“…This aspect can be a remarkable problem because, in recent years, the need to find highly efficient biofertilizers has led to the search for bacterial genera that, despite presenting excellent mechanisms for promoting plant growth, have characteristic pathogenicity such as that observed with Burkholderia, Enterobacter, Ochrobactrum, Ralstonia, Staphylococcus, Stenotrophomonas, Serratia or Klebsiella [49]. This aspect has been frequently considered when inputs with a high microbial load are used, such as sewage sludge, compost tea or compost, in which the population composition of microorganisms found in the product is not controlled and which often incorporates pathogenic taxa with the negative implications that they present for the health of the applicator and, mainly, for the final consumer; this is especially relevant when referring to a product for fresh consumption [50,51]. In addition, in recent years, research seems to have focused on genera such as Serratia or Pantoea because they have excellent mechanisms for promoting plant growth, such as phosphate solubilization, phytohormone production and nitrogen fixation, in some cases [13,52]; however, their use is subject to their pathogenic nature, as some authors have mentioned [53], being aware that the benefits of their use are fewer than the negative implications they present with respect to human health.…”
