Densities in heterotrophic and specialized bacteria and ergosterol contents in myco-augmented microcosms and respective controls. Changes in concentration of indigenous cultivable aerobic bacteria and in ergosterol content after 0, 30 and 60 d treatment at 28°C in the incubation control and Lentinus tigrinus microcosms in the absence (i.e., ICM and Lt M respectively) and in the presence (i.e., ICSOM and Lt SOM) of soybean oil (2.5%, w/w). A, Total aerobic heterotrophic bacteria; B, specialized aerobic bacteria able to growth on biphenyl; C, specialized aerobic bacteria able to growth on monochlorobenzoic acids (CBA); D, ergosterol. Data are means ± standard deviations of 2 replicated experiments. Multiple pair-wise comparisons were performed by the Tukey test (P < 0.05). Same lower case and upper case letters denote absence of statistical significance between time-dependent changes within the same treatment and between treatments at the same time, respectively.
