To make sure that they don't turn homosexual and end up trying to reproduce with the other gay microbes.
Compare the original microbes with the microbes in the new culture.
Nitrogen is a major nutrient or macronutrient for microbes as wells as other organisms. Absolutely essential for aminoacids and protein synthersis. Deficiency cause many disease related to protein deficiency and microbes will not able to gro well so that is a reason that we add peptone in culture medium for microbes
If you do open one or more of them, you can contaminate them with microbes. These will most likely not be the ones you are trying to culture. It can give you a false negative.
Microbes are tiny organisms that are found everywhere, including in the soil, air, and human bodies. Studying microbes can provide insights into disease, environmental impact, and biotechnology. Scientists use various techniques to isolate, culture, and study different types of microbes.
Scientists can obtain microbes by collecting samples from various environments such as soil, water, or the human body. These samples are then cultured in a laboratory setting to isolate and study the microbes. Alternatively, scientists may also receive microbial strains from culture collections or other researchers.
If you do open one or more of them, you can contaminate them with microbes. These will most likely not be the ones you are trying to culture. It can give you a false negative.
Alexander flaming discovered microbes
microbes can live anywhere!
sometimes Bactria can kill microbes
Fermentation process microbes.
Cotton is used as plugs for glass wares containing culture medium to allow for gas exchange while preventing contaminants from entering the vessel. The cotton acts as a barrier, allowing oxygen to enter the vessel for aerobic growth while protecting the culture from airborne contaminants.
Basically all the reacitons in living systems are thermodynamic. Some of thems are exergonic which liberate heat energy and some are endergonic which utilize heat energy. Same type of reactions utilize or liberate same amount of heat energy. This energy will be constant for a particular reaction. The amount of heat liberated by same type of reactions in any microbial culture will be directly proportional to the number of microbes. So by finding the amount of heat energy produced or utilized by any microbial culture one can estimate the number of microbes present in that culture. This is the principle behind microbial calorimetry. S.Manu. Lecturer, MVJ College of Engineering, Bangalore. The number of microbes may not be accurate but it will be in the range. It depends on different aciviteis of the microbes and the growth phase of the microbes. They liberate different amonut of heat in different phases. So many correction factors are needed to make out correct number of microbes in a culture.
