28 Applied and Industrial Microbiology -- Part 10
The four are caused by parasites.
Giardiasis is a disease.
Refer to Diseases in Focus 25.5 to complete the table for amebic dysentery, which has blood and mucus.
From the time of preparation to the time of ingestion.
Water occurs when food is mishandled.
Antimicrobial agents are not effective in cooking.
The organisms could be present during preparation or after cooking.
The table can be completed by referring to Diseases in Focus 25.2.
Refer to Diseases in Focus 25.3 and 25.4 for the answer to this question.
All organisms need Phosphorus.
Personal hygiene and medical procedures can cause urinary tract infections.
They are caused by diseases.
The proximity of the anus to the urethra and the short length of the urethra can cause urinary bladder infections in females.
There are portals of entry from the lower urinary tract.
Refer to Diseases in Focus 26.2 and 26.3 to complete the table.
Improved aeration and mixing results in improved cell growth and densities.
The process reproducibility is improved.
Methane can be used to produce products or accomplish a process, while industrial microbiology is the science of using organisms to make alcohol and hydrogen.
Industrial microbiology is produced by respiration.
Eliminating disease-causing organisms is the goal of commercial sterilization.
The berries have acid in them.
Lactic acidbacteria grow in the interior of the curd to ripened hard cheese.
Soft cheese is ripened by molds on the outside of the curd.
Water is also needed for hydrolysis.
Larger culture volumes can be grown with a bioreactor.
Monitoring and controlling critical environmental conditions such as pH, temperature, dissolved oxygen, and aeration can be done with process instrumentation.
Cleaning and sterilization systems are in place.
It has a harvest system for in-process sampling.
The log10 of a number can be found by writing the number Very large and very small numbers in standard exponential notation.
The log10 is difficult to work with if the coefficients are exactly 1.
It's more convenient to say the same thing as the exponent.
The bers are as a power of 10.
The logarithm function on a positive or negative can be used if the coefficients are not 1, as is often the case.
Follow two steps to change a number.
Microbiologists use logs for calculating pH levels and graphing the coefficients so there is only one growth of population in culture.
The population increases as a cell divides.
The coefficients is 3.2.
If one cell divides into two, you have to count the number of times the number of places you moved the decimal point.
The cell divided if you moved it to the left.
You moved the decimal point seven places to the right in the example.
This would result in a small number if 5 cel s were allowed to divide 9 times.
To calculate the number of generations a culture has undergone, cell num 4,650,000,000 is used.
The on 10 is the number of numbers written in exponential notation.
The log of 2 is used when one cell splits into two.
Microbiologists use exponential notation.
The number of organisms in a population can be described with the use of exponential notation.
Such numbers can be very large.
There are 14 generations in a solution that include media components, disinfectory, antibiotics, and 5 hours of tants.
The calculation can be used to determine the effect of a new carry out.
The growth was stopped by the preservative.
