Biofiltration of reduced sulphur compounds and community analysis of sulphur-oxidizing bacteria.
The present work aims to use a two-stage biotrickling filters for simultaneous treatment of hydrogen sulphide (H(2)S), methyl mercaptan (MM), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). The first biofilter was inoculated with Acidithiobacillus thiooxidans (BAT) and the second one with Thiobacillus thioparus (BTT). For separate feeds of reduced sulphur compounds (RSC), the eliminatio...
متن کاملBiotechnological Applications of Purple Non Sulphur Phototrophic Bacteria: a Minireview
Bacteria play in vital role in the production of variety of products, including certain plastics and enzymes used in detergents, textiles and pharmaceutical industries. Production of chemicals using bacteria and other microorganisms is not only economical sustainable but also ecofriendly. Modern biotechnology entails the use of cell fusion, bioinformatics, genetic engineering, structure based m...
متن کاملSulphur Oxidizing Bacteria and Pulse Nutrition - A Review
Sulphur oxidizers are involved in oxidation of elemental sulphur to plant available sulphate. Sulphur is the key element for higher pulse production and plays an important role in the formation of proteins, vitamins and enzymes. Sulphur is a constituent of the essential amino acids cystine, cysteine and methionine. In the recent years the importance of sulphur in pulse nutrition has been well r...
متن کاملAnalysis of Sulphur-Oxidizing Bacteria Attack on Concrete Based On Waste Materials
Concrete durability as an important engineering property of concrete, determining the service life of concrete structures very significantly, can be threatened and even lost due to the interactions of concrete with external environment. Bio-corrosion process caused by presence and activities of microorganisms producing sulphuric acid is a special type of sulphate deterioration of concrete mater...
متن کاملDynamics of anoxygenic photosynthesis in an experimental green sulphur bacteria biofilm.
The dynamics of sulphide oxidation in an experimental biofilm of the green sulphur bacterium, Prosthecochloris aestuarii, were studied using a newly developed light-dark cycling procedure. The biofilm was grown for 6 weeks in a benthic gradient chamber, in which gradients of light, sulphide and oxygen were imposed experimentally. The H2S concentrations and pH were measured with microsensors as ...
