dc.description.abstractVitamin A prevents eye problems, blindness and skin problems by strengthening the immune system. Vitamin E is a nutrient that has important roles in many areas such as skin health, eye health and hormonal order. Vitreoscilla hemoglobin (VHb) gives an advantage in later phases of grown conditions to cells. In this study, the intracellular and extracellular production of vitamin A and E in E. herbicola and its recombinant strains (vgb- and vgb+) in the three different M9 mediums with supplemented 0.1% glucose, 0.1% fructose and 0.1% sucrose was investigated. Additionally, the viable cell number and total cell mass (OD600) were measured by the host and the recombinant bacteria in these mediums. The VHb gene expression in E. herbicola enhanced vitamin A under different carbon conditionals. Especially, in the vgb + strain (carrying vgb gene) the production of total vitamin in 0.1% glucose medium was recorded as 0.14 µg/ml, while the production in fructose and sucrose media was recorded as 0.07 µg/ml. The production of intracellular vitamin E in the host strain (0.025 µg/ml) was about 13-fold (0.002 µg/ml) higher than vgb + recombinant strain in 0.1% fructose. The vgb + strain showed about 2-fold higher extracellular vitamin E production than the host strain.
