“…Whilst antagonist PS9.1 possesses some plant-growth-promoting and biocontrol compounds, rhamnolipids, pyoverdine, and rhizomide [ 22 , 32 ], the antagonist NWUMFkBS10.5 performed significantly ( p = 0.05) better than PS9.1 in all the treatments. This could be attributed to the action of its multiple plant-growth-promoting and biocontrol biosynthetic compounds, macrolactin, bacillibactin, mersacidin, bacilysin, surfactin, difficidin, iturin, and fengycin [ 21 , 33 ]. A large number of the Bacillus and Pseudomonas spp.…”

Based on in vitro assessments, molecular and chemical analysis, Pseudomonas fulva PS9.1 and Bacillus velezensis NWUMFkBS10.5 are candidate biocontrol agents for plant disease management including maize fusariosis, a disease caused by members of the Fusarium species. This in vivo study evaluated the bio-protective potential of the aforementioned rhizobacteria strains on maize against the proliferation of the pathogenic fungus Fusarium graminearum (Fg). The study results show that the bacterized plants were not susceptible to Fg aggression and the antagonists displayed the capability to proliferate in the presence of other likely competing microflora. The screen-house data also suggest that the presence of resident soil microbiota impacted the activity of antagonists (PS9.1 and NWUMFkBS10.5). This variation was recorded in the soil treatments (sterilized and unsterilized soil). In all the experimental periods, bacterized maize plants with or without Fg inoculation significantly (p = 0.05) grew better in unsterilized soil. Besides, during the experimental periods, all the consortia treatments with or without Fg infection regardless of the soil used demonstrated appreciable performance. The result of this study suggests that the microbial agents can actively colonize the surface of their maize plant host, improve plant growth, and suppress the growth of phytopathogens. Considering their overall performance in this screen-house evaluation, P. fulva PS9.1 and B. velezensis NWUMFkBS10.5 have potential for field applications. All safety issues regarding their use under field conditions and risks associated with their extended-release into the environmental will, however, be assessed prior to further bioformulation, field investigation, and scale-up.

“…fulva PS9.1 and B . velezensis NWUMFkBS10.5, were previously isolated from the maize rhizosphere, identified based on the 16S rDNA gene sequence analysis (accession numbers MF098600 and KX353617.1), and analyzed by genome sequencing [ 21 , 22 , 32 , 33 ]. The Fg pathogen was provided as a gift.…”

“…Recently, Adeniji and Babalola ( 2019 ) revealed that an in silico analysis of the strain genome by antiSMASH could permit to predict which antioxidant molecules could potentially be produced by a strain. In their study, they showed that Bacillus valezensis NWUMFkBS10.5 was potentially able to produce antioxidant molecules such as lampranthin-2, miraxanthin V, and 2-decarboxybetanidin.…”

Evaluation of Antiradical and Antioxidant Activities of Lipopeptides Produced by Bacillus subtilis Strains

et al. 2022

This study investigated the antiradical and antioxidant potential of the three families of lipopeptides (i.e., surfactin, mycosubtilin, and plipastatin/fengycin) produced by Bacillus subtilis strains. The antiradical/antioxidant activities of highly purified lipopeptides were studied in acellular models using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, superoxide anion (O2.-), hydrogen peroxide, (H2O2) and hydroxyl radical (HO.). At a lipopeptide concentration of 500 mg.L−1, the maximum inhibition of DPPH reached 22.88% (obtained for plipastatin). Moreover, the scavenging effects of O2.-, H2O2, and HO. at the highest concentration tested (250 mg.L−1) were found to be 6, 21, and 3% for surfactin, 19, 9, and 15% for mycosubtilin, 21, 18, and 59% for plipastatin, 21, 31, and 61% for the mixture of surfactin/plipastatin, and 13, 16, and 15% for the mixture of surfactin/mycosubtilin, respectively. These results showed that plipastatin was the best candidate due to its antioxidant activities.
