“…In the present study, 18 isolates out of the 25 tested, belonging to Bacillus, Enteroabacter, Klebsiella and Chrysobacterium, were shown able to solubilize inorganic forms of phosphorous. Bacillus strains were reported to have this capacity [64,65]. The phosphate solubilization ability recorded in some tomato-associated rhizobacteria in the present study is in line with other investigations performed using Bacillus [66], Enterobacter and Klebsiella species [64,[67][68][69].…”

Due to the limited knowledge in Tunisia on the nature of native tomato-associated rhizobacteria and their ability to suppress root rot diseases in tomato, the main objectives of the present study were i) to isolate bacterial isolates from tomato rhizosphere and to assess their ability to suppress the in vitro growth of S. sclerotiorum and R. solani, ii) to identify and characterize the most effective ones in suppressing both pathogens, and iii) to assess their potential to produce antifungal and plant growth-promoting compounds.

“…Further characterization of B. amyloliquefaciens HTI-19 will be particularly helpful in food industries. It has been reported that B. amyloliquefaciens strains were able to inhibit the growth of a variety of fungal pathogens because of their ability to produce a vast array of antibiotics, such as bacillomycin, zwittermicin, bacilysin, difficidin, and fengycin [51,52].…”

This study aimed to isolate, identify, and evaluate the probiotic properties of Bacillus species from honey of the stingless bee Heterotrigona itama. Bacillus spp. were isolated from five different H. itama meliponicultures, and the isolates were characterized through Gram-staining and a catalase test. Tolerance to acidic conditions and bile salt (0.3%), hydrophobicity, and autoaggregation tests were performed to assess the probiotic properties of the selected isolates, B. amyloliquefaciens HTI-19 and B. subtilis HTI-23. Both Bacillus isolates exhibited excellent antimicrobial activity against both Gram-positive and Gram-negative bacteria and possessed significantly high survival rates in 0.3% bile solution for 3 h. Their survival rates in acidic conditions were also comparable to a commercial probiotic strain, Lactobacillus rhamnosus GG. Interestingly, the hydrophobicity and autoaggregation percentage showed no significant difference from L. rhamnosus GG, a commercial probiotic strain. The results from this study suggest that B. amyloliquefaciens HTI-19 and B. subtilis HTI-23 isolated from stingless bee honey have considerably good probiotic properties. Therefore, more studies should be done to investigate the effects of these bacteria cultures on gastrointestinal health.

“…E. nigrum is known as biological control agent against fungal pathogens such as B. cinerea (Alcock et al, 2015 ) or Monilinia laxa on fruits surface (Larena et al, 2005 ). Bacillus pumilus is also known to inhibit several plant pathogens such as Fusarium solani on tomato (Ajilogba et al, 2013 ) or fungal pathogens responsible for poplar canker (Ren et al, 2013 ). P. vagans and P. agglomerans have demonstrated strong beneficial activities as biological control of bacterial diseases (Johnson and Stockwell, 1998 ; Braun-Kiewnick et al, 2000 ).…”

The aim of this work was to investigate the diversity of endogenous microbes from wheat (Triticum aestivum) and to study the structure of its microbial communities, with the ultimate goal to provide candidate strains for future evaluation as potential biological control agents against wheat diseases. We sampled plants from two wheat cultivars, Apache and Caphorn, showing different levels of susceptibility to Fusarium head blight, a major disease of wheat, and tested for variation in microbial diversity and assemblages depending on the host cultivar, host organ (aerial organs vs. roots) or host maturity. Fungi and bacteria were isolated using a culture dependent method. Isolates were identified using ribosomal DNA sequencing and we used diversity analysis to study the community composition of microorganisms over space and time. Results indicate great species diversity in wheat, with endophytes and pathogens co-occurring inside plant tissues. Significant differences in microbial communities were observed according to host maturity and host organs but we did not find clear differences between host cultivars. Some species isolated have not yet been reported as wheat endophytes and among all species recovered some might be good candidates as biological control agents, given their known effects toward plant pathogens.
