An extremely haloalkaliphilic archaeon Natrinema sp. SSBJUP-1 showing potent amylolytic and proteolytic activities was isolated from the saline alkaline Lonar Lake, India. Amylase and protease were active over the neutral to alkaline pH range from 6 to 9. Amylase was more stable over a narrower temperature range of 40-60C than the protease but had the higher optimum (55C) for activity. By contr...

was stable, his skin became irritable and hot with extensive reddening. Though in bed in a warm room he felt cold. During the next three days the skin became tender, and large areas of pustulation developed. Subsequently there was widespread peeling of the skin, and crusting developed on the face and neck. On admission to hospital there was generalized cutaneous erythema and scleral jaundice. T...

Two phase flow in a horizontal tube has widespread applications, particularly in the condensers of refrigeration and air conditioning systems. Pressure drop prediction is especially important for condensers because the local condensing temperature is a function of local pressure, affecting the mean temperature difference in the heat exchanger. In the present analysis, two phase flow is treated ...

The aim of the present study reported here is to examine the production, purification and characterization of the enzyme laccase from the mushroom Hypsizygus ulmarius. The culture conditions were optimized for the maximum production of enzymes with different parameters such as incubation time, carbon, nitrogen sources. The enzyme was purified by ammonium sulphate precipitation and partially cha...

Phospholipids (PLs) are significantly utilized in different areas of food, pharmaceutical and cosmetic products as emulsifiers, stabilizers and antioxidants. The properties of PLs can be modified with a view to improve its inherent properties like emulsification and oxidative properties as well as tailor made technological and physiological properties. Advancement of biotechnology serves as a v...

An indigenous wood rotting edible Lentinus kauffmanii isolated from Keeriparai forest of Western Ghats was studied for extracellular peroxidase production. Peroxidases are major extracellular lignolytic enzymes involved in lignocellulosic degradation. Physical factors such as pH, temperature and nutritional factors such as carbon, nitrogen sources and amino acids were standardized for the growt...

4 ABSTRACT: Anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW) 5 is promoted as an energy source and more recently as a GHG mitigation measure. In this context, AD 6 systems operating at thermophilic temperatures (55-60C) – compared to mesophilic temperatures 7 (35-40C) – have the unique feature of producing hygienic soil conditioners with greater process 8 effici...
