Cleaner Production of Chromium Oxide from Low Fe(II)-Chromite

Chromium bioremediation by Alcaligenes sp. strain newly isolated from chromite mine of Sabzevar

In this work, CKCr-6A strain was found to be highly resistant to some toxic heavy metals such as Cr+6, Cr+3, Cu+2, Co+2, Cd+2, Pb+2, Hg+2, U+6, tellurium, and selenite. Herein, high chromate tolerance of an isolated strain is reported with a high minimum inhibitory concentration value of 80,000 mg/L and the ...

Best Practices in Cleaner Production

“integrating Cleaner Production into Sustainability

Bacterial Cellulose biosynthesis is one of the most important applied biochemical processes in biology. In order to explain the detailed molecular events of bacterial cellulose biosynthesis, we discuss in this work, the different steps required for bacterial cellulose formation and crystallization from sugar cane and honey. The potential of organisms to produce biocellulose fibers was analyzed....

Effect of Neutrophils on Nitric Oxide Production from Stimulated Macrophages

Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whethe...

Photocatalytic Removal of Hexavalet Chromium from Aqueous Solution Using Zinc Oxide Nanoparticle Stabilized On Zeolite

Backgrounds & objectives: Heavy metals, such as chromium, are the most common pollutants usually found in high concentrations in industrial wastewater and cause damages to aquatic environments and endanger the health of living organisms, especially human. Therefore, the purpose of this research was to investigate the photocatalytic removal of hexavalent chromium from aqueous solution using UV/Z...
