Investigate the factors that affect the rate of respiration in yeast

Among the identified species, some require oxygen to perform cellular breathing whereas others can even sustain in environments deprived of oxygen as they have the ability to perform anaerobic cellular respiration. Yeast derives its energy requirements from organic compounds, which are most likely to be sugar based.

An investigation of the factors that affect the rate of respiration in Yeast.

Due to this phenomenon, these organisms do not depend on sun light for its energy requirements and is often isolated naturally from sugar rich mediums. Among many factors that affect the growth of yeast, some are manipulative through various mechanisms.

  • Sugar concentration As described earlier, yeasts require organic compounds such as sugar derivatives to obtain energy and therefore its concentration in the culture medium or in the environment will affect the rate of its growth;
  • Yeast derives its energy requirements from organic compounds, which are most likely to be sugar based;
  • Yeast derives its energy requirements from organic compounds, which are most likely to be sugar based;
  • Due to this phenomenon, these organisms do not depend on sun light for its energy requirements and is often isolated naturally from sugar rich mediums;
  • Minerals Minerals such as magnesium, potassium and several other trace elements are essential for yeast growth and therefore should encourage growth when provided externally.

However, not all yeasts thrive on same environmental states and therefore needs individualized attention according to the type of species when cultured in the lab. Factors affecting yeast growth: Following is a brief description of factors controlling how yeasts grow.

  1. Oxygen As described earlier, although anaerobic respiration is possible, many yeast strains will require oxygen enriched medium for its metabolic functions. However, further research is required to link type of strain and its growth to understand its correlation better.
  2. Phosphorus When considering its part as an element in the nucleic acids and phospholipids, provision of phosphorus is important for effective yeast growth. Oxygen As described earlier, although anaerobic respiration is possible, many yeast strains will require oxygen enriched medium for its metabolic functions.
  3. When it comes to culture medium, scientists use the same characteristic in organic acids for its use as an effective culture medium.
  4. Factors affecting yeast growth.
  5. Thus, yeast extracts or foods derived from yeasts are more likely to be acidic. Following is a brief description of factors controlling how yeasts grow.

Temperature Yeasts can tolerate extreme temperatures although it may lose its viability with time. Some yeast live in freezing conditions but many will grow in normal environmental temperatures existing in many places.

Factors that Affect Yeast Growth

Therefore, refrigeration or deep freezing may not be a full proof method to prevent yeast formation. Thus, yeast extracts or foods derived from yeasts are more likely to be acidic. When it comes to culture medium, scientists use the same characteristic in organic acids for its use as an effective culture medium.

Sugar concentration As described earlier, yeasts require organic compounds such as sugar derivatives to obtain energy and therefore its concentration in the culture medium or in the environment will affect the rate of its growth. Type of strain Certain strains or species of yeasts will grow rapidly whereas some may be relatively slow. However, further research is required to link type of strain and its growth to understand its correlation better.

Oxygen As described earlier, although anaerobic respiration is possible, many yeast strains will require oxygen enriched medium for its metabolic functions. Thus, when yeasts grow in a lab, they receive an aerobic environment for effective growth.

Minerals Minerals such as magnesium, potassium and several other trace elements are essential for yeast growth and therefore should encourage growth when provided externally. Phosphorus When considering its part as an element in the nucleic acids and phospholipids, provision of phosphorus is important for effective yeast growth. Sulphur It is an essential element of certain amino acids and when added to a culture medium, it will encourage yeast growth.

Growth factors Scientists have learn that, yeasts require certain vitamins, purines, pyrimidines, amino acids, fatty acids…etc for catalyzing the biosynthesis although they do not act as energy sources for yeasts. Apart from the above, there can be many other factors contributing to the growth of yeast and require further research to determine how extensively they affect in their growth.
