Dose–Response Effect of Nitrogen on Microbial Community during Hydrocarbon Biodegradation in Simplified Model System

Knowledge about the influence of C:N ratio on biodegradation process hydrocarbon compounds is significant importance in development biostimulation techniques. The purpose this study was to assess impact nitrogen environmental consortium during biological decomposition hydrocarbons. experimental variants represented low, moderate, and excessive with compounds. metabolic activity tested using flow cytometry technique. efficiency hydrocarbons consortium, based gas chromatography method, metapopulation changes, analysis V4 16srRNA sequencing data, were assessed. results research confirm positive effect properly optimized polycyclic aromatic negative microorganisms also proven. Low resistance changes supply demonstrated among orders Xanthomonadales, Burkholderiales, Sphingomonadales, Flavobacteriales, Sphingobacteriales. It proven that quantitative order Rhizobiales, characterized by a high-predicted potential for hydrocarbons, may be helpful optimization processes areas high deficiency.
