It can be good, depending on what it is you are fermenting. Mead is made from fermented honey, for instance, and if you like mead, I guess that is a good thing. A great number of alcoholic drinks are either made from or made better by fermentation. Often fermentation can improve the taste of certain things, but sometimes it can ruin other things.
Fermentation is a chemical change.
Oxygen is not needed in fermentaion.
continuous and discontinuous fermentations
Alcholic fermentation and Lactic Acid fermentation.
Alcholic fermentation and Lactic Acid fermentation.
1.Alcoholic fermentation 2.Lactic fermentation
firstly you take beer and split. then you can add oil to it then yah. thats it. thats the stages in fermentaion
they dont use oxygen as the final acceptor! basically they are anerobic processes
In alcoholic fermentation, yeast converts sugars into ethanol and carbon dioxide. In lactic acid fermentation, bacteria convert sugars into lactic acid.
Alcoholic fermentation is the chemical reaction between an enzyme, zymaze (secreted by yeasts) and sugar to produce ethyl alcohol and carbon dioxide. It is the reaction used to make beer, wine and spirits.
respiration is in presence of oxygen which leads to complete breakdown of sugar yielding many times more energy than in fermentation which is in absence of oxygen
The API 20E System is a miniatuized version of conventional tsts that is used for the identification of members of the family Enterobacteriaceae and other gram-negative bacteria. This system utilizes a plastic strip with 20 separated compartments. Each compartments consists of a depression, or cupule, and a small tube that contains a specific dehydrated medum. After you inoculated each compartment with an unknown bacteria, a reaction will occur within 24 hours. The results of each reaction are tabulated and then given a number based on the results. The unknown bacteria is identified by searching through a book, Analytical Profile Index (may be in other book), and searching for the number corresponding to your unknown.The test consists of the following:ONPG: galactosidaseADH: Arginine DiHydolaseLDC: LysineDeCarboxylaseODC: Ornithinine DeCarboxylaseCIT: Citrate utilizationH2S: Hydogen sulfide productionURE: UreaaseTDA: Tryptophane DeAminaseIND: Indole ProductionVP: acetoin production (Voges Proskauer)GEL: GelatinaseGLU: fermentaion / oxidation (Glucose)MAN: fermentaion / oxidation (Mannitol)INO: fermentaion / oxidation (Inositol)SOR: fermentaion / oxidation (Sorbitol)RHA: fermentaion / oxidation (Rhamnose)SAC: fermentaion / oxidation (Saccharose)MEL: fermentaion / oxidation (Melibiose)AMY: fermentaion / oxidation (Amygdalin)ARA: fermentaion / oxidation (Arabinose)Supplemental Test also may be done with the API testOXI:NO2:N2 GAS:MOT:MAC:OF-O:OF-F:The reactions of each compartment are given a (+) or (-). Each compartment has a corresponding points. If a reaction for a certain compartment, like GLU, is possible then the points are counted.Every 3 compartment (or test) is given a number. The points of every 3 set is 1, 2, and 4 (in order)... Do not get mixed up with points and number. Each test has a corresponding points and Every 3 tests is given a number based on the results...For example:ONPG (1), ADH (2), and LDC (4)If ONPG and LDC are positive and ADH reaction is negative, then the number given to this set is 5 (1pt from ONPG and 4pt from LDC; No point is given to ADH because the result is negative)THERE SHOULD BE 9 NUMBERS[27 tests/compartments divided into 3 groups each is 9]A test result for a specific bacteria of Eshcerichia coli (E. coli) is+ - + + - - - - + - - + + - + + - + - + - + - + + + +5 1 4 4 5 5 2 5 7The number is 514455257An important thing to remember is that they have a lot of bacteria. Some bacterias have different strains, so there may be more than 1 number that identifies to be E. coli. It's just they are different strains of E. coliInformation taken from Benson's MICROBIOLOGY APPLICATIONS Tenth edition by Alfred E. BrownPosted by 13K
