Proteases from an Environmental Isolate of Pseudomonas Aeruginosa MCCB 123 and Their Applications

In the present study,heterotrophic protease producing bacterial isolates were screened for protease activity and a potent protease producing bacterial isolate was selected,identified and coded as Pseudomonas aeruginosa MCCB 123.The organism was capable of producing three different types of enzymes each having potential industrial applications.The non-toxic nature of the bacterial strain and the relatively non-toxic nature of three enzymes suggested their poetential application in various industries.Application of LasA protease and beta-1,3 glucanase in DNA extraction is a promising area for commercial utilization. LasB protease can find its potential application in detergent and tanning industries.As on today Bacillus sp.has been the source of commercial proteases,and the ones produced form P.aeruginosa 123 can pave way for making the industrial and biomedical processes more cost effective and refined.

Waste Water Treatment Using Low Cost Natural Adsorbents

Heavy metals are major toxic pollutants with severe health effects on humans. They are released into the environment from a variety of industrial activities. Cadmium, lead, zinc, chromium and copper are the most toxic metals of widespread use in industries such as tanning, electroplating, electronic equipment manufacturing and chemical processing plants. Heavy metals contribute to a variety of adverse health environmental effects due to their acute and chronic exposure through air, water and food chain. Conventional treatment methods of metal removal are often limited by their cost and ineffectiveness at low concentrations. Adsorption, the use of inactivated biomass as adsorbents offers an attractive potential alternative to their conventional methods. Mango peel and Alisma plantago aquatica are naturally occurring and abundant biomass can offer an economical solution for metal removal.The Cd(II), Pb(II), Zn(II), Cr(III) and Cu(II) adsorption by milled adsorbents of mango peel and Alisma plantago aquatica were evaluated in batches.
