Tracing Air-Borne Infection by a New Technique—The Detection of Beer Cocci

The Genera of Lactic Acid Bacteria

“…Green and Gray (1949) isolated pediococci from the air of one brewery using an electrostatic sampler.…”

Progress in Brewing Science and Technology

“…The series of articles by Shimwell (168) should be cited. Reference might also be made to a study of the possibility of airborne contamination in the brewery (69) and to the development of a differential procedure for determining bacteria in the presence of large numbers of yeast cells (70,71). Some papers have appeared dealing with the evaluation of malt for brewing purposes (22,48,76,96), and advances have been made in the knowledge of the structure of hop resins (84,35,145,146,189) and in their separation by chromatographic procedures (51,52,147).…”

“…Beginning with a paper in 1936 (54) on the simultaneous determination of carbon dioxide and air in beer, a series of papers has been published by the authors' laboratories dealing with various aspects of measuring and controlling oxidation in beer (55,63,64,66,67,150,194,200). References 55,58,69,62,64,[66][67][68]150,172,174,192,194,200, together with other papers on the general subject of beer stability, have been collected in book form under the title "Bottle Beer Quality. A 10-Year Research Record at Wallerstein Laboratories," published in 1948.…”
