The open reading frame alr1585 of Anabaena sp. strain PCC 7120 encodes a heme-dependent peroxidase (Anabaena peroxidase [AnaPX]) belonging to the novel DyP-type peroxidase family (EC 1.11.1.X). We cloned and heterologously expressed the active form of the enzyme in Escherichia coli. The purified enzyme was a 53-kDa tetrameric protein with a pI of 3.68, a low pH optima (pH 4.0), and an optimum r...

BACKGROUND AND OBJECTIVES Synthetic dyes are recalcitrant to degradation and toxic to different organisms. Decolorization of textile wastewaters is one of the major concerns since last decades. Physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. Biological treatments can be more convenient. In the present study, an attempt has been made for de...

Food colors are added to different types of commodities to increase their visual attractiveness or to compensate for natural color variations. The use of these additives is strictly regulated in the European Union, the United States, and many other countries worldwide. There is a growing concern about the safety of some commonly used legal food colorants and there is a trend to replace the synt...

Batik is Indonesia's cultural heritage where each region has its own characteristic style and different batik motifs. dyes can be obtained from synthetic natural dyes. In this research the synthesis of betel nut powder with wax paraffin into ink. The was carried out on a tool that had been made main components, namely reservoir, heating system, an automatic stirrer system temperature readings u...

Most of the dyes are carcinogenic and mutagenic in nature. Plants potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed design an efficient hydroponic system screen ornamental plant species for removal synthetic solution triarylmethane Methylene Blue (MB) diazo Congo Red (CR). plants selected screening Trachyspermum ammi, Tagetes erecta, Hibis...
