Question

disadvantages of microorganism in the industry

Answer 1

microorganisms have a definite shelf life and they need to be grown on optimum medium for continuous multiplication. they can grow beyond control sometimes and then become difficult to get rid off. it is tedious to separate the organisms from the products as they are very small, more so if the sizes of the microbes and the products are very similar microorganisms are living beings and for no reason at all they can all die or grow abnormally and a new batch of organisms will then have to be procured, getting the same strain would then be difficult a single base difference in genetically modified microbes used to produce proteins for antibiotics etc will form spirulous proteins. even a shift in the reading frame may lead to this. therefore it is better to use tissue culture for these. many of the microbes used in such processes are antibiotic resistant and therefore they need to be heat killed before they can be discarded

Microorganism➫ An organism that can be seen only with microscope & that typically consists of only a single cell.

♦ It can only be viewed through a microscope.

♦ It widespread in nature & are beneficial to life but some can cause serious harm.

♦ It include Bacteria, Protozoans, Algae & Fungi.


➧ Types 0f Microorganism are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵

[1] Bacteria:-

❱ A single-celled organisms that thrive in diverse environments.

[2] Fungi:-

❱ A single-celled or multicellular organism & can be true pathogens.

[3] Viruses:-

❱ A small infectious agent that replicates only inside the living cells of other organisms.

[4] Protozoa:-

❱ Any of a large group of one-celled organisms that live in water or as parasites. 

[5] Algae:-

❱ A type of plant-like living things that can make food from sunlight by photosynthesis.

➧ Advantage 0f Microorganism are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵

❱ They fix gases & breaking down dead plant & animal matter into simpler substances.

❱ They help in production of food materials such as bread, cheese & curd.

❱ They help us digest food & regulate the production of vitamins & nutrients.

❱ They fight against those harmful bacteria which can cause diseases.

❱ They help in preparation of vaccines.

❱ They help in Fermentation.

➧ Disadvantage 0f Microorganism are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵

❱ They cause diseases & infection.

❱ They lowers the immune system of the body which makes path to various bacteria into the body.

❱ Some bacterial infections like Pneumonia can sometimes cause death.

❱ Bacterial infections can breakdown skin & organs.

❱ They can cause severe gastrointestinal infections as a consequence of the ingestion of contaminated food.

➧ To Prevent the Microorganism are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵

❱ Get the appropriate vaccine.

❱ Wash your hands frequently.

❱ Stay home if you are sick (so you do not spread the illness to other people).

❱ Use a tissue or cough & sneeze into your arm, not your hand.

❱ Use single-use tissues.

➧ The conditions / Factors which Microorganism grows:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵

[1] Time:-

❱ A single bacterium can multiply to over two million in just seven hours.

[2] Warmth:-

❱ The danger zone temperatures at which bacteria grow best are between 5ºC and 63ºC.

[3] Food:-

❱ Any other living things, germs need food to grow.

[4] Water:-

❱ Bacteria need moisture to grow.
