Concept explainers
To determine: The minerals and nutrients present in the sulfur hot spring that is required in the agar for the maximum growth of micro-organisms.
Introduction: Hot springs are also known as thermal springs. In certain places, the groundwater pools on the ground and such places are called springs. In hot springs, the groundwater gets heated by the energy produced by the Earth. Sulfur hot springs are natural hot springs that contain sulfur.
Explanation of Solution
The minerals and nutrients present in the sulfur hot spring that is required for the maximum microbial growth in the agar include thiosulfate, sulfur-containing amino acids such as cysteine, and ions such as calcium, magnesium, potassium, and sodium. The micro-organisms present in sulfur-rich hot springs use sulfur substances as their energy source.
