DOWNLOAD EBOOK →Growth of microorganisms in water-contaminated, kerosene-type fuels is a widespread problem in aviation. One approach to the solution of this problem is the introduction into fuel of a chemical additive which could stop or retard growth of microbes. Evaluation of the effectiveness of such an additive was conducted in the laboratory under conditions which approximated field operations. Organisms of known identity and isolates from contaminated fuel, when cultured in aqueous nutrient media, responded vairably to the additive; however, most fungi and bacteria were severely inhibited by 1,000-5,000 ppm. In simulated fuel cells containing turbine fuel and an aqueous solution of inorganic salts, all fungi were killed within four days at 270 ppm additive. The effect on bacteria in this system was negligible, an observation supported by a three-month field test in a Convair 880 aircraft where 270 ppm in fuel caused an almost complete disappearance of fungi with little effect on bacteria. Tests also showed that while microbes remain viable in dry fuel, they require a discrete water phase for multiplication. (Author).

DOWNLOAD EBOOK →The Army has three fuel biocides qualified under specification MIL-S- 53021. The military's aviation kerosene, JP-8, also contains an icing inhibitor additive that has some biocidal activity. The relative effectiveness and compatibility of these additives have never been investigated. This study was conducted to evaluate the efficacy of the individual biocides as well as the possible interactions (either synergistic or antagonistic) between these biocides and the icing inhibitor additive. Each of the qualified biocides was evaluated using standard microbiological techniques to determine additive efficacy and compatibility with other fuel additives. The relative effectiveness of the qualified additives was determined. The interactions of the biocides with the icing inhibitor additive in JP-8 were also investigated.

DOWNLOAD EBOOK →My professional interest in antimicrobial agents and contamination control goes back 50 years to my tour as a microbiologist in a field hospital in Europe during World War II. With no experience and relying solely on a military handbook, I prepared thermometer trays with jars of blue bichloride of mercury and pink isopropyl alcohol. A preliminary typhoid diagnosis of one of our cooks resulted in the need for lab testing. His stool specimen and its subsequent disposal was my problem. My handbook said bum it. So burn it T did, in a five-gallon can with gasoline. Flames shot up almost six feet, and my next mistake was to extinguish them with carbon tetrachloride. This resulted in the production of lethal phosgene gas. The hospital had a near disaster. I could say that at that moment I vowed to write a how-to book so that such stupidities could be avoided. Nevertheless, when I was offered the opportunity to edit this book I thought back on the need for a real, practical treatment of my subject. This book, then, is a practical handbook for technical service personnel and scientists who are not necessarily specialists in microbiology. It provides information on suitable antimicrobial agents appropriate to their particular problem-solving needs and information on the microbial groups contributing to the specific problem, their ecologies, and strategies for controlling their access to the area or material of interest.
