Natural dyeing is a rather ancient method. It known that self-growing, agricultural plants in Nature have been used since times as material for painting parts such leaves, fruits, flowers, branches, seeds, stems and roots. Plants the shades obtained from these are important sources of natural dyestuffs. Nowadays, with development technology, methods gradually losing their importance. But, carpe...

Aims: The study’s objective is to isolate, characterize pigment-producing bacteria from marine soil and optimize culture parameters such as pH, temperature, carbon, nitrogen sources enhance the pigment production. obtained was used dye cotton fabrics woollen thread.
 Place Duration of Study: samples were collected Marina beach, Chennai, Tamil Nadu study carried out at Department Animal Bio...

With the invention of dyeing with mordant from 4500 BC, plants, dye insects and seashells found in nature began to be used as a source were until chemical synthesis natural pigments 1856 Today, life trends have become important again. Humanity has protect best way polluted world make use it sustainably. The production dyestuffs without harming human health ecology is an issue that needs focused...

The process of assessing the public health risk of exposure to particular environmental contaminants is complicated and full of assumptions and uncertainties (1,2). However, the problems of assessing risks for chromium exposure are unusually complex (3,4). The problems posed by current investigations of chromiumcontaminated soil in northern New Jersey (5), in part, provided the impetus for a co...

Aloe barbadensis miller (Aloe vera) aside being a potent antioxidant with effects attributed to the phytoconstituents (anthraquinone), can also serve as natural dyes. This study explored staining potentials of A. extract on microbial specimens in modified Gram’s technique. The plant was washed; shrubby edges leaves were scraped off and each leaf cut open expel gel content. dried grinded materia...

Gram stains were performed on strains of Actinomyces bovis, Actinomyces viscosus, Arthrobacter globiformis, Bacillus brevis, Butyrivibrio fibrisolvens, Clostridium tetani, Clostridium thermosaccharolyticum, Corynebacterium parvum, Mycobacterium phlei, and Propionibacterium acnes, using a modified Gram regimen that allowed the staining process to be observed by electron microscopy (J. A. Davies,...

The use of synthetic dyes in the textile industry is mostly non-degradable, which are carcinogenic and pollute environment severely. Natural have gained significant attention recently due to their potential mitigate environmental challenges associated with colorants. This investigation centered around extraction natural sourced from mahogany trees exploration environmentally friendly techniques...

Unmordanted haematein in aqueous solution varies in colour from yellowish orange at pH 3 to bluish magenta at pH 9. In the presence of aluminium sulphate, the colour of solutions of haematein at any particular pH depends on the number of aluminium atoms to each molecule of haematein. At pH 4-6 the colour varies from yellowish orange through dull red to rose as the number of aluminium atoms to e...
