Mechanism of Cr (VI) reduction by Pichia guilliermondii ZJH-1.

ABSTRACT:

Background

Chromium is one of the most used toxic heavy metals. A large amount of chromium waste is discharged into the environment every year, causing serious environmental pollution, especially the pollution of soil and water by hexavalent chromium. Eliminating hexavalent chromium is the primary challenge to achieve a pollution-free environment.

Objectives

This study aims to understand the mechanism of Pichia guilliermondii's reduction of hexavalent chromium through enzymatic characteristic, oxidative stress response, and reduction product.

Material and methods

The strain Pichia guilliermondii ZJH-1 was isolated and stored in our laboratory. The hexavalent chromium uses 1,5-diphenyl carbazide method (DPC) to measure. The UV spectrophotometer was used t
