Inhibition of bacterial pathogens by B. velezensis 9D-6 in in vitro plate assays. Representative plates are shown, along with average degree of inhibition zone of clearance measurements: (−) = no inhibition, (+) = 0.1–1.9 mm, (++) = 2.0–4.9 mm, (+++) = 5.0–9.9 mm, (++++) 10.0 mm+. B. cereus causes necrotic enteritis of mammals, including humans [52]; C. michiganensis causes bacterial canker of tomato [10]; E. amylovora causes fire blight of apple and pear [53]; P. agglomerans causes several diseases of several crops [54]; P. syringae DC3000 causes bacterial speck of tomato, Arabidopsis, and Nicotiana benthamiana [55]; R. solanacearum causes several diseases of several crops [56]; X. campestris causes black rot of the Brassicaceae family (including broccoli and radish) [57]; X. euvesicatoria causes bacterial spot of tomato [58]
