Which non-toxic, fast growing cyanobacterium is cultivated in tanks as a protein-rich animal feed?

  2. Spirulina

  3. Nostoc

  4. Oscillatoria

B Correct answer
Explanation
Spirulina represents a biomass of cyanobacteria (blue-green algae) that can be consumed by humans and other animals. The two species are Arthrospira platensis and A. maxima. Cultivated worldwide, Arthrospira is used as a dietary supplement or whole food. It is also used as a feed supplement in the aquaculture, aquarium, and poultry industries. Spirulina was found in abundance at Lake Texcoco by French researchers in the 1960s, but no reference to its use was made by the Aztecs as a daily food source after the 16th century, probably due to the draining of the surrounding lakes for agriculture and urban development. As an ecologically sound, nutrient-rich, dietary supplement, spirulina is being investigated to address food security and malnutrition, and as dietary support in long-term space flight or Mars missions. Its interest for food security is for lower land and water needs to produce protein and energy than required for livestock as meat sources.
So the correct option is 'spirulina'.

C Correct answer
Explanation

Chlorella is a type of algae that grows in fresh water. The whole plant is used to make nutritional supplements and medicine. It is processed and made into tablets and liquid extracts. These extracts contain "chlorella growth factor," which is described as a water-soluble extract of chlorella containing chemicals including amino acids, peptides, proteins, vitamins, sugars, and nucleic acids. As a medicine, chlorella is used for preventing cancer, reducing radiation treatment side effects, stimulating the immune system, improving response to flu vaccine, increasing white blood cell counts (especially in people with HIV infection or cancer), preventing colds, protecting the body against toxic metals such as lead and mercury, and slowing the aging process.
Chlorella is also used to increase good bacteria in the intestine in order to improve digestion; and to help treat ulcers, colitis, Crohn's disease, and diverticulosis.
Some people also use chlorella for the prevention of stress-related ulcers; treatment of constipation, bad breath, and hypertension; as an antioxidant; to reduce cholesterol; to increase energy; to detoxify the body; and as a source of magnesium to promote mental health, relieve premenstrual syndrome (PMS), and reduce asthma attacks. It is also used for fibromyalgia.
Chlorella is applied to the skin for treating skin ulcers, rashes caused by radiation treatment, and a sexually transmitted disease called trichomoniasis. Chlorella is a good source of protein, fats, carbohydrates, fiber, chlorophyll, vitamins, and minerals. The cell wall of chlorella must be broken down before people can digest it.

Spirulina is a cyanobacterium that can be consumed by humans and other animals as a protein supplement.
