...only recently, in deference to La Prensa-led opposition, they had put off the controversial oil deal till July. To place themselves beyond suspicion during the investigation, the three Apra Cabinet ministers resigned, thereby causing the Cabinet to fall. Apra's La Tribuna offered a $3.000 reward for the murderer...
Bacteria found in deep sea mud might soon make oil wells as buggy as vinegar works. Last week Dr. Claude E. ZoBell, of the Scripps Institution of Oceanography, La Jolla, Calif., announced that he was well along on a process to infect exhausted oilsands with these bacteria...
Snuffling underground like fierce micro scopic ferrets, they would chase residual oil toward waiting wells...
...ZoBell has busied himself for years with the microflora of oil strata, including sea-bottom muds where oil is thought to be formed. His original idea was to study how bacteria modify crude oil (TIME, Dec. 17, 1945). But in 1943, he found in sea mud a comma-shaped bacterium which he named (he was only 38 at the time, and feeling in the pink) desulphovibrio halo-hydrocarbonoclasticus. He put it in a test tube filled with material to simulate a limestone oilsand. Four days later, oil bubbled out of the test tube's mouth. A little later...
...sheer multiplication, the bacteria push oil particles off the grains of oilsand. They dissolve limestone, making the formation more porous. They generate carbon dioxide, which pushes oil particles ahead of it by gas pressure. The bacteria also produce a "detergent" (soaplike substance) which makes clinging oil films gather into free globules...
