Q1. What is the process of fermentation?
Ans. 
Fermentation is a metabolic process converting sugars into acids, gases, or alcohol using microorganisms under anaerobic conditions.
• Involves microorganisms like yeast and bacteria.

• Occurs in anaerobic conditions (absence of oxygen).

• Commonly used in food production, e.g., bread, yogurt, and beer.

• Yeast ferments sugars to produce alcohol and carbon dioxide in brewing.

• Lactic acid bacteria ferment lactose to produce yogurt.

Q2. What are the requirements for fermentation?
Ans. 
Fermentation requires specific conditions, including microorganisms, substrates, temperature, and anaerobic environments.
• Microorganisms: Yeasts (e.g., Saccharomyces cerevisiae) or bacteria (e.g., Lactobacillus) are essential for fermentation.

• Substrates: Sugars or carbohydrates (e.g., glucose, maltose) serve as the primary energy source for fermentation.

• Temperature: Optimal temperatures (usually between 20-30°C) are nec...read more

Q3. What are the key factors that influence the fermentation process?
Ans. 
Fermentation is influenced by factors like temperature, pH, oxygen levels, and nutrient availability, affecting microbial activity.
• Temperature: Optimal ranges (e.g., 30-37°C for yeast fermentation) enhance microbial activity.

• pH Levels: Most fermentations prefer a pH of 4-6; extreme pH can inhibit growth.

• Oxygen Availability: Anaerobic conditions are crucial for processes like alcohol fermentation.

• Nutrient Availability: ...read more

Q3. What is crystallization?
Ans. 
Crystallization is the process of forming solid crystals from a homogeneous solution or melt.
• Occurs when a solute concentration exceeds its solubility limit.

• Can be induced by cooling a solution or evaporating the solvent.

• Examples include sugar crystallizing from syrup and salt from seawater.

• Used in purifying substances, such as in the production of pharmaceuticals.
