| Abstract: | We have described a novel red biochrome, 514 Da in size, produced by solid-state cultivation of a bacterial isolate obtained
from garden soil. The growth requirements of the isolate, the chemical characteristics of the biochrome produced, and the
application of the biochrome in dying of silk, wool, and cotton fabrics have been studied. The biochrome obtained after 52 h
of incubation and having a λ
max of 535 nm was used for dyeing the fabrics. We found that silk, wool, and cotton fabrics dyed with this new natural red compound
have high color strength values and dye uptake along with good color fastness as well as antibacterial activity. |
