Safety assessment of potential psychrotrophic bacterial strains. A In-vitro cytotoxicity of bacterial consortium towards human keratinocyte (HaCaT) cell lines. The three concoctions of bacterial consortia (intact bacterial consortia, extracellular supernatant and intracellular lysate) were assessed for their cytotoxic effects against HaCaT cell lines and were non-cytotoxic at various concentrations. B In-vitro phytotoxic effect of selected psychrotrophic bacterial strains on Pisum sativum var AS10 seeds. All the selected strains were non-phytotoxic towards seed germination except for the LUR25 strain. The different letters in the figure describes the statistical difference (p < 0.05) calculated by Tukey post hoc tests among the samples. *Represent a significant difference
