[Retracted] Analysis of Research Status and Development Trend of Nanotoxicology of Liliaceae Medicinal Plants

Table 1

Dose response of single bacteria to silver nanoparticles.

Strain	Dose (mg/L)	Lower cell density
Staphylococcus aureus	0.03	Lower cell density
Escherichia coli		At higher dose
Nitrosomonas europaea	0.002−2	Growth over 100% at certain doses, depending on pH and presence of humic acids
Pseudomonas stutzeri	0.0025−5	Ammonia monooxygenase gene sup regulated when 0.0025 mg/L was used
Azotobacter vinelandii	4	Strain dependent minimum inhibitory concentration (MIC)
Arthrobacter globiformis	12	Inhibition ratio increase with dose; inhibition-dose curve flattens at higher dose
Azotobacter vinelandii	0.1−100	Slower growth rate at higher concentration
