Role of lipids in bacterial radioresistance
Creators
Description
The radioresistance of three bacterial isolates was determined. S. aureus was the most sensitive one (D10 value 0.14 KGy), B. coagulans was moderate resistant (D10 value 3.3 KGy) and the most resistant one was B.megaterium (D10 value 3.7 KGy). Total lipids and lipid patterns of these bacteria were determined and the role of lipids in radioresistance was investigated. Least amount of total lipids was detected in the most sensitive organism (S. aureus). The increase in the bacterial content of total lipids was concomitant with high degrees of radioresistance. The most resistant organism (B. megaterium was characterized by high content of methyl esters of fatty acids, phosphatidylcholine and phosphatidylethanolamine, followed by appreciable amounts in the moderate resistant (B. coagulans) and the least amounts were detected in the most sensitive organism (S.aureus).6 fig., 3 tab
