Members of the genus LactobacilZus were examined for their ability to synthesize extracellular polysaccharide from sucrose. Strains physiologically similar to L. pastorianus synthesized a glucan. Other strains liberated a complex polysaccharide which contained mannose and glucose. Variants of the glucan-producing strains occurred spontaneously and these(More)
Experiments on continuous culture of rumen contents were undertaken in the hope that a more normal fermentation could be maintained by this procedure than has been possible by batch culture. In the normal rumen fermentation, end products are removed by flow of ingesta down the digestive tract as well as by absorption through the rumen wall. New substrate is(More)
Dunican, L. K. (Cornell University, Ithaca, New York), and H. W. Seeley, Jr. Temperature-sensitive dextransucrase synthesis by a lactobacillus. J. Bacteriol. 86:1079-1083. 1963.-Dextran synthesis was found to be temperature-dependent in Lactobacillus strain RWM-13. Dextran was not formed above 37 C, although growth of cells occurred up to 42 C.(More)
The involvement of epiphytic microorganisms in nitrogen fixation was investigated in a shallow freshwater pond near Ithaca, N.Y. The acetylene reduction technique was used to follow diel and seasonal cycles of nitrogen fixation by epiphytes of Myriophyllum spicatum. Acetylene-reducing activity was maximal between noon and 6 p.m., but substantial levels of(More)
CryENGINE 2 is the most recent version of Crytek’s multiplatform game development middleware, which first came to public notice when it was used in their initial awardwinning title, Far Cry for the PC. It represents the fruits of three additional years of research and development effort since the release of CryENGINE 1 – research that is creating the most(More)

Bacteriol. 82:85-93. 1961.-Three nutritional types of Streptococcus bovis were encountered. Minimal media for their growth are described. Transferable growth in defined media was always accompanied(More)
The genus Pediococcus has long been associated with a type of spoilage of beer called "sarcma sickness" which is characterized by turbidity, a low pH, and by a characteristic "sarcina odor". The odor has been shown to be due to the production of diacetyl by the organism (Shimwell and Kirkpatrick, 1939). Certain strains also have been shown to cause a(More)
