Endogenous metabolism may conveniently be defined as the total metabolic reactions which occur within the living cell when it is held in the absence of com- pounds or elements which serve specifically as exogenous substrates.

What is endogenous catabolism?
Endogenous metabolism may be considered to fulfill certain functions in the absence of exogenous substrates. ... The concept that endogenous catabolism furnishes energy of mainte nance by means of which microorganisms maintain their status quo, is at tractive and has been discussed by Lamanna & Mallette (65).
What does endogenous phase refer to?
At endogenous (stationary or equilibrium) phase of growth, the bacterial population has reached the carrying capacity of the biological treatment unit. ... Cellular growth is balanced by cellular death during endogenous phase of growth.
Where does endogenous metabolism occur?
Endogenous metabolism may conveniently be defined as the total metabolic reactions which occur within the living cell when it is held in the absence of com- pounds or elements which serve specifically as exogenous substrates.
What is endogenous protein?
Definition: By the term endogenous protein metabolism is meant the disintegration of those proteins which already exist as components of living cells (tissue proteins). The term exogenous protein metabolism implies the breakdown of food proteins which do not exist as parts of the cell protoplasm.
What does a Chemostat do?
A chemostat (from chemical environment is static) is a bioreactor to which fresh medium is continuously added, while culture liquid containing left over nutrients, metabolic end products and microorganisms are continuously removed at the same rate to keep the culture volume constant.
What is an example of an exogenous infection?
A significant amount of prominent diseases are induced by exogenous bacteria such as gonorrhea, meningitis, tetanus, and syphilis. Pathogenic exogenous bacteria can enter a host via cutaneous transmission, inhalation, and consumption.
What are the 4 stages of bacterial growth?
Bacterial colonies progress through four phases of growth: the lag phase, the log phase, the stationary phase, and the death phase. The generation time, which varies among bacteria, is controlled by many environmental conditions and by the nature of the bacterial species.
How does endogenous infection happen?
In the case of endogenous infections, we become infected with our own bacteria, our own microflora. This might happen if a barrier between sterile and non-sterile tissues is broken, such as with a bowel perforation.
What is endogenous source of infection?
Endogenous infections are caused by an overgrowth of organisms that are normally present in the genital tract. One example of an endogenous infection is bacterial vaginosis. Iatrogenic infections may be introduced into the reproductive tract by medical procedures.
What are exogenous and endogenous sources?
The primary exogenous sources of energy for GIT bacteria are undigested carbohydrates and proteins provided via the host diet. Endogenous energy sources include mucin, bile acids, digestive enzymes, and epithelial cells.
Why is it called endogenous?
Processes caused by forces from within the Earth are endogenous processes. Exo is a prefix meaning "out", and endo is a prefix meaning "in".
What is it called endogenous?
Endogenous is a fancy term for anything that originates internally. You're most likely to see the word endogenous when you're dealing with biology, but it can mean "coming from within" in other senses too. Use it for anything that originates inside a system.
What are endogenous chemicals?
"Endogenous" means "produced inside an organism or cell."1 An endogenous substance, therefore, is a substance that originates within the body of a living organism. ... Endogenous is the opposite of exogenous, which means originating outside a living organism.
What is chemostat and turbidostat?
A chemostat has a fixed volume and flow rate, and thus a fixed dilution rate. A turbidostat dynamically adjusts the flow rate (and therefore the dilution rate) to make the turbidity constant. At steady state, operation of both the chemostat and turbidostat are identical.
Who devised the chemostat?
The method of continuous culturing using a chemostat was independently described by Monod3 and Novick & Szilard4 in 1950. As originally conceived, cells are grown in a fixed volume of media that is continually diluted by addition of new media and simultaneous removal of old media and cells (Figure 1).
What is chemostat in microbiology?
A chemostat is defined as a steady-state bioprocess, where a microbial culture is continuously supplied with nutrients at a fixed rate and concomitantly harvested to keep the culture volume constant.
