Effect of the Type of Vitis vinifera Cultivation in the Cenophenoresistome and Metabolic Profiling (CLPP) of Edaphic Bacterial Communities

Abstract

: In the present work, bacterial soil communities of different grapevine exploitation samples are studied in order to elucidate the possible influence of different agrarian management techniques (use of fertilizers, irrigation with river water) may have on the rhizospheric microbiome of Vitis vinifera plants. Therefore, it is postulated the Cenophenoresistome as a novel methodology to evaluate complex communities’ global resistance against different antibiotics, by using and adjusting a serial of techniques traditionally applied to evaluate a monospecific population’s resistance against antibiotics (Vitek ® , ATB ® and disk diffusion methods). Likewise, the metabolic profile (CLPP: comunity level physiological profile) of bacterial communities is studied by Biolog ECO ® . In relation to the functional structure of the bacterial communities, it is observed that the metabolic profile (diversity, kinetics and CLPP) of unexploited soils differs from soils under anthropic influence. It is discussed the causes of resistance in the human clinic antibiotic treatment based on the agrarian management, especially with the contamination transmitted by irrigation water, which could be associated with changes in edaphic communities. The results obtained in the present study through two different approaches ( Cenophenoresistome and metabolic profiles) are consistent with each other, suggesting that both methods can be good bioindicators of the state of humankind-altered soils that host natural ecosystems. Likewise, the concept of Cenophenoresistome is proposed as a bioindicator of soil response to alteration processes, as well as a possible predictor of its evolution in edaphic remediation processes.
