Why did you refrigerate the gelatin cultures before observing them for liquefaction?
To indicate whether gelatin had been hydrolyzed by those cultures or not. If gelatin hydrolysis occurs, liquefaction occurs even afterrefrigerationto indicate a positiveresult. If gelatin hydrolysis does not occur, the gelatin will solidifies afterrefrigeration
Is staphylococcus aureus positive for gelatin hydrolysis?
Bacillus cereus is positive for gelatin hydrolysis. This bacteria is capable of hydrolyzing gelatin(a protein), thus, a nutrient gelatin medium inoculated with this bacteria will remain liquid when placed in an ice bath (don't agitate).the bacteria had proteases that is responsible for the hydrolysis of the gelatin..
Did gelatin give positive result with xanthoprotic test?
yes,it give positive test
Is staphylococcus aureus positive for gelatin?
Yes it is. This test can be used to differentiate between S. aureus (which is positive) and S. epidermidis (which is negative).
Will gelatin give a positive Biuret test?
yes Gelatin will have a positive biuret test. this is because it has an amide group which bends over the copper ion giving the colour pink or violet off to the visual eye.
What type of gelatin is in lucky charms?
halal gelatin
What is the pH of gelatin?

What is k-gelatin?
K-gelatin is gelatin made from kosher sources. Most kosher gelatin is made from either fish or seaweed.
What makes jello melt quickly?
Let's start with the point that what we really mean is, how to cause faster liquefaction, not quicker dissolving which, in the latter case, would mean how to make the dry and liquid ingredients of the gelatin to go into solution quicker. Uncannily, however, the answer is the same as to either question. Gelatin is refrigerated or kept on ice in order to prevent its becoming too soft, and eventually reverting to liquid form at "room" temperature. Following from that, the application of heat (that being ambient or artificially applied heat) will, conversely, cause a gelatin's reversion to liquid form (from whence it originated). Accordingly, the process of reversion to liquid will be accelerated by increase in the application of heat, i.e., will be hastened in proportion to the temperature to which the gelatin is subjected. In effect, the process of preparing a gelatin is reversible.
How do you make soft candies using gelatin?

Is gelatin a homogeneous or heterogeneous mixture?
