Figure 1

The growth of selected isolates on BH medium supplemented with 2% gasoline, diesel, benzene, hexane, and olive oil. OD (600nm) is given in the y-axis, and the number of days is given in the x-axis. Bacillus species isolates are SB1, SB2, SB3, SB4, SB5, SB6, SB7, SB8, SO5, SO9, SO10, SO14, SO17, SO18, M14, M21, M22, M23, M24, M25, M26, M27, M28, M29, M30, M31, ST45, ST49, ST54, and ST70.
