Figure 3

Influence of the vapors of ethanol (EtV), 1-octanol (OcV) and aqueous tea extract (TeaV) on Pseudomonas sp. NEEL19, cultured in DSMZ 125* without and with 0.1% (w/v) Trp (BM and BMW, respectively). (a) optical cell density (OD600), (b) cultivable cell count, (c) cell viability, (d) media alkalization and (e) IAA production are shown; microplate sections obtained in this study (c‒e) represent corresponding chromogenic reactions. Inoculated Trp-fee DSMZ 125* without vapor treatment was used as a control. Error bar, mean (n = 4) ± s.d. *P < 0.1, **P < 0.05, ***P < 0.01, ****P < 0.0001; ns, non-significant. Treatment codes are defined in the section abbreviations.
