Our investigation of integrated biological control (IBC) started with an assay testing activity of the predacious yeast Saccharomycopsis crataegensis UFMG-DC19.2 against Penicillium digitatum LCP 4354, a very aggressive fungus that causes postharvest decay in oranges. Under unfavourable environmental conditions, the yeast showed a high potential for control (39.9% disease severity reduction) of...

Five different sporulation medium such as tryptone yeast extract (TYE) broth, tryptone glucose yeast extract (TGYE) broth, minimal media, Sucrose salt medium, Arret & Krishbaum (AK)sporulation agar were screened for spore production in Bacillus megaterium ATCC 9885. During this study, it was observed that out of different combinations of tryptone, yeast extract and dextrose sporulation was maxi...

Saccharomyces cerevisiae, which is a common species of yeast, is by far the most extensively studied model of a eukaryote because although it is one of the simplest eukaryotes, its basic cellular processes resemble those of higher organisms. In addition, yeast is a commercially valuable organism for ethanol production. Since the yeast data can be extrapolated to the important aspects of higher ...

In plants, high capacity tonoplast cation/H(+) antiport is mediated in part by a family of cation exchanger (CAX) transporters. Functional association between CAX1 and CAX3 has previously been shown. In this study we further examine the interactions between CAX protein domains through the use of nonfunctional halves of CAX transporters. We demonstrate that a protein coding for an N-terminal hal...

Using a conditional life or death screen in yeast, we have isolated a tomato (Lycopersicon esculentum) gene encoding a phospholipid hydroperoxide glutathione peroxidase (LePHGPx). The protein displayed reduced glutathione-dependent phospholipid hydroperoxide peroxidase activity, but differs from counterpart mammalian enzymes that instead contain an active seleno-Cys. LePHGPx functioned as a cyt...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

Fish sauce is a fermented product which is used in south Asian countries. In the present study, Caspian Kilka was used to produce the sauce, using either cooked or raw fish subjected to four different treatments: 1) traditional method, where fish and salt were used; 2) an enzymatic method, where fish, salt and proteolytic enzymes, including Protamex and Flavourzyme (Novo Nordisc Co., Bagsvaerd,...

Transfer of mitochondria to daughter cells during yeast cell division is essential for viable progeny. The actin cytoskeleton is required for this process, potentially as a track to direct mitochondrial movement into the bud. Sedimentation assays reveal two different components required for mitochondria-actin interactions: (1) mitochondrial actin binding protein(s) (mABP), a peripheral mitochon...

Considerable interest in the consumption of bread from ancient spelt wheat with superior nutritional properties, easy digestibility and pleasant taste aroma, has arisen recently. Yeast extract (YE) is nowadays frequently used as a natural flavor enhancer for improving organoleptic properties such meaty, cheesy savory attributes different food products. YE product baker?s yeast industry high ric...
