Abstract

We report photoemission and near-edge x-ray absorption fine structure measurements of the occupied and unoccupied valence electronic states of the regular surface layer of Bacillus sphaericus, which is widely used as the protein template for the fabrication of metallic nanostructures. The two-dimensional protein crystal shows a semiconductorlike behavior with a gap value of approximately 3.0 eV and the Fermi energy close to the bottom of the lowest unoccupied molecular orbital. We anticipate that these results will open up new possibilities for the electric addressability of biotemplated low-dimensional hybrid structures.

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.
