How does Saccharomyces cerevisiae produce ethanol? S. cerevisiae is the most employed yeast for ethanol production at industrial level though ethanol is produced by an array of other yeasts, bacteria, and fungi. Ethanol has been produced from wide range of substrates such as molasses, starch based substrate, sweet sorghum cane extract, lignocellulose, and other wastes. […]
How many volts is a 3 phase?
How many volts is a 3 phase? What’s the difference between single phase and three phase? Electricity is either connected at 230 or 240 volts (single-phase, which accounts for the majority of domestic situations), or 400 and 415 Volts (three-phase). How many cycles does 3 phase current have? In a three-phase system, three circuit conductors […]
What is the best stereospecific conformation for E2 elimination?
What is the best stereospecific conformation for E2 elimination? In an E2 elimination, the new π bond is formed by overlap of the C-H σ bond with the C-X σ* anti-bonding orbital. The two orbitals have to lie in the same plane for best overlap. E2 elimination takes place from the anti-periplanar conformation, as this […]
What causes an engine to knock?
What causes an engine to knock? The knocking sound often occurs when the air-fuel mixture is incorrect, which causes the fuel to burn in uneven pockets rather than uniform bursts. Left untreated, it can cause damage to the piston and cylinder wall. A knocking sound can also be caused by a lack of lubrication in […]
How is the amperage adjusted on a FCA welding machine?
How is the amperage adjusted on a FCA welding machine? how is the amperage adjusted on a FCA welding machine? changes in the wire feed speed automatically change the amperage. How do you adjust amperage on a welder? Pro Tip: A good rule of thumb for setting your stick welder (SMAW) to the approximate right […]
Which crystal structures are close packed?
Which crystal structures are close packed? It turns out that face-centered cubic and hexagonal close-packed crystal structures pack atoms equally tightly. Some metals with hexagonal close-packed crystal structures include cobalt, cadmium, zinc, and the α phase of titanium. What are closed packed structures? The term “closest packed structures” refers to the most tightly packed or […]

TV and Media Equipment: 4 percent. What uses more electricity AC or heater? The simple answer to your first question is yes, because heating uses […]
Does ideal vapor compression refrigeration cycle involve any internal irreversibility?
Does ideal vapor compression refrigeration cycle involve any internal irreversibility? The ideal compression refrigeration cycle is not an internally reversible cycle, since it involves throttling which is an irreversible process. What are the main components of Vapour compression refrigeration system? 3.4. 2 Vapor compression refrigerators. A detailed description of the vapor compression refrigeration is available […]

What is the purpose of liquid limit test?
What is the purpose of liquid limit test? Value of liquid limit is used to classify fine grained soil. It gives us information regarding the state of consistency of soil on site. Liquid limit of soil can be used to predict the consolidation properties of soil while calculating allowable bearing capacity & settlement of foundation. […]
