacillus subtilisbiofilm formation

Abstract

Biofilms are surface or interface-associated communities of bacterial cells, embedded in a self-secreted extracellular matrix (ECM). Cells in biofilms are 100-1000 times more resistant to antibiotic treatment relative to planktonic...

Inclusion complex of quercetin with sulfobutylether β-cyclodextrin: preparation, characterization, antioxidant and antibacterial activities and the inclusion mechanism

“…Then, 50 μL of diluted bacterial solution (10 −6 ) was added to the inclusion complex solution and incubated at 37 °C, and the absorbance value measured at 600 nm at 0, 2, 4, 6, 8, 10, 12, 24, 30, 36 and 48 h, respectively. Meanwhile, at 12 h, the appropriate amounts of bacterial solution were taken out and diluted 10 7 times, and then 50 μL of diluted bacterial solution was added to a mannitol salt agar plate, and the plates were cultured at 37 °C for 48 h. 27 All samples were characterized in triplicate.…”

Design, synthesis and antimycobacterial activity of imidazo[1,5-a]quinolines and their zinc-complexes

“…As part of the innate immune response towards pathogens, macrophages can deploy phagosomal zinc intoxication defence mechanisms. 9 Antibacterial, 10–12 antifungal 13 and antiparasitic 14,15 features of metal-drug complexes have been observed in many studies.…”
