摘要

Microbial decolourisation is seen as environmentally friendly technique for removing the colouring compounds from distillery waste water. Some groups of fungi possess decolourisation ability either via adsorption of colouring components by mycelia or via production of active oxygen, from hydrogen peroxide in a process coupled to sugar oxidase, which degrades melanoidtns and thus reduces the colour of distillery effluent. In the present study, feasibility of using Pseudomonas putida for decolourisation of distillery effluent has been demonstrated. This strain had the ability to extra-cellularly convert glucose into gluconic acid and hydrogen peroxide. The hydrogen peroxide, secondarily produced by this enzymatic oxidation decolourised the distillery effluent by oxidizing melanoidins. Pseudomonas putida immobilized in calcium alginate beads showed two and a half fold more decolourisation than free cells. The concentration of glucose, cell density and pH of the medium were found to be critical for decolourisation. The improved colour removal efficiency was obtained by replenishment of glucose periodically at six hours of intervals. Colour reducing ability of Pseudomonas putida was also obserued when lactose or whey was added to the distillery effluent. Whey is the waste from cheese manufacturing industry and contains lactose, which is catabolised by Pseudomonas putida into glucose and galactose. Glucose oxidase in Pseudomonas putida transforms glucose, produced after the hydrolysis of lactose, into gluconic acid and hydrogen peroxide which leads to reduction in colour of the distillery effluent.
