A central composite design (CCD) was used to obtain a model describing the relationship between glucose, total nitrogen, and the maximum cell dry weight in the culture broth with fed batch fermentation in a 5 L fermentor.
In batch-fed systems, the maximum open circuit voltage (OCV) was between 700 and 800 mV and the maximum cell potential difference was higher than 600 mV with an external resistance of 100 Ω.
Next, a MILP problem is sequentially solved for all metabolites to attain the maximum cell growth at various flux-sum perturbations between the calculated minimal and maximal values.
The maximum path loss determines the maximum cell coverage.
The maximum cell density recorded was 6.4 × 106 cell/mL (0.35 g/L), while the specific growth rate, μ was 0.195 day−1 (calculated between 4th and 8th day).
Except for the maximum cell density reached by the cultures (Nmax), all the parameters compared were significantly different between both strains.
In the case of advection of a concentration, repair keeps the newly computed concentration in a cell between the maximum and minimum concentrations in neighboring old cells, thus guaranteeing at least that the new concentration is between zero and one.
Under anaerobic conditions, differences in growth rate and maximum cell density between the mutant and wild-type strains were statistically insignificant when one of the following electron acceptors was used; fumarate (20 mM), nitrite (1 mM), thiosulfate (3 mM), TMAO (20 mM), MnO2 (5 mM), ferric citrate (10 mM), and cobalt III -EDTA (200 μM) (data not shown).
We optimized the conditions for beta-propiolactone (BPL) inactivation of the bacterial suspensions, establishing a maximum cell density of OD600 between 27 and 30, with a BPL concentration of 1 4000 (v/v) at 150 rpm and 4 °C for 30 h.
The procedure to adjust the transmission implies reducing the maximum transmission power considering the difference in propagation losses between the maximum coverage distance of the LTE cell--given by the 95%-tile of the distance of located users, extracted from off-line statistics--and the maximum distance where the opportunistic resource can be used.
