A simple synthesis route is presented to obtain single BiFeO3 and mixed BiFeO3/Fe2O3/Bi2Fe4O9 photocatalysts. The obtained samples were characterized to analyze their structural, magnetic, optical and physical–chemical properties. The role of additional phases, i.e. Bi2Fe4O9 and Fe2O3 in the BiFeO3 structure, was analyzed by investigating sunlight-driven water oxidation and degradation of different dye pollutants. The achieved results suggest formation of BiFeO3/Fe2O3/Bi2Fe4O9 heterojunction-like interfaces, that induce lower e−/h+ recombination rate, thus enhancing photoactivity than bare BiFeO3. Additionally, BiFeO3/Fe2O3/Bi2Fe4O9 has exclusive feature of being magnetically separated from treated media and its stability was demonstrated for at least 3 cycles of dye degradation.

Here, we reported a novel secreted protein elicitor PeBL2 from Brevibacillus laterosporus A60, which can induce hypersensitive response in tobacco (Nicotiana benthamiana). The ion-exchange chromatography, high-performance liquid chromatography (HPLC) and mass spectrometry were performed for identification of protein elicitor. The 471 bp PeBL2 gene produces a 17.22 kDa protein with 156 amino acids containing an 84-residue signal peptide. Consistent with endogenous protein, the recombinant protein expressed in Escherichia coli induced the typical hypersensitive response (HR) and necrosis in tobacco leaves. Additionally, PeBL2 also triggered early defensive response of generation of reactive oxygen species ($H_2O_2$ and $O_2{^-}$) and systemic resistance against of B. cinerea. Our findings shed new light on a novel strategy for biocontrol using B. laterosporus A60.
