Nutrient medium for cultivation of Bacillus subtilis IMV V-7023 was optimized by the method of the orthogonal Latin rectangles. Optimum concentrations were investigated in the medium of carbon source (15.0 g/l of molasses), nitrogen (2.0 g/l of corn extract) and content of phosphorus-containing inorganic salts (0.4 g/l). When growing this strain in periodic conditions at 28 degrees C, the value of oxygen mass transport in the liquid (0.4-0.6 g O2/l per 1 h) and the initial number of cells of each bacterial species was 1 x 10(6) cells/ml. The numbers of bacteria reached the maximum after 24 hours of cultivation and corresponded to 1.3 x 10(10) cells/ml. Nutrient medium that was optimized can be recommended for cultivation of B.subtilis IMV V-7023 in production conditions. The paper is presented in Russian.
We study the control of coherent light propagation through
Multiple-scattering media in the presence of measurement noise. In our
Experiments, we use a two-step optimization procedure to find the optimal
Incident wavefront. We conclude that the degree of optimal control of coherent
We show that by using two
Different sets of pheromones, a second-order co-evolved compromise between
Positive and negative feedbacks achieves better results than single positive
Feedback systems. The algorithm was tested against known NP-complete
Combinatorial Optimization Problems, running on symme...
Obesity contributes to increased risk for several chronic diseases including cardiovascular disease and type 2 diabetes. Xanthohumol, a prenylated flavonoid from hops (Humulus lupulus), was tested for efficacy on biomarkers of metabolic syndrome in 4week old Zucker fa/fa rats, a rode...
