Question

Identify the bacteria which spoil cooked food?
(a)Rhizobium
(b)Yeast
(c)Clostridium
(d)Lactobacillus

Answer 1

Hint Bacteria is a prokaryotic microorganism that is few micrometers in length and consists of numerous shapes that range from spherical to spiral. It is a gram-positive bacteria that cause certain diseases like tetanus, diarrhea, etc.

Complete answer:
The bacteria which spoil the cooked food is clostridium. It spoils food which causes food poisoning and is faster in warmer weather so that the food can spoil more quickly and possibly cause severe illnesses. Clostridium constitutes 250 species and is responsible for several diseases in human beings. It is a gram-positive bacteria that includes several human pathogens and causative agents. The biosynthesis of nitrogen-containing organic compounds is done by fixing inorganic nitrogen compounds. microorganisms carry out nitrogen fixation in soil and have symbiotic relationships with plant groups including legumes. It uses lignocellulosic waste which generates ethanol and makes it possible for the candidate to use it in the production of ethanol fuel. It requires no Oxygen and is thermophilic which reduces cooling cost. It is used in the production of acetone and biobutanol from starch for the production of smokeless gunpowder known as cordite. It produces a diluted form in the drug Botox which is a potentially lethal neurotoxin and is carefully injected to nerves in the face that prevents the movement of expressive muscles of the fore had to delay the wrinkling effect of aging.

Additional information:
Rhizobium: It is a diazotrophic bacteria which helps in the fixation of nitrogen in the root nodules of legumes. deer found in the soils and is a group of soil bacteria that produces nodules in the legume and fixes nitrogen gas from the atmosphere which turns into a useful form of nitrogen. The nodules break down and release the rhizobium back into the soil when the legume dies and live individually or reinfect a new legume host.
Yeast: It is a eukaryotic single-celled microorganism that originated millions of years ago and constitutes one percent of all fungal species. They have enabled it to develop multicellular characteristics by the formation of strings that are connected by budding cells which are known as pseudohyphae or false hyphae.
Lactobacillus: It is a gram-positive and rod-shaped bacteria that is non-spore-forming and is a major part of the lactic acid bacteria group which converts sugars to lactic acid. It is a component of the microbiota which are present at several body sites which includes the urinary system, genital system, and digestive system.

So, the correct answer is 'Clostridium'.

Note: Bacteria are the microscopic organisms that get their energy through the organic carbon and are present on planets for more than 3.5 billion years ago and are the oldest life form on the earth. They can tolerate any climatic conditions and lack The structures of eukaryotic cells.
