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.
