Questions & Answers

Q: What are some examples of organic acids produced by microbes?

Some examples of organic acids produced by microbes are lactic acid, acetic acid, botanic acid, and citric acid. These acids find applications in processes like curdling of milk and food preservation.

Q: How do enzymes produced by microbes contribute to digestion and absorption?

Enzymes like lipase and protease help break down complex lipids and proteins into simpler forms during digestion. This breakdown is necessary for the body to absorb these essential nutrients.

Q: What is the significance of streptokinase enzyme produced by streptococcus bacteria?

Streptokinase is important in thrombolysis, which is the dissolution of blood clots. This enzyme is used in medication to effectively dissolve severe blood clots.

Q: How does Saccharomyces cerevisiae contribute to alcohol production?

Saccharomyces cerevisiae, a type of yeast, performs ethanol fermentation in the absence of oxygen, converting sugars like glucose, fructose, and lactose into ethanol and carbon dioxide. This process is responsible for alcohol production.

Summary & Key Takeaways

  • Microbes produce important chemicals such as organic acids, enzymes, and alcohol, which have various applications in different fields.

  • Examples of organic acids produced by microbes include lactic acid, acetic acid, botanic acid, and citric acid.

  • Enzymes produced by microbes, like streptokinase, lipase, protease, and pectinase, help in processes such as thrombolysis, fat hydrolysis, protein breakdown, and plant cell wall digestion.

  • Yeast, specifically Saccharomyces cerevisiae, plays a crucial role in alcohol production through ethanol fermentation.
