Mashelkar report says modified organisms are intellectual property THE expert group on patent law headed by R A Mashelkar has recommended that microbes like bacteria, fungi and virus should be patented if they have been modified. The committee has also said India cannot limit its patents to new chemical substances …
Many plants introduced to new habitats have fewer microbial pathogens than when in their home range, and have the ability to grow rapidly. Such a combination may make for especially troublesome immigrants.
The bacterial diversity in a tropical soil experimentally polluted with crude oil during a 57 days bioremediation was investigated in five 1 m2 plots using total culturable hydrocarbon utilizing bacteria, heterotrophic bacteria and gas chromatographic analyses. Four out of the five experimental plots received each 4 L of Bonny light …
An attempt has been made to study the soil bacteria, fungi and actinomycetes population in Seabuckthorn stand soil at different altitudinal zones in different seasons. Among different altitudinal zones greater microbial population size was recorded in Seabuckthorn stand soil of middle elevation zone followed by lower elevation zone and lower …
Composting of leaf litter using the epigeic, exotic earthworm Eisenia fetida and the microbial kinetize (Quikompost) was carried out in order to compare their efficacies in waste management. The quantity of leaf litter composted and the biomass (earthworm/microbial) recovered after composting were increased with increasing the quantity of earthworm/microbial kinetizer.
The nitrogen enriched phosphocompost was prepared utilizing the abundantly available green biomass of Lantana camara and supplemented with 12.5 and 25.0 per cent levels of rock phosphate, 1.0% fertilizer nitrogen (urea), 5.0 and 10.0 per cent pyrite or by inoculation with Azotobacter chroococcum and Aspergillus awamori. The compost mix-up was …
Lignocellulosic biomass is the most abundant renewable resource on earth. Lignocellulosic materials, including wood, grass, forest residues, agricultural residues, pulp and paper mill wastes, and municipal solid wastes can be used for bioethanol production. Among these resources, agricultural residues, such as sugarcane bagasse, dominate in terms of tonnage and can …
Shipboard iron- and macronutrient-addition experiment was conducted in the Central Indian Ocean, to investigate the variations of carbon in different forms and its records for plankton activities. Experiments were conducted in four 500-L acrylic barrels with the surface seawater near 24
Intrinsic antibiotic resistance has been a fact of bacterium life since long before humans discovered the use of antibiotic drugs. However, the introduction of pharmaceutical antibiotics in the 1940s and explosion in use ever since dramatically accelerated the spread of antibiotic-resistance genes. Today, the problem of antibiotic resistance is so …
Life evolved when the ocean nickel levels dropped evolution of life was preceded by a great rise in the atmospheric oxygen levels. There are a couple of theories as to what triggered that rise. While both talk about a decrease in the number of bacteria that produce methane (methanogens) and …
India has done a commendable job of collecting and preserving its precious micro-organisms Surinder Sud / New Delhi May 19, 2009, 0:23 IST The issue of patentability of micro-organisms has remained controversial largely because it concerns the high-profile pharmaceutical industry which views these organisms as sources of future drugs. The …
Helsinki Air conditioning in cars cuts out more than 80 per cent of germs, fungal spores and particles from outside air, providing a boon for people with respiratory problems or allergies, German scientists say. In a study released at the European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), a …
zoology Undersea myths The mystery behind the underwater display of natural glow, seen by sailors time and again, has been solved. It is the bioluminescent marine fireworm that secretes a mucous which gives out a green glow to attract mates and ward off predators. Reported in the March issue of …
The relationship of domestic endotoxin exposure to allergy and asthma has been widely investigated. However, few studies have evaluated predictors of household endotoxin, and none have done so for multiple locations within homes and on a national scale. The authors assayed 2,552 house dust samples in a nationwide study to …
Anti-infectives are constantly discharged at trace levels in natural waters near urban centers and agricultural areas. They represent a cause for concern because of their potential contribution to the spread of anti-infective resistance in bacteria and other effects on aquatic biota. We compiled data on the occurrence of anti-infectives published …
The physico-chemical and bacteriological characteristics of ground water samples collected in Dharmapuram village, Kanyakumari district, Tamil Nadu was assessed.
Studies on the bacteriological quality of groundwater samples around the sewage farm in Muttathara-Valiathura area of Thiruvanathapuram district, Kerala was conducted during post-monsoon (November 2007) and pre-monsoon (April 2008) seasons.
