B. amyloliquefaciens TCCC 11319, a new Cr(iii)-tolerant bacterium for chromium-tanned leather shaving disposal

Abstract

A strain of B. amyloliquefaciens, TCCC11319, was isolated from tannery soil and identified by 16S rRNA gene sequencing.

Leather‐Promoted Transformation of Glucose into 5‐Hydroxymethylfurfural and Levoglucosenone

“…The high Cr content leads to challenges in terms of waste treatment, and heavy pollution is associated with the treatment of tanned leather scrap and tanning baths. Hence, finding alternative uses of waste chromium‐containing leather is of interest . In this respect, some processes have recently been developed to recycle leather and use it in different applications (e.g., pigments) .…”

“…Hence, finding alternative uses of waste chromium-containing leather is of interest. [29][30][31][32][33][34][35] In this respect, some processes have recently been developed to recycle leather and use it in different applications (e.g.,p igments). [36,37] With respectt oc atalysis, chromium-tanned leather can be regarded as ah eterogeneous chromium-based catalyst embedded in an organic support composed of collagen and other skin components (proteins, amino acids;see Scheme 2f or at entative structure of the Cr complex formed with leather;o ther types of cross-linking Cr species may also be present).…”
