Project Details

Description

Very often, sulphate rich aquatic environments display an intense production of hydrogen sulphide which can accumulate reaching concentrations potentially harmful for most living organisms. Under favourable conditions hydrogen sulphide is oxidized by sulphur bacteria. These bacteria, can develop rapidly giving rise to the formation of laminated structures in the surface of sediments (microbialmats) or to bacterial plates in stratified water columns.
The main purpose of this project is the assessment of the role of sulphur oxidizing bacteria in natural environments, trying to cover four main items: 1) Determination of the abundance of sulphur oxidizers in a number of different environments.2) Quantification of their sulphide oxidizing activity 3) Assessment of their contribution to the primary production of the environments where they live 4) Analysis of the environmental conditions controlling their growth and activity in nature
The information obtained along these lines will allow for a better understanding of the role played by these organisms in the detoxification of hydrogen sulphide, laying at the same time the basis for the development of management strategies in environments affected by the presence of this compound
