“…population in the soil treated by OMW suggests a suppressive environment for A. tumefaciens which could be related to the competition for nutrients, antibiosis and enhanced resistance of plants. This result was consistent with that reported by Kistner et al (2004), who demonstrated that there was a positive correlation between the concentration of fluorescent Pseudomonas spp. and resistance to microbial impact with the untreated OMW having the highest protection ability.…”

“…Consequently, an environmental soil suppressiveness against the plant pathogen Rhizoctonia solani was established and possibly also against other telluric pathogens. In the same way, Kistner et al (2004) found that the addition of OMW to hydroponic nutrient solutions provided an environment suppressing plant pathogens while favouring beneficials. In this work, we investigated the efficacy of OMW against a telluric pathogen A. tumefaciens.…”

“…Several researchers have demonstrated that only a few micro-organisms are able to survive in this by-product, because it contains various simple and complex phenolic compounds characterized by high antimicrobial activity (Capasso et al 1995;Kistner et al 2004). Some phytopathogenic bacteria like Pseudomonas syringae pv.…”

“…Many studies established that these wastes have a high fertilizer value when applied to the soil because of the high organic matter content and some mineral nutrient content (Paredes et al 1999). However, despite the potential agronomic value, soil amendment with OMW is also known for its antimicrobial activity (Capasso et al 1995;Kistner et al 2004). The incorporation of fresh OMW into the soil increases the number of soil micro-organisms and induces a change in the microbial population (Tardioli et al 1997).…”

Olive mill waste water (OMW) and some of its indigenous bacterial strains were tested in vitro and in planta for their efficacy against crown gall disease caused by Agrobacterium tumefaciens. OMW and polyphenols displayed a high level of antibacterial activity, however the volatile fraction was less efficient as only a bacteriostatic effect was observed. In pot experiments, the percentage of bitter almond rootstock showing symptoms of crown gall was significantly reduced with the dosage rate of OMW 1% as compared to the control (highly natural infected soil treated with water). Five indigenous bacterial strains isolated from OMW exhibited an antagonistic effect against the bacterium. Based on the gene 16S rRNA sequence analysis, one isolate showed 99.2% similarity to known sequences of Bacillus subtilis, one isolate demonstrated high percentage similarities (99.3%) to the genera Bacillus pumilis, and two isolates were associated with Stenotrophomonas maltophilia and Pseudomonas putida 100% and 99.6% similarities respectively. Among these bacteria, the strain B1 proved efficient against the soil borne pathogen in vitro and pot experiments. Our study in controlled conditions suggested that the addition of OMW to soil exerts significant disease suppressiveness against A. tumefaciens.

“…Thus, organic amendments might be relevant for the effective colonization of naturally occurring-antagonists for soilborne disease suppression. The application of olive mill waste water also selectively enhanced and sustained bacterial population of r-strategists and induced soil suppressiveness against Rhizoctonia solani (21), as well as created an environment favorable for beneficial microorganisms and suppressive to plant pathogens in hydroponics (20).…”

The effect of four amino acids, unutilizable by Ralstonia solanacearum, on tomato bacterial wilt (TBW) was tested in three Japanese soils. Results confirmed our previous findings that the addition (2.5 mg g −1 soil) of lysine and serine suppressed TBW, but that of tyrosine and valine did not. The number of the pathogen in non-rhizosphere soil, rhizosphere soil and the rhizoplane was markedly lower in the lysine and serine treatments than in the tyrosine and valine treatments, while the opposite result was obtained for the total bacterial population. Substrate-induced respiration analysis revealed that bacteria became more predominant in the amino acid treatments, especially in lysine. There were no apparent correlations between the microbial activities in soil and the disease index. PCR-DGGE targeting the 16S rRNA gene of the rhizoplane samples from lysine-added Nagoya, Fuchu and Iwate soils revealed 10, 1 and 2 unique bands, respectively, indicating shifts in bacterial community. DGGE patterns in the suppressive treatments belonged to the same cluster while the not suppressive treatments clustered differently. The lower disease incidence of TBW following lysine treatment is likely related to a specific bacterial community in the rhizoplane that developed on the addition of lysine.
