Formation of Auxin in Yeast Cultures by True W. Robinson And
نویسنده
چکیده
The production of auxin by yeast ceils resembles the formation observed in other organisms such as Rhizopus and Rkizobiura (Thimann, 1939) I which "release" auxins into their culture medium. Thus, we have found far more auxin in the growth medium of yeast than KSgl and Kostermans 2 extracted from the cells. The amounts of auxin in the growth medium were found to vary considerably with the age of the culture, the rate of growth of the cells, and both the initial and final composition of the growth medium.

Formation 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 ...

This study was intended to use the sourdough LAB containing specific starter cultures for Barbari bread production and reduction of its staling. For sourdough preparation, fresh microbial cells were collected by centrifugation from LAB cultures. Then 1.5% of flour (w/w) from these washed cells with the same amounts of wheat flour and tap water and 0.25% (w/w) active dry yeast extract, containin...

In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...
متن کاملPseudohyphae formation in Candida glabrata due to CO2 exposure
Background and Purpose: Formation of pseudohyphae is considered a virulence factor in Candida species. Generally, Candida glabrata grows as budding yeast cells; however, reports illustrated that C. glabrata could form pseudohyphal cells in response to some stimuli. In this study, we provided insight into the ability of C. glabrata in forming pseudohyphal cells under different levels of carbon d...
