Switchgrass is used for ethanol production. The composition of the switchgrass is 37% cellulose, 24% xylan, 3% galactan, 4% arabinan, 20% lignin, 7% extractives, and 5% ash. A dilute acid pretreatment method is applied to the switchgrass before enzymatic hydrolysis and fermentation. The pretreatment hydrolyzes 10% hexosan and 90% pentosan into monomeric sugars. Approximately 30% of the hydrolyzed pentoses further react & are decomposed to furfural. Assume that there is no decomposition of the hydrolyzed hexoses. Further Assume that lignin, extractives, and ash do not change during the pretreatment. • How much of each lignocellulosic sugar (glucose, xylose, galactose, and arabinose) is produced when pretreating 1,000 kg (dry matter) switchgrass? How much furfural is formed? • Is water consumed or produced in these pretreatment hydrolysis and dehydration reactions? How much in each?
You are attempting to create an E. coli mutant that lacks the enzyme to convert 1,3- Bisphosphoglycerate into 3-Phosphoglycerate. Normally you grow your E. coli in a medium with glucose as its only carbon source. What other compound would you need to add to your normal medium in order to allow your mutant E. coli to grow? Pentose phosphate cycle Pentose phosphate Sedobestudose 2 phosphate Enthrise-4phosphate Glyceraldehyde 3phosphate Fructose Erythrose Glycolysis Glucose phosphate Fructose-6-phosphate Fructose 1.6 diphosphate Glyceraldehyde-3-phosphate Dihydroxyacetone phosphate 1,30iphosphoglycerate 3Phosphoglycerate Dynwate 2Phosphoglycerate Phosphomolywate Acetyl coenzyme A- Crate Isocrate 20 Oxaloacetate, TCA cycle Fumarate Succinate You don't need to add a second carbon source for your mutant to grow Pyruvate Succinyl coenzyme A
A “pulse-chase” experiment using 14C-labeled carbon sources is carried out on a yeast extract maintained under strictly anaerobic conditions to produce ethanol. The experiment consists of incubating a small amount of14C-labeled substrate (the pulse) with the yeast extract just long enough for each intermediate in the fermentation pathway to become labeled. The label is then “chased” through the pathway by the addition of excess unlabeled glucose. The chase effectively prevents any further entry of labeled glucose into the pathway.(a) If [1-14C]glucose (glucose labeled at C-1 with 14C) is used as a substrate, what is the location of 14C in the product ethanol? Explain.(b) Where would 14C have to be located in the starting glucose to ensure that all the 14C activity is liberated as 14CO2 during fermentation to ethanol? Explain.
Besides the final product, what other important difference is there between the fermentation pathways of E. coli? Or, in other words, for what purpose does the cell activate the fermentative pathways when there is lack of oxygen?
Yeast cells are added to a 3.0 L batch bioreactor so that the initial cell concentration is [X]. = 1.3 g cells / L. The growth mediğim in the reactor, which is well-mixed so the cells have access to all nutrients, contains 150 g CELL DATA ribose (C5H10O5, MW 150), 75 g ammonia (NH3, MW 17), and 85 g oxygen (O2, MW 32).

You inoculate two test tubes with the same amount of identical growth medium and with the same number of identical yeast cells and grow these cells under identical conditions except for the presence or absence of oxygen. b) The cells of both cultures convert glucose to pyruvate via glycolysis, and then further metabolize pyruvate. Are the cells of both cultures able to obtain the same amount of ATP from glycolysis? Explain. Under anaerobic conditions, the carbon from pyruvate will ultimately be found in which molecule? Under aerobic conditions, the carbon from pyruvate will ultimately be found in which molecule?

Please answer the following correctly: i) Salt is often used as a food preservative to prevent bacterial and fungal growth (for example, in country ham). But salt is also important to enhance the flavor of bread when added in small amounts. At what concentration does salt begin to inhibit yeast fermentation? j) Does the food preservative Na benzoate inhibit cellular respiration? k) How do fermentation rates compare for baker's yeast (saccharomyces cerviside) and sourdough yeast, (candida milleri) in different pH environments? l) How do fermentation rates compare for yeast used in brewing most beers (S. cervisiae) and lager (S. pastorianus - a hybrid between S. cervisiae and S.eubaymus)?
Figure 1. + Η NaOH, H2O (pKa = 15) heat H + "Да H A pKa = 20 B pKa = 17 D The aldol condensation reaction in Figure 1 is an amazing example of how unfavorable equilibrium processes can be manipulated to generate product in good yields. In this case, the major product is the self-condensation product, D. The next most abundant product is the crossed aldol product, C. There are 2 other less favorable products that could form but are not shown in Figure 1. Draw a plausible electron pushing mechanism to show how product C is formed. Remember, if an alow Stans mom an electron pair, you must explicitly draw those electrons in.
