Quantitative models are required to engineer biomaterials with environmentally responsive properties. With this goal in mind, we developed a model that describes the pH-dependent phase behavior of a class of stimulus responsive elastin-like polypeptides (ELPs) that undergo reversible phase separation in response to their solution environment. Under isothermal conditions, charged ELPs can underg...

the anionic surfactant sodium dodecyl sulfate (sds) was degraded by novel strain ofpseudomonas aeruginosa kgs under accession no. jq328193, which was isolated from carwash wastewater. the purpose of this research was to study different optimization conditionsrequired for enhancing the biodegradation of sodium dodecyl sulfate p. aeruginosa kgs.influence of different physicochemical factors such ...

bacillus sp. guf8, isolated from acidic soil samples of a tea farm was identified as bacillus cereus, based on 16s rdna sequencing and standard bacterial identification methods. following optimization of enzyme production, the resulting α-amylase was purified by acetone precipitation and ion exchange chromatography. consequently, thermostability and kinetic parameters of the purified enzyme wer...

bioleaching of spent refinery processing catalysts using adapted indigenous strains ofacidithiobacillus ferrooxidans to recover ni and mo, and the separation of ni from bioleaching liquor usingiron magnetic nanoparticles were optimized in this study. bioleaching optimization was performed usingcentral composite design (ccd) method to optimize temperature (32 to 38oc), initial ph (1.5 to 2), par...

In view of the increase in Saccharomyces cerevisiae mannan content, the culture condition for S.cerevisiae were optimized in this study. The influence of culture condition such as original pH, inoculum size, and temperature on mannan production were evaluated using Response surface methodology. The mathematical model was established by the quadratic rotary combination design. with the order of ...

background gastroesophageal reflux disease (gerd) is a common problem seen in pediatrics and adolescents. the bravo tm ph monitoring system is a capsule that detects and quantifies the severity of reflux disease. this test is also valuable for evaluation of patients with extra-gastrointestinal manifestations of gerd such as asthma, chronic cough, hoarseness, aspiration pneumonia, and pre/post f...

Aortic stenosis (AS) leads to pulmonary hypertension (PH) and right ventricle (RV) failure. Our goal was to describe mortality related to postoperative complications in PH patients undergoing transcatheter aortic valve replacement (TAVR). Ninety-three TAVR patients were analyzed (controls, sPAP < 50 mmHg; cases, sPAP ≥ 50 mmHg). Significant findings in cases included increased mortality (365 da...

In this study, renewable marine cellulose from red algae Gracilaria verrucosa was utilized for the production of bioethanol. Bioethanol from the red alga cellulose was produced by the enzymatic hydrolysis and fermentation methods and the conversion value of the cellulose in Gracilaria verrucosa was estimated. Trichoderma viride fungus and Zymomonas mobilis bacterium were used for enzymatic hydr...

Three alkaline protease producing gram positive, spore forming Streptomyces (J1, J2 and J3) were isolated from alkaline soil (pH range: 9-10) samples collected from Central Soil Salinity Research Institute (C.S.S.R.I), Lucknow. On the basis of halo zone, morphology, texture and microscopic characteristics they were identified as Streptomyces. Further characterization both genetically and phenot...
