Bacteria perform many important ecosystem services in the soil including improved soil structure and soil aggregation, recycling of soil nutrients, and water recycling. Soil bacteria form microaggregates in the soil by binding soil particles together with their secretions.
What are the economic importance of microorganisms in agriculture?
Microorganisms can improve crop nutrition and the ability of crops to resist biotic and abiotic stress. Thus, greater utilisation of microorganisms in agricultural systems has the potential to allow reductions in the use of inorganic fertilisers, water, herbicides and pesticides.
What is the economic importance of bacteria Class 11?
Industrial uses- bacteria like S. lactis and lactobacillus convert milk to lactic acid. Acetobacter aceti converts oxidizing ethyl alcohol to vinegar. Note:Bacteria like Streptococcus lactis or Lactobacillus lactis, Acetobacter aceti have industrial use in dairy processing industries, preservative factories.
