Questions and Answers

What is the primary role of microorganisms in the rhizosphere, and how do they facilitate nutrient uptake in crop plants?

Microorganisms in the rhizosphere help crop plants' uptake of nutrients by facilitating enzymatic activities, fixing nitrogen, and modifying proteins.

In food fermentation, how do microbial enzymes contribute to the conversion of sugars and modification of proteins?

Microbial enzymes catalyze biochemical reactions, breaking down complex molecules into simpler compounds, and modifying proteins to create desired food products.

What are the factors that can affect enzyme activity, and how can enzymes be stabilized to maintain their function?

Enzyme activity can be affected by temperature, pH, moisture content, ionic strength, and substrate and inhibitor concentrations. Enzymes can be stabilized by adding substrates or solvents at low concentrations.
