Usually positive, but some strains may not.
If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.

The result, in this case, is also positive.
The final result is positive.
Enterococcus faecalis is urea-positive, meaning it can hydrolyze urea in the urea broth test. This ability to break down urea into ammonia and CO2 can be detected by a change in pH indicator in the broth from yellow to pink.
Bright pinkish-red.
Urea can turn yellow due to the degradation of urea into ammonia and biuret under certain conditions, such as exposure to high temperatures or alkaline environments. This process can result in the formation of colored compounds, which can give the urea a yellow hue.

A positive test result for glucose is typically indicated by a color change to green, orange, or red, depending on the specific test method used.
Recording a positive result early is acceptable because some reactions may show positive results before the incubation time is completed due to accelerated enzyme activity. However, recording a negative result early for a urea hydrolysis test is not recommended because the reaction may need the full incubation period for urease activity to fully hydrolyze the urea and produce the correct result. This premature recording of a negative result may lead to inaccurate conclusions.
it is the color of urea
bluish color if pentose is present.
A positive result for dische diphenylamine test would be indicated by a deep blue color change in the solution. This color change indicates the presence of DNA, as dische diphenylamine reacts with deoxyribose sugars in DNA to produce a blue color.
Usually positive, but some strains may not.
A positive test result for starch is the formation of a blue-black color when iodine solution is added to the sample being tested. This color change indicates the presence of starch in the sample.
It's possible that it can be.
