Evaluation of antagonistic Pseudomonas against root lesion nematode of tea

The tea root lesion nematode, Pratylenchus loosi, has been shown internationally to be a serious nematode pest causing yield losses in tea plantations. It is one of the most important crop loss agents in Iran, which affect quantity and quality of tea leaves. Biological control agents represent an innovative alternative to agrochemicals and have potentials […]

Heavy metal pollution, a global problem and its remediation by chemically enhanced phytoremediation: A Review

Heavy metal contaminated soils are very hard to restore. This type of soil pollution is primarily attributed to anthropogenic activities, including, smelting, mining and various industrial activities. The world’s heavily effected areas from heavy metal pollution have been proving as health risks to more than 10 million people in various countries. Linfen in China people […]

Impact of heavy metals and Hsp Response

Heavy metals are natural constituents of the earth’s crust, but indiscriminate human activities have drastically altered their geochemical cycles and biochemical balance. Heavy metals such as Iron, copper, Zinc, Nickel, Molybdenum are essential for normal biological functioning. Heavy metals such as Mercury, Lead, and Cadmium are biologically non-essential, but are important metals for industrial applications. […]

Screening of PHA (poly hydroxyalkanoate) producing bacteria from diverse sources

Synthetic plastics are non-degradable and cause waste disposal problems leading to environmental pollution. Bioplastics (polyhydroxyalkanoates) are considered good substitutes for petroleum derived synthetic plastics because of their similar physical and chemical properties. Main advantage of bioplastics is that they are of biological origin and can get degraded completely to CO2 and water under natural environment […]

Inhibitory effect of different plant extracts and antifungal metabolites of Trichoderma strains on the conidial germination and germ tube growth of Colletotrichum capsici causing chili anthracnose

Antifungal activities of twenty four plant extracts and secondary metabolites of five Trichoderma strains were tested against conidial germination and germ tube growth of Colletotrichum capsici. Hundred percent inhibition of conidial germination and shortest germ tube formation of Colletotrichum capsici were recorded in Azadiracta indica (leaf), Ocimum sanctum (leaf) and Curcuma longa (rhizome) extracts after […]
