As described in "A Note About Bacterial Reproduction -- and the "Culture Bias,"" the organism Epulopiscium does not divide by bi
gayaneshka [121]

In liquid media or broth difference between dry and wet will give biomass of the Epulopiscium.

Explanation:

Biomass of bacteria can be measured by dry or wet mass. Bacteria numbers can be counted by spread plate method under the microscope.

In solid media the colonies obtained are diluted and number of cells will be seen by plate count method or on automated cell counter. The number would help calculate biomass

The biomass will be calculated by measuring wet and dry mass. Equipments required will be:

hydraulic gravity convection oven and centrifugation set up.

A cellulose acetate filter membrane is used which is 47 mm in diameter and 0.45 micron of pore size.

The cells  grown settles down due to gravity. They are stirred to evenly spread in the broth and is kept in centrifuge.

The cells obtained after centrifugation will be taken and wet weight is obtained.

To obtain dry weight the cells are placed in oven for 6 hours to 24 hours. The resultant cells are weighed and dry weight obtained.

Biomass will be calculated by subtracting the wet mass to dry mass. This way biomass is obtained in epulopisicuium. Here the cells will be of different size so on centrifugation 2 or more phases of cells can be seen due to gravity change.

what were the historical reasons for the resistance to recognizing airborne transmission during the covid-19 pandemic?
ExtremeBDS [4]

Up until a 1962 demonstration of tuberculosis airborne transmission, airborne transmission of all major respiratory diseases was assumed to be of insignificant or moderate consequence over the following fifty years.

Before COVID-19, only a small number of diseases—those that were blatantly spread to people not in the same room—were generally acknowledged as airborne. This is because the contact/droplet paradigm remained popular.

<h3>What does the term "airborne transmission" mean?</h3>
  • The term "airborne transmission" refers to the propagation of droplet nuclei (aerosols) that retain their infectious properties after being suspended in air for a lengthy period of time and over great distances.
  • Bacteria or viruses that cause airborne infections are most frequently spread by tiny respiratory droplets. When a person with the airborne sickness sneezes, coughs, laughs, or exhales in any other way, these droplets are released.
