For the production of a secondary metabolic by Streptomyces coelicolor, a fed batch was performed. At the end of the single batch phase, the following conditions were reached in the reactor: V=10000L, cell concentration X=10g/L and product concentration P=0.1g/L. The feeding was then started with constant flow F= 200L/h, for 100h. Knowing that the substrate concentration in the feeding medium was SF= 80g/L and in the fermentation medium it was practically null, calculate: a) The final concentration of cells and product b) If the reactor were fed with a constant dilution rate (D), what should be the value of D used to reach the same cell concentration obtained in the situation with constant flow? μp= 0.01 g of product/ (g of cells.h) Y x/s = 0.15g cells/g of substrate

Two flasks of E. coli are grown in batch culture in the same medium (2% glucose and amino acids; no nitrate) and at the same temperature (378C). Culture #1 is well aerated. Culture #2 is anoxic. After 16 hours the following observations are made: ■ Culture #1 has a high cell density; the cells appear to be in stationary phase, and the glucose level in the medium is reduced to 1.2%. ■ Culture #2 has a low cell density; the cells appear to be in logarithmic phase, although their doubling time is prolonged (over 1 hour). The glucose level is reduced to 0.2%. Why does culture #2 have so little glucose remaining relative to culture #1, even though culture #2 displayed slower growth and has less biomass?
Menaquinones is produced by Flavobacterium meningosepticum via submerged fermentation with 60% working volume in 30-L fermentation. To obtain the crude menaquinones, the fermentation medium is centrifuged at 12,000 rpm for 15 minutes. The vacuum-freeze dried particles are crushed and collected. After that the samples are treated with methanol for 20 minutes. To remove polar lipid compounds from bacterial cells, HZ816 macroporous adsorption resin column is used with methanol-dichloromethane (l:1) as mobile phase and flow rate of 0.75 mL/min. Rotary evaporation at 500 C is carried out to concentrate the eluent. After that, the concentrated sample is purified with Bio-BeadsTM S-X3 to remove components without UV absorption. To obtain the homolog purified menaquinones, RP-C18 column is used. Recrystallization is carried out to obtain pure crystalized menaquinones. Answer the following: Indicate how to obtain the sample in the methanol solvent. Three different chromatography are used in…

Examine the graph shown below of a liquid culture growth curve for S. pneumoniaegrowing in minimal broth containing both glucose and lactose in equal concentrations as a potential carbon source. Answer the following questions: a) Name the growth phases labelled as I, II and III, explain the observed pattern of growth at each of these stages in the curve b) Where would the concentration of cAMP be low and why? c) In what phase would β-galactosidase be high and why? d) What kind of overall growth pattern does this curve illustrate?
Nitrate reduction test can be used to differentiate between Pseudomonads and Enterobacteriaceae. You inoculated your Nitrate broth with your unknown; after incubation, you added 5 drops of reagent A and 5 drops of reagent B. You observe a red color within 2 minutes. Is this a + or a - reaction? Assuming you did not get a red color, you then added a pinch of Zinc and this time tou obtained a red color. What does this mean?

Sweet sorghum juice is used as sole carbon source for ethanol production by Saccharomyces cerevisiae. The overall in situ sterilisation duration is 40 minutes at 120 0C for a pilot reactor (50 L) which is filled with 60% of working volume. The non-sterile medium consists of 3.28 x 106 contaminants L-1. During the autoclaving process, you have noticed that the time taken for heating and cooling are 18 minutes and 15 minutes, respectively. As a process engineer, explain if you agree with this sterilisation practice by using quantitative analysis.
Enterobacter aerogenes inoculated into a glucose fermentation tube often gives a weak acid result (orange-yellow) with a very large bubble in the Durham tube. If it ferments glucose, why might the tube not turn very yellow?
