1. What are halophilic, thermoacidophilic and methanogen archaebacteria? 2. What are the main ecological roles of bacteria?Describe the methanogen, thermoacidophile and halophilic archaebacteria with examples?What is the difference between archaebacteria and eubacteria?
A decrease in the extracellular H+ concentration creates difficulties for membrane-linked energetics in bacteria employing H+ as the coupling ion. At high extracellular pH (pHo), H+ ions pumped from the cell by, say, the respiratory chain, are immediately neutralized by the alkaline extracellular...
Several species are found in soil with high salt concentration (some even require nearly 5M NaCl concentration in media to grow). Somehalophilic ActinobacteriaareSalinispora, Dietzia, Williamsia, Marinophilus, etc. Endophytic Actinobacteriaare also widely isolated and studied. Most of them are associat...
Ectoine is found in high concentrations in halophilic microorganisms and confers resistance towards salt and temperature stress. Ectoine was first identified in the microorganism Ectothiorhodospira halochloris, but has since been found in a wide range of Gram-negative and Gram-positive bacteria. ...
1. What are halophilic, thermoacidophilic and methanogen archaebacteria? 2. What are the main ecological roles of bacteria? What are the properties of living organisms? What conditions determine whether Euglena feeds in a phototrophic or heterotrophic manner? What is Biosphere and its types? In wh...
microbial growth is suppressed. Microorganisms likely to be found in pharmaceutical drug products will not grow at Aw less than 0.75, furthermore the compendial methods found in USP <61> and <62> will not detect halophilic bacteria, osmophilic yeast, and xerop...
The color comes from halophilic archaebacteria and minerals. By anon47024 — On Sep 30, 2009 anon35523, I'm in Delhi and looking for the pink salt. Can you please let me know which bazaar I can find it at? Thanks! --G By anon39843 — On Aug 04, 2009 I've seen it ...
so it was named HCLase. Research on basic enzymatic properties shows that HCLase is different from reported glycosaminoglycan degrading enzymes in that it has halophilic properties, which is related to its origin from marine bacteria, and exhibits good temperature and pH stability. Substrate degradatio...
Methanogens are archaebacteria found in animal guts. 8 Eubacteria Conversion of nitrogen into usable forms. Rhizobium is a nitrogen-fixing eubacterium that aids plant growth. 7 Archaebacteria Salt-loving organisms. Halophilic archaebacteria thrive in the Dead Sea's salty environment. 8 Eubacteria ...
