Evaluation of Indigenous Bacillus Strains from Asian Fermented Foods for Probiotic Properties.

Bacillus species hold particular importance due to their versatile enzymatic repertoire and ability to synthesize diverse bioactive metabolites. In this study, two fermented food-derived strains, Bacillus siamensis BB3 (from douchi) and Bacillus velezensis TMA10 (from tapai) were evaluated for their probiotic, anti-microbial and functional potentials. Both strains exhibited desirable probiotic characteristics, including desirable tolerance to simulated gastric and intestinal conditions, with BB3 showing greater acid tolerance than TMA10. Safety assessments confirmed the absence of hemolytic activity, virulence factors and antibiotic resistance genes. Whole genome sequencing showed that the strains harbored genomic sequences for a wide range of metabolites, including non-ribosomal peptides and polyketides. Ethyl acetate (EtOAc) extracts from both strains demonstrated broad-spectrum anti-microbial activity against several indicator microorganisms, including Listeria grayi, Bacillus cereus, Serratia marcescens, Escherichia coli, and Pseudomonas aeruginosa, with TMA10 additionally inhibiting MRSA and Streptococcus mutans. Liquid Chromatography-Mass Spectrometry profiling identified key anti-microbial compounds, namely surfactins, macrolactins, bacillaene from BB3 and TMA10. In addition, difficidins were also detected from TMA10. Genomic analysis further indicated diverse carbohydrate utilization capacities; both strains encoded pathways for sucrose, raffinose-family oligosaccharides and lactose metabolism, while TMA10 possessed pathways for trehalose, glucomannan and arabinoxylan degradation. Both strains also showed anti-oxidant activity, with enhanced effects observed in their cell-free supernatants and heat-killed preparations. Overall, these findings highlight BB3 and TMA10 as promising candidates for the development of fermented food-derived Bacillus probiotics and functional cultures with anti-microbial, anti-oxidant, and broad carbohydrate-utilization capabilities.

Spatially resolved multi-omics analysis of indigenous Bacillus-fortified high-temperature Daqu.

Layer-dependent patterns associated with indigenous Bacillus fortification on high-temperature Daqu remain unclear. Here, six indigenous functional Bacillus strains were combined to fortify Daqu at three inoculation levels (QH4, QH5, QH6), with non-fortified as the control (CK). Upper, middle, and lower shelf-layer samples were profiled by physicochemical measurements, volatilomics, organic acid analysis, untargeted metabolomics, 16S/ITS amplicon sequencing, and metagenomics. PERMANOVA showed significant effects of treatment, spatial layer, and their interaction on physicochemical, volatile, bacterial, and fungal profiles (P = 0.001). Among the three inoculation levels, QH5 showed the most balanced performance: QH5_M exhibited the highest observed mean peak temperature (63.3 °C; +4.5 °C relative to CK_M), and its group-mean temperature remained ≥ 60 °C for seven consecutive days. Multi-omics analyses indicated coordinated, non-linear, and layer-dependent differences associated with indigenous Bacillus fortification, with QH5_M showing the most pronounced combined thermal, pyrazine, substrate, microbial, and predicted functional profile. These findings indicate that moderate indigenous Bacillus fortification was associated with distinct layer-dependent thermal and flavor profiles and coordinated microbial, metabolic, and predicted functional differences.
