To-day's Rayon Pulp Industry in Japan

Syntrophic co-culture of Bacillus subtilis and Klebsiella pneumonia for degradation of kraft lignin discharged from rayon grade pulp industry.

In order to search the degradability of kraft lignin, the potential bacterial strains Bacillus subtilis (GU193980) and Klebsiella pneumoniae (GU193981) were isolated, screened and applied in axenic and co-culture conditions. Results revealed that mixed culture showed better decolorization efficiency (80%) and reduction of pollution parameters (COD 73% and BOD 62%) than axenic culture. This indi...

06 New ways to Improve Energy efficiency in Pulp and Paper Industry

The activities of human civilization have imposed a high burden on the environment since the beginning of history on a global scale. That is why energy producers and consumers need to think deeply about the role that energy plays to achieve sustainable development. In this context, the maintenance of the environment, which cannot be replaced, should be taken into account precisely. Rising energ...

Treatment of rayon grade pulp drain effluent by upflow anaerobic fixed packed bed reactor (UAFPBR).

The Rayon grade pulp (RGP) drain effluent of pulp and paper mill was studied to find out pollutant loading and its control measures by low cost and efficient treatment method. Upflow anaerobic fixed packed bed reactor (UAFPBR) with brick ballasts as packing material was used for this purpose. This was compared with conventional anaerobic treatment method. The digested slurry was taken as inocul...

The Biotechnology Industry in Germany and Japan

Biotechnology is considered as one of the key high-technology sectors in the future. It has been increasingly accepted that small, innovative businesses were the major stimulus for the development of this emerging industry. Many studies on new entrepreneurial entrants in biotechnology are mainly addressed to the situation in the United States and neglected developments in other countries. There...
