Two novel strains, J116-2(T) and J116-1, were isolated from forest soil and were taxonomically characterized by a polyphasic approach. Both strains were yellow-coloured, Gram-stain-negative, strictly aerobic, non-motile and rod-shaped bacteria. The strains were non-sporulating, catalase-positive and oxidase-negative. Strains J116-2(T) and J116-1 were able to grow at 20-32 °C, pH 6.0-8.5, and 0-0.5 % (w/v) NaCl concentration. Based on 16S rRNA gene sequence analyses, strains J116-2(T) and J116-1 formed a distinct lineage within the family Chitinophagaceae of the phylum Bacteroidetes and were closely related to genera Taibaiella (89...

A novel Gram-stain-positive, motile and facultatively anaerobic strain, designated NC2-31(T), was isolated from sediment from the coast of Weihai, PR China. Optimal growth occurred at 37 °C, pH 7.5 and with 2.0-3.0 % (w/v) NaCl. MK-7 was the major respiratory quinone. Meso-diaminopimelic acid was a diagnostic diamino acid in the peptidoglycan. The major polar lipids of NC2-31(T) were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). The genomic DNA G+C content of the strain was 46...

Menaquinone-7 (MK-7) is the key form of vitamin K used as a dietary supplement and its production revolves around Bacillus subtilis natto. Current fermentation strategies, which suggest static fermentations without aeration and agitation, can be problematic for large scale MK-7 production due to biofilm formation. The use of biofilm reactors, therefore, is proposed in the present study, which could utilize both agitation and aeration without interrupting MK-7 secretion. In this study, biofilm reactors were constructed using the selected plastic composite support (PCS) and B...

One of the major issues associated with industrial production of menaquinone-7 (MK-7) is the low fermentation yield. In this study, we investigated the effect of iron oxide nanoparticles coated with 3-aminopropyltriethoxysilane (IONs@APTES) on the production of MK-7 using B. subtilis (ATCC 6633). Decoration of B. subtilis cells with IONs@APTES significantly enhanced both MK-7 production and yield. An approximately two-fold increase in MK-7 production (41 mg/L) was observed in the presence of 500 µg/mL IONs@APTES, as compared to MK-7 production using untreated bacteria (22 mg/L)...

Two strains of bacteria, designated J107-1(T) and J107-2, were isolated from farmland soil. Cells were aerobic, Gram-stain-negative, catalase- and oxidase-positive, non-motile, non-spore-forming, coccoid rod-shaped and yellow-pigmented. Flexirubin-type pigments were absent. Both strains hydrolysed casein and tyrosine. Strains could grow at pH 9.0 and at 42 °C. A phylogenetic analysis based on its 16S rRNA gene sequence revealed that strains J107-1(T) and J107-2 formed a lineage within the phylum Bacteroidetes that was distinct from various members of the family Chitinophagaceae, including Ferruginibacter paludis HME8881(T) (89...
