Growth of Paenibacillus sp. strain TSY30 and Rhizobium sp. strain TSY03b by degrading aromatic compounds as the substrate. (a) Degradation of naphthalene and production of salicylic acid (SA) by strain TSY30; (b) degradation of DF and production of SA by strain TSY30; (c) degradation of DD in the presence of DF by strain TSY30; (d) degradation of naphthalene and production of SA by strain TSY03b; (e) degradation of DF in the presence of naphthalene by strain TSY03b; (f) degradation of biphenyl in the presence of naphthalene by strain TSY03b. Symbols: closed circles, growth (OD₆₆₀); open circles, concentration of naphthalene; open squares, DF; closed squares, DD; open triangles, biphenyl; closed triangles, SA.
