in the present study, we aimed to screen indigenous rhizospheric bacillus strains, capable of producing antiphytopathogenic and plant growth promoting traits. isolate cts-b19 and cts-g24 exhibited quite noticeable antagonistic activity initially against fusarium oxysporum f. sp. ciceri and rhizoctonia bataticola, and, later, against a panel of phytopathogens. partial 16s rrna sequence analysis ...

The use of biotechnology by tanneries has increased in recent years. Enzymes can be applied during different steps of the leather production process: soaking, dehairing, bating, dyeing, degreasing or in effluent and solid waste treatment. This study evaluated the performance of five commercial enzymes in soaking and unhairing/liming by comparing the chemical and coenzymatic processes. Tests wer...

The aim of this study was to investigate the influence thermal treatment and ultrasound on activity β-glucosidase lipoxygenase, enzymes that determine phenolic composition sensory profile virgin olive oil. Enzyme determined spectrophotometrically in model systems consisting commercial their substrates. Thermal performed by tempering substrates at temperatures between 15 40 °C. measured 1 min af...

A reusable enzyme strip for the determination of cholesterol was prepared by co-immobilizing cholesterol esterase (CEase), cholesterol oxidase (COD) and peroxidase (POD) onto alkylamine glass beads affixed on a plastic strip by a nonreactive fixative. The co-immobilized enzymes retained 71.42% of initial activity of free enzymes with a conjugation yield of 11.0 mg g beads and showed optimum act...

Enzymatic biodiesel production has been investigated intensively, but is presently employed industrially only in a 20,000 tons/year pilot plant in China (Du et al. [2008] Appl Microbiol Technol 79(3):331-337). This review presents a critical analysis of the current status of research in this area and accentuates the main obstacles to the widespread use of enzymes for commercial biodiesel transe...

Partially digested gluten fragments from grains including wheat, rye, spelt and barley are responsible for triggering an inflammatory response in the intestinal tract of Celiac Disease (CD) Non-Celiac Gluten Sensitive (NCGS) individuals. Fermentation is effective method to metabolize gluten, with enzymes bacterial or fungal species being released help this process. However, levels commercially ...

OBJECTIVES To find evidence, either corroborating or refuting, for many persisting beliefs regarding the feasibility of carrying out surgical randomised controlled trials with a placebo arm, with emphasis on the challenges related to recruitment, funding, anaesthesia or blinding. DESIGN Systematic review. DATA SOURCES AND STUDY SELECTION The analysis involved studies published between 1959 ...

This paper is devoted to simulate the arc movement in the quenching chamber of the low-voltage circuit breaker. Based on a group of governing equations, a three-dimensional (3-D) arc model is built and solved by a modified commercial code. According to the simulated results, some phenomena such as a ‘bulge’ in front of the arc column, a tail in the rear of the arc column, arc shrinkage near the...

Discrete groups of isometries provide a rich class of groups for detailed study in an undergraduate course in abstract algebra. After developing some geometric tools, we illustrate several important ideas from group theory via symmetry groups. In particular, we consider conjugation, homomorphisms, normal and nonnormal subgroups, generators and relations, quotient groups and direct and semidirec...

Data produced by three dimensional MHD calculations are often difficult to visualize. Here we present a technique to view field lines of vector fields and one to display multiple isosurfaces of scalar fields. These methods do not rely on expensive commercial software and are general enough to be applied to other research sectors where visualization of 3D fields is important. Printed copies of t...
