In-Situ Soil Cementation with Ureolytic Bacteria by Surface Percolation

A New Method for the Screening of Ureolytic Bacteria Inducing Calcium Carbonate Precipitation

At present several studies are evaluating biological calcite precipitation as it has laid the concept of bioconcrete as a self-healing material which may be a green and more sustainable component for future architecture. This paper reports a 96 wells plate based rapid and easy method for the screening of urea hydrolyzing/calcite-precipitating bacteria. Arsenazo III was used as a colorimetric in...

An enzymatic and bioinformatics study of native cutinase bacteria

Cutin is a polymer that is constructed in plants by the condensation and oxidation of fatty acids and plays a key role in the protection of plants against pathogens. Cutinase is a hydrolase enzyme that breaks down the cutin. The purpose of this study was to extract cutin from red apples with oxalate buffer, cutinase enzyme activity assay in LB culture, and bioinformatic analysis. To attain thes...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
