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. Logarithmically growing cells transferred from 30 ...

In this study, we aimed to determine the in vitro activity of Leuconostoc mesenteroides var. isolatedfrom sugar-industry effluents produce a dextran bioflocculant from sucrose as low-cost substrate.L. strains present residual cane juice sugar factory were isolated and biochemicallyidentified using Mayeux, Sandine, Elliker agar (MSE) selective medium. The strain number 3 (LM03) wasbiochemically ...

The production of slime by microorganisms in the sugar cane juice of sugar mills has been primarily attributed to Leuconostoc mesenteroides (McCleskey, Faville, and Barnett, J. Bacteriol., 54, 697, 1947). In a study of the epiphytic microflora of sugar cane, Mayeux and Colmer (Sugar J., 23, 28, 1960) reported the presence of many organisms on the growing plant but failed to show the presence of...

Various traditional fermented yak milk and raw milk foods could be considered as an abundant resource for obtaining novel lactic acid bacteria (LAB) with unique properties. Eighty-eight samples of yak milk products were collected from Gansu Province in China. Three hundred and nineteen strains of LAB isolated from these samples were identified by phenotypic methods, 16S rRNA gene sequence analy...

As in the traditional production of cheese in lambskin sacks raw cow's or sheep's milk is mostly used, the purpose of this study is to see how the production affects the microbiological quality of the cheese. To do that, we tested 39 samples of raw cow's and sheep's milk, curd, ripened cheese (15, 30 and 45 days) and lambskin sacks for native microbial population. Two-thirds of the milk, curd a...
