Question

Although macroscopic observations of microbial growth can provide much valuable information, microbiologists often follow such observations with microscopic analysis. What information might one learn by using a microscope? What are some additional factors to test in trying to identify an unknown microbe obtained from the environment?Was any growth observed on the control plate? What would growth on the control plate indicate about the aseptic technique used?

Answer 1

The person can see microorganisms such bacteria and viruses and their shape and structure composition.

Yes, growth was observed on the control plate.

The aseptic technique indicates that the model was an appropriate method to prevent contamination of the control plate.

Step-by-step explanation:

Micrscope is an instrument which is used to see small organisms which cannot be seen through naked eyes. With the passage of time, micobes such as bacteria multiply through binary fission. Aseptic technique allows the prevention of pathogens to the tools used for the observation.

Answer 2

Step-by-step explanation:

As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.

With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.

When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.

No growth was observed on the control plate.

The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.
