backgrounds: optimization of microbial compositions and load in live food during the process of bioencapsulation is one of the most important concerns in aquaculture, as it can promote the growth and feeding parameters of fish larvae. objectives: the aim of this study was to determine the growth and feeding performance of persian sturgeon larvae fed with bioencapsulated d. magna with saccharomy...

Having determined the mass of a single cell of brewer yeast Saccharomyces cerevisiae by means of a microcantilever-based biosensor Cantisens CSR-801 (Concentris, Basel, Switzerland), it was found that its dry mass is 47,65 ± 1,05 pg. Found to be crucial in this mass determination was the cell position along the length of the cantilever. Moreover, calculations including cells positions on the ca...

A simple and rapid method of yeast strain characterization based on mitochondrial DNA restriction analysis was applied to the control of wine fermentations conducted by active dry yeast strains. This molecular approach allows us to understand several important aspects of this process, such as the role of the active dry yeast strain and that of the natural Saccharomyces cerevisiae flora during v...

The study was performed in a batch system in order to determine the effects of pH and temperature on growth and glycerol production kinetics of two indigenous wine yeast strains Saccharomyces cerevisiae Kalecik 1 and Narince 3. The highest values of dry mass and specific growth rate were obtained at pH 4.00 for both of the strains. Maximum specific glycerol production rates were obtained at pH ...

In unicellular organisms like yeast, mating with the right partner is critical to future fitness because each individual can only mate once. Because cell size is important for viability, mating with a partner of the right size could be a significant advantage. To investigate this idea, we manipulated the size of unmated yeast cells and showed that their viability depended on environmental condi...

Cleavage and polyadenylation of eukaryotic mRNA requires efficiency and positioning elements in the 3'-untranslated region (3'-UTR) of the mRNA. Specific point mutations were introduced into the yeast GCN4 3'-UTR to detect sequence motifs which are involved in the positioning of the poly(A) site. 3'-End proces-sing activities of different GCN4 3'-UTR alleles were measured in an in vivo test sys...

There is significant interest in inferring the structure of subcellular networks of interaction. Here we consider supervised interactive network inference in which a reference set of known network links and nonlinks is used to train a classifier for predicting new links. Many types of data are relevant to inferring functional links between genes, motivating the use of data integration. We use p...

TORC1-dependent phosphorylation of Saccharomyces cerevisiae Sch9 was dramatically reduced upon exposure to a protonophore or in respiration-incompetent ρ(0) cells but not in respiration-incompetent pet mutants, providing important insight into the molecular mechanisms governing interorganellar signaling in general and retrograde signaling in particular.

The present study was aimed to use spent wash as a substitute for expensive commercial media for Rhizobial cultures. Growth of Rhizobium strains at different concentrations of spent wash was observed and found maximum at 50% spent wash. Bacteria were grown on 50% spent wash which produced remarkable results and competed with standard media like tryptone yeast extract, Rhizobium minimal and yeas...
