Changes in growth kinetics and motility characteristics of Escherichia coli in the presence of sulphoraphane isolated from broccoli seed meal

Summary In this investigation, the purified sulphoraphane from broccoli seed meal was evaluated in a range of 5–400 μg mL −1 against Escherichia coli . The results showed that levels above 200 μg mL −1 can inhibit 100% growth of 10 6 CFU mL −1 up to 5 h and cause a deformation of sigmoid behaviour in the growth kinetics, and even the bacterial population is reduced. On the other hand, low sulphoraphane levels such as 5–25 μg mL −1 also have...
