250 g of Methylophilus methylotrophus can obtain as much as _______________ of proteins as compared to 250 kg cow that produces only 200 g of proteins.
1 250 tonnes
2 25 tonnes
3 2.5 tonnes
4 12 tonnes
Explanation:
Methylophilus methylotrophus is a bacterium with a generation time of only 2 hours. The rapid growth rate of the bacterium supports a high rate of biomass production to give 25 tonnes of proteins from 250 g of the bacteria.

Select the incorrect match from the given examples of single cell protein microbes.
1 Bacteria: Methanomonas, Pseudomonas, Bacillus
2 Yeast: Candida utilis, S. cereviseae, Pichia pastoris
3 Fungi: Fusarium, Aspergillus, Penicillium
4 Algae: Spirullina, Chiarella, Hydrogenomonas
Explanation:
Hydrogenomonas is a rod-shaped soil bacteria and contains high levels of proteins rich in essential amino acids. It is one of the bacterial sources of single cell proteins.

Assertion: Microbes have higher growth rates and produce more biomass in less time. Reason: Some microbial species are rich sources of essential amino acids.
1 Both assertion and reason are true but reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
Generation time for microbes is very less which in turn allows their rapid multiplication. Some microbes are used as single cell proteins as they are rich sources of proteins with the desirable composition of amino acids.

Assertion: Algae are autotrophs and produce organic matter by the process of photosynthesis. Reason: Spirulina and Scenedesmus are the most commonly used bacterial sources of single cell proteins.
1 Both assertion and reason are true but reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
Algae are photosynthetic organisms and produce organic nutrients by fixing CO2 in the presence of sunlight. Spirulina and Scenedesmus are the most commonly used algal sources of single cell proteins.
