Phylogenetic relationship of phototrophic purple sulfur bacteria according to pufL and pufM genes.
The phylogenetic relationship of purple sulfur bacteria (PSB), of the order Chromatiales (class Gammaproteobacteria), was analyzed based on photosynthetic gene sequences of the pufL and pufM genes, and the results compared to phylogenetic trees and groupings of the 16S rRNA gene. Primers for pufL and pufM genes were constructed and successfully used to amplify the pufLM genes of members of 16 g...
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 کاملDetection of Purple Sulfur Bacteria in Purple and Non-purple Dairy Wastewaters.
The presence of purple bacteria in manure storage lagoons is often associated with reduced odors. In this study, our objectives were to determine the occurrence of purple sulfur bacteria (PSB) in seven dairy wastewater lagoons and to identify possible linkages between wastewater properties and purple blooms. Community DNA was extracted from composited wastewater samples, and a conservative 16S ...
متن کاملBistablity in Fluorescence from a purple non-sulfur bacteria
Bistable optical emission has been observed for photosynthetic purple non-sulfur bacteria Rhodobacter capsulatus SB1003. The microbes respond to UV excitation (at 395nm) in a bifurcating way one branch corresponding to increase and the other corresponding to diminishing fluorescent emission in the range 590-685nm.The switching between such bifurcating branches can be observed when parameters li...
متن کاملModeling the electron transport chain of purple non-sulfur bacteria
Purple non-sulfur bacteria (Rhodospirillaceae) have been extensively employed for studying principles of photosynthetic and respiratory electron transport phosphorylation and for investigating the regulation of gene expression in response to redox signals. Here, we use mathematical modeling to evaluate the steady-state behavior of the electron transport chain (ETC) in these bacteria under diffe...
