Actinomycetes are known to produce an extensive range of bioactive compounds as well as variety of enzymes having multiple biotechnological applications. They are an important source of lignocellulose hydrolyzing enzymes and constitute considerable proportion of the soil or aquatic micro-flora responsible for degradation of biomass in natural environment. Presently, most of the commercially exp...

The manufacture of paper generates significant quantities of waste water; which can have deleterious effects on the receiving waters; therefore there is a need to find a treatment process which can minimize these effects considerably. The raw wastewater from paper and board mills can be potentially very polluting. This paper reveals the results of laboratory experiments using a sequential batch...

In the pulp and paper industry, the water use minimization is a constant target. One way to reduce water use is to recycle the effluent in a closed-cycle concept. In paper mills, the main source of liquid effluent is the so-called whitewater, which is the excess water, originated from pulp stock dewatering and other fibre contaminated water. This research studied the reuse of paper mill whitewa...

The possible ecotoxicological effects of a paper and pulp mill effluent were investigated by measuring selected contaminants and biomarkers in caged Nile tilapia (Oreochromis niloticus) and sharptooth catfish (Clarias gariepinus) from the Karnaphuly River, Bangladesh. Fish were caged for 28 d at two upstream reference sites (2 and 4 km) and four downstream sites (3, 5, 8, and 12 km) from the ef...
