Advances in Menaquinone-7 Production by Bacillus Subtilis Natto: Fed-batch Glycerol Addition
Menaquinone-7 was produced by fermentation mainly using Bacillus subtilis species. Due to the low concentration of menaquinone-7 in fermentation processes and the associated expense of recovering the menaquinone-7, it was desirable to improve the fermentation concentration. The aim of this study was to determine the effect of fed-batch glycerol addition in the production of menaquinone-7 during...
متن کاملSynthesis and Application of Amine Functionalized Iron Oxide Nanoparticles on Menaquinone-7 Fermentation: A Step towards Process Intensification
Industrial production of menaquione-7 by Bacillus subtilis natto is associated with major drawbacks. To address the current challenges in menaquione-7 fermentation, studying the effect of magnetic nanoparticles on the bacterial cells can open up a new domain for intensified menqainone-7 process. This article introduces the new concept of production and application of l-lysine coated iron oxide ...

متن کاملHeme and menaquinone induced electron transport in lactic acid bacteria
BACKGROUND For some lactic acid bacteria higher biomass production as a result of aerobic respiration has been reported upon supplementation with heme and menaquinone. In this report, we have studied a large number of species among lactic acid bacteria for the existence of this trait. RESULTS Heme- (and menaquinone) stimulated aerobic growth was observed for several species and genera of lact...
متن کاملStrain and plastic composite support (PCS) selection for vitamin K (Menaquinone-7) production in biofilm reactors.
Menaquinone-7 (MK-7), a subtype of vitamin K, has received a significant attention due to its effect on improving bone and cardiovascular health. Current fermentation strategies, which involve static fermentation without aeration or agitation, are associated with low productivity and scale-up issues and hardly justify the commercial production needs of this vitamin. Previous studies indicate th...
