“…Thus, the application of the two Bacillus strains stimulated the proliferation of other beneficial microorganisms. A previous study reported that the application of the biocontrol strain BL12 significantly increased the relative abundance of certain KEGG pathways [56], which was consistent with the predictions in the present study.…”

Lily Fusarium wilt disease caused by Fusarium spp. spreads rapidly and is highly destructive, leading to a severe reduction in yield. In this study, lily (Lilium brownii var. viridulum) bulbs were irrigated after planting with suspensions of two Bacillus strains that effectively control lily Fusarium wilt disease to assess their effects on the rhizosphere soil properties and microbial community. A high-throughput sequencing of microorganisms in the rhizosphere soil was performed and the soil physicochemical properties were measured. The FunGuild and Tax4Fun tools were used for a functional profile prediction. The results showed that Bacillus amyloliquefaciens BF1 and B. subtilis Y37 controlled lily Fusarium wilt disease with control efficacies of 58.74% and 68.93%, respectively, and effectively colonized the rhizosphere soil. BF1 and Y37 increased the bacterial diversity and richness of the rhizosphere soil and improved the physicochemical properties of the soil, thereby favoring the proliferation of beneficial microbes. The relative abundance of beneficial bacteria was increased and that of pathogenic bacteria was decreased. Bacillus abundance in the rhizosphere was positively correlated with most soil physicochemical properties, whereas Fusarium abundance was negatively correlated with most physicochemical properties. Functional prediction revealed that irrigation with BF1 and Y37 significantly upregulated glycolysis/gluconeogenesis among metabolism and absorption pathways. This study provides insights into the mechanism by which two Bacillus strains with antifungal activity, BF1 and Y37, antagonize plant pathogenic fungi and lays the foundation for their effective application as biocontrol agents.

“…Genome coverage of the obtained contigs was 50× on average. Automatic genome annotation was performed using the RAST (Rapid A using Subsystem Technology) server [12,13] implemented with RASTk [14], and with the NCBI Genome Automatic Annotation Pipeline (PGAP6.2, [7]) for the general genome annotation provided by NCBI RefSeq. Functional annotation was done by using PATRIC web resources [15].…”

“…The members of the genus are characterized by the formation of spherical swollen sporangia, containing L-lysine in their peptidoglycan cell wall, and by their inability to utilize traditional carbohydrates. Although reports about the biocontrol activity of Brevibacilli against plant pathogens are rare [ 5 , 6 , 7 ], the application of antimicrobial compounds with medical importance produced by Brevibacillus spp. has a long tradition.…”

We have previously reported the draft genome sequences of 59 endospore-forming Gram-positive bacterial strains isolated from Vietnamese crop plants due to their ability to suppress plant pathogens. Based on their draft genome sequence, eleven of them were assigned to the Brevibacillus and one to the Lysinibacillus genus. Further analysis including full genome sequencing revealed that several of these strains represent novel genomospecies. In vitro and in vivo assays demonstrated their ability to promote plant growth, as well as the strong biocontrol potential of Brevibacilli directed against phytopathogenic bacteria, fungi, and nematodes. Genome mining identified 157 natural product biosynthesis gene clusters (BGCs), including 36 novel BGCs not present in the MIBiG data bank. Our findings indicate that plant-associated Brevibacilli are a rich source of putative antimicrobial compounds and might serve as a valuable starting point for the development of novel biocontrol agents.

“…It can produce compounds that can prevent the growth of other organisms living in the same soil environment (Ray et al, 2020). The organism has proven to be effective in many biocontrol trial studies due to its ability to use different carbon sources and produces diverse bioactive metabolites (Ahmed et al, 2018, Ray et al, 2020Li et al, 2021). Cytobacillus species is known to synthesize several compounds with antagonistic activity towards other organisms in the soil environment which gives it an advantage in outcompeting other organisms (Xu et al, 2022).…”

Mosquito-borne diseases caused by infected mosquitoes like dengue fever, Zika fever, Chikungunya and malaria are spread to humans through biting causing disease epidemics all over the world. This indicates the necessity for new mosquito-borne disease control strategies in Saudi Arabia and internationally. This study evaluated the potential of local bacteria isolated from the soil of the Rahat region of Makkah, Saudi Arabia for the biocontrol of Aedes aegypti larvae, a major agent for the transmission of dengue fever. Soil samples were collected from the Rahat region, Makkah for the isolation of bacteria. The bacteria were evaluated for larvicidal activity against the larvae of A. aegypti. The bacteria that show toxicity to the larvae were identified using morphological and molecular characteristics. Four different strains of the bacteria with a toxicity towards A. aegypti larvae were isolated and identified. Two of the isolates (Brevibacillus centrosporus N8 and Cytobacillus species N7) caused 100% mortality in 24 h while the other two isolates (Escherichia coli N3 and Escherichia coli N4) caused at least 70% mortality. The findings of this study revealed the larvicidal activity of soil bacteria from the Rahat region, Makkah and could be a potential candidate for the biocontrol of mosquito vectors.
