Yeast Cultures in Ruminant Nutrition
DENEV, S. A., Tz. PEEVA, P. RADULOVA, P. STANCHEVA, G. STAYKOVA, G. BEEV, P. TODOROVA and S. TCHOBANOVA, 2007. Yeast cultures in ruminant nutrition. Bulg. J. Agric. Sci. 13: 357-374 Interest in the use of fungal direct-fed microbials in ruminant nutrition is considerable. The ban of antibiotic growth promoters in feed for production of animal foods has increased interest in evaluating the effec...
متن کاملInvolution Matrices of Real Quaternions
An involution or anti-involution is a self-inverse linear mapping. In this paper, we will present two real quaternion matrices, one corresponding to a real quaternion involution and one corresponding to a real quaternion anti-involution. Moreover, properties and geometrical meanings of these matrices will be given as reflections in R^3.
متن کاملThe Preservation of Yeast Cultures by Lyophilization.
Since the pioneer work of Rogers (1914) on drying cultures from the frozen state and the wide application of this procedure to bacteria, the lyophil process has been shown to be a successful method for the preservation of yeast cultures in a viable state over extended periods (Elser et al., 1935; Wickerham and Andreasen, 1942; Wickerham and Flickinger, 1946). The fundamental value of this metho...
متن کاملFormation of Auxin in Yeast Cultures
We have found far more auxin in the culture media of bakers' yeast than was obtained by Kögl and Kostermans from the cells themselves. The production of auxin by yeast cells resembles the formation observed in other organisms such as Rhizopus and Rhizobium which also form auxins in their culture media. The auxin yield was found to increase with the concentration of sucrose and to decrease with ...
متن کاملAn emerging issue of mixed yeast cultures.
BACKGROUND Different yeast species have different susceptibilities to commonly prescribed antifungal drugs. Thus, it is important to accurately determine the species of pathogenic yeasts, especially when more than one species are in a specimen. METHODS Clinically significant yeast isolates were collected via the Taiwan Surveillance of Antimicrobial Resistance of Yeasts from July to September ...
