Exalted Level of Nitrogen Metabolism In the Presence of Sodium Sulphide in Nostocellipososporum under Thermal Stress

It is well-recognized that thermophilic cyanobacteria flourish in sulfur-rich thermal springs. Mesophilic cyanobacteria are available at temperatures ranging from 28 to 37°C. This study sought to determine if mesophilic cyanobacteria can also grow at elevated temperatures in the presence of sulphide, and if yes ,then what role sulfide would have in reducing high temperature stress in mesophilic cyanobacterial organisms. The prolifecation of Nostoc ellipososporum, a mesophilic cyanobacterium, was examined at its optimal temperature, both in the presence and absence of sulphide under thermal stress. During the current investigation, nitrate uptake was seen to slow down under temperature stress, but when sulphide was added to the cultures, nitrate uptake increased. This demonstrates that increased levels of nitrogen metabolism in the presence of sulphide contributed to the survival of the test organism under temperature stress.
