Kombucha requires two fermentation steps. The first one is partly aerobic and partly anaerobic. The aerobic growth occurs because the kombucha is allowed to brew exposed to oxygen. Where is the anaerobic growth occurring in the first fermentation step?
The second fermentation step is the step in which we add the kombucha to a sealed bottle therefore I'm confused as to where it can occur before we seal it.
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?

Six bottles were prepared, and each bottle, except for the positive control, lacked a certain micronutrient. In the positive control, all nutrients were provided. Unexpectedly, the control setup still showed symptoms of micronutrient deficiency. Students later on found out that the relative humidity in the room was very high and transpiration was affected. 1.Explain the appearance of these symptoms in the positive control set-up in lieu of the importance of transpiration? 2.Theoretically, how will thermoregulation of tomato plants be affected if transpiration will not occur 3.
