AIIMS 2017 Botany Bacterial Activities MCQ Question

The preparation and flowering of tea and tobacco leaves are influenced by Acetobacter aceti, a bacterium that plays a crucial role in the fermentation process, converting ethanol into acetic acid, which is important for the flavor and quality of these crops. Other options are incorrect because Bacillus subtilis and Bacillus megatherium are primarily involved in soil health and nutrient cycling, while Streptococcus lactis is associated with dairy fermentation rather than plant growth. Understanding the specific roles of these microorganisms helps elucidate their impact on agricultural practices and crop quality.
