प्रश्न

In industries microbial enzymes are used over chemical enzymes.

थोडक्यात उत्तर

उत्तर

Microbial enzymes are used instead of chemical enzymes in industries because:

  1. Corrosion is a common problem in chemical industries. Using anticorrosive instruments increases the production cost. However, while using microbial enzymes costly anti-corrosive instruments are not required.
  2. Microbial enzymes are active at low temperature, pH and pressure. Thus, they save energy.
  3. Enzymes carry out specific processes due to which unnecessary byproducts are not formed. Thus, expenses on purification are minimized.
  4. In microbial enzymatic reactions, elimination and decomposition of waste material is avoided and enzymes can be reused. Thus, microbial enzymes are eco-friendly.

Read the following paragraph and write the answers to the questions asked.

Sulphuric acid is present in the acid rain and materials coming out of mines. You know that erosion of metals present in statues, bridges and buildings occurs due to it. Sulphuric acid is a source of energy for some species of bacteria like Acidiphilium spp. and Acidithiobacillus ferrooxidans. Hence, these bacteria can control the soil pollution occurring due to acid rain. Water soluble salts of uranium are present in the wastes produced during electroplating and in effluent released in the environment from the atomic energy plant. Geobacter convert these salts of uranium into insoluble salts and thereby prevent those salts from mixing with groundwater sources.

  1. What causes metal erosion in statues, bridges and buildings?
  2. Sulphuric acid is the source of energy for which bacteria?
  3. What kind of pollution do these bacteria control?
  4. What are the water soluble salts in atomic energy plants and in the process of electroplating?
  5. Which bacteria prevent these salts from mixing with ground water by converting them Into insoluble salts?
