摘要: article i nfo Pharmacological studies focus on susceptibility of pathogenic microbes against specific drugs or combinations them, ecological substrate utilization efficiency variable microbial communities. The Micro- Resp™ system was especially developed to study soil It slightly modified facil- itate exploring growth in a concentration-dependent fashion (microdilutions carbohydrate mixtures toxic chemicals). After turbidimetric assessment, colorimetric indi- cator plates (cresol red agar) were mounted the assay plates. utilisation design is illustrated by glucose and plant mixture, antimicrobial naphthoquinone juglone. Dose-response effects are explored curve fitting nonlinear models that have been detect hormetic characterized stimulation at lower followed inhibition higher dosages (U- inverse U-shaped effects). Multivariate analyses presented utilizing metavariables obtained process measured parameters respiration factor efficiency.
