With Biochemist David Gutnick, Rosenberg isolated a genus of bacteria called arthrobacter, which feast on crude oil, and then developed a particularly fast-multiplying new strain, which they named "RAG-1."* Bred in salt water enriched with phosphorus and nitrogen compounds, the strain gobbles up the paraffin (waxy) content of crude oil, leaving only small droplets of dewaxed oil that break down quickly in nature and become harmless carbon dioxide and water...
...tons of sea water, they poured 55 lbs. of nitrogen-containing urea and 2.2 lbs. of potassium phosphates into each. Shipboard compressors were used to bubble air into the tanks through a perforated hose, thus turning them into ideal "bacterial fermenters," says Rosenberg. Then a flaskful of RAG1 bacteria was poured into one tank. Six and a half days later, the tanker discharged its ballast. The unbugged tank emitted an ugly black slick. But there was hardly any slick from the other tank; the bacteria had multiplied and taken the polluting elements...
...knew nothing about the immune system, but he had recognized that milkmaids who frequently came in contact with cows suffering from cowpox seldom contracted smallpox. Scientists began to suspect that the body had a mechanism for identifying and combatting disease agents only after Louis Pasteur discovered the existence of bacteria and in the 1850s propounded the germ theory of disease...
...have borrowed a leaf from Coley's book and have been trying, with some success, to awaken sleeping immune systems to combat cancer. The techniques of this approach vary widely. Some doctors still use Coley's bacterial-toxin formula; others inject vaccine made from killed mumps virus and diphtheria bacteria. Many, however, prefer a live-bacteria tuberculosis vaccine called BCG (for Bacillus Calmette-Guerin, after the Frenchmen who developed...
...Gallos' impact on American wine making has been enormous. They were the nation's first wine makers to hire research chemists. Years ago they abandoned wooden fermenting casks for stainless-steel tanks, and because wood casks can breed unwanted bacteria, most of the domestic industry has followed. The Gallos were the first to automate their wineries by, among other things, computerizing the blending process. They also pioneered in pop wines-the sweet and occasionally effervescent drinks that are washing over the country. Last year, producing six of the dozens of entries on the market, Gallo accounted...
