Long-term stability is a key property of enzyme membranes that can be used for biosensors, bioreactors, and bio-fuel cells. This review discusses factors that decrease the stability, and provides two examples of enzyme membranes, a polyion complex membrane and a cellulose membrane, with which stability loss can be avoided. By using these materials, long-term stability was improved. These suppor...

in this research, effect of vermicompost and plant growth promoting rhizobacteria (pgpr) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at karaj research institute of forest and rangelands. experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...

responses of twenty chickpea genotypes to drought stress were evaluated in the farm of college of agricultutre, razi university, kermanshah, iran in 2006-2007. the experiment was carried out in randomized complete block design with three replications under two water stress and non-stress conditions. the results showed significant differences among the genotypes for most of the traits. maximum y...

background & aim:combretaceae family is   known for efficacy in the management of sickle cell disorder (scd). based on   the earlier reports of anti-sickling property of terminalia genus the study investigates in vitro antisickling properties of terminalia arjuna and terminalia   bellirica. experimental: anti-sickling   assay of methanolic and aqueous extract of t. arjuna and t. bellirica   on ...

We propose a mechanism for the stabilization/destabilization of cell membranes by multivalent ions with an emphasis on its implications for the division and fusion of cells. We find that multivalent cations preferentially adsorbed onto a membrane dramatically changes the membrane stability. They not only reduce the surface charge density of the membrane but also induce a repulsive barrier to po...

We find that multivalent cations preferentially adsorbed onto a membrane dramatically change the membrane stability.

Obtaining well-ordered crystals is a major hurdle to X-ray structure determination of membrane proteins. To facilitate crystal optimization, we investigated the detergent stability of 24 eukaryotic and prokaryotic membrane proteins, predominantly transporters, using a fluorescent-based unfolding assay. We have benchmarked the stability required for crystallization in small micelle detergents, a...

Anion exchange membrane (AEM) electrolysis aims to combine the benefits of alkaline electrolysis, such as stability cheap catalyst and advantages proton-exchange systems, like ability operate at differential pressure, fast dynamic response, low energy losses, higher current density. However, today, AEM is limited by AEMs exhibiting insufficient ionic conductivity well lower activity stability. ...
