Biocontrol of Meloidogyne incognita in Lycopersicon esculentum with AM Fungi and Oil Cakes
Anuja Bharadwaj,Satyawati Sharma
Plant Pathology Journal , 2006,
Abstract: Currently chemical pesticides are the major means to control nematode-induced diseases but they are neither economical nor ecofriendly. Alternative methods are being sought to reduce the amount of chemical pesticides required. Arbuscular mycorrhizal fungi have been reported to reduce the infestation of root-knot nematodes on vegetable crops. Amendment of soil with some oil cakes has been found effective. A study was conducted on exploitation of the combined effect of AM with three different oil cakes Azadirachta indica, Brassica campestris and Ricinus communis oil cakes in controlling the root knot nematode Meloidogyne incognita. Combined use of AMF and cakes resulted in reducing the galling and nematode multiplication thus improving the plant growth and yield. The best results pertaining to AM root infection, nematode reproduction and plant growth and yield were obtained with the combination of AMF and R. communis oil cake.
Effect of Some Plant Extracts on the Hatch of Meloidogyne incognita Eggs
Anuja Bharadwaj,Satyawati Sharma
International Journal of Botany , 2007,
Abstract: Root-knot nematodes are one of the major limiting factors affecting plant growth and yield. Currently, synthetic pesticides are principle means used to control the nematodes but natural products may provide a safer alternative. Nematicidal compounds have been identified in a wide diversity of plant species. A study was conducted to evaluate potential of aqueous extracts from Azadirachta indica, Carica papaya, Ocimum sanctum, Ricinus communis and Tagetes patula, in controlling the hatch of eggs of the root-knot nematode, Meloidogyne incognita. Five concentrations of water soluble extracts from the five plant species were filtered, added to petri dishes and infested with eggs of M. incognita. The best results were obtained with O. sanctum, with no hatching within 48 h vs. 34.8% in the control.
Reducing Phosphorous Requirement Using AM Fungi in Mulberry Grown under Alkaline Conditions
Anuja Bharadwaj,Satyawati Sharma
Journal of Agronomy , 2006,
Abstract: Most of the soils fix phosphorus (P) and make it unavailable for plant growth. Tropical soils, specifically salt affected, are deficient in P. It is estimated that major portion (~75%) of super phosphate applied is fixed and only 25% is available for plants. India has a large area of alkaline soils and to reclaim these soils heavy doses of chemical fertilizers are applied. The use of chemicals is neither economical nor ecofriendly. Biofertilizer like mycorrhizal fungi could play a very important role in this regard. They have been recognized as potential biotechnology tool for enhancing plant growth as well as for reclamation of wastelands. Arbuscular Mycorrhizal Fungi (AMF) are well known for phosphorus solubilization, increased plant nutrient uptake and in control of root diseases. Mulberry (Morus alba), an important cash crop for sericulture, does not grow well in alkaline soils due to their high pH and deficiency of nutrients and requires heavy doses of NPK for its proper growth. To propagate sericulture in salt affected area, it is important to meet the nutrient requirement of mulberry. Exploitation of AMF can meet great demand of phosphorus besides other nutrients in alkaline soils. A study was conducted to evaluate potential of AMF in reducing the amount of P required for proper growth of M. alba var. Sujan Puri in alkaline soils. Four concentrations i.e., 0, 25, 50, 75 and 100% of recommended dose of P were applied with AMF. The results suggested a net saving of 25% of the recommended dose of inorganic P i.e., triple super phosphate, with AMF in alkaline soils for the proper growth of mulberry.

Biology and Medicine , 2011,
Abstract: Leprosy is a crippling disease with an associated social stigma. The disease is widely prevalent in India, which is oneof the endemic areas for the disease. Its oral manifestations though described, is very rare. Twenty established casesof leprosy from various hospitals were taken up in the study. Thirteen were in the lepromatous variety and sevenwere in the tuberculoid variety. None of the cases had any oral lesions. Biopsies were taken from the buccal mucosaand histopathological sections were studied by Hematoxylin and eosin, Wade-fite and S-100 immunoperoxidasestain. The results showed positivity for Mycobacterium leprae in 5 cases of lepromatous leprosy by Wade fittechnique. S-100 immunoperoxidase stain revealed nerve changes in the form of fragmentation in cases positive forMycobacterium leprae. These findings show that even in the absence of clinically observable oral lesions, tissuechanges in oral tissues do happen in some cases of leprosy and the causative organism Mycobacterium leprae canbe demonstrated.

Indian Phytopathology , 2011,
Abstract: Antifungal efficacy of non-conventional and safe treatments were evaluated against aflatoxin producing fungus Aspergillus flavus using bioassay and as dressings during storage for different types of rice grains. The radial growth of the fungus Aspergillus flavus was restricted on PDA medium with increasing concentration of different treatments viz., turmeric, cloves and potassium sorbate using food poison technique. Turmeric treatment @ 0.1% (dry seed dressing) gave 43 per cent control followed by 36 and 27 per cent control in potassium sorbate and clove treatments, respectively. At 0.4% concentration, clove treatment gave 100 per cent control of A. flavus followed by 53 and 51 per cent control in potassium sorbate and turmeric treatments, respectively. Exposure to microwave heat for 2 min at 100% power retained the moisture content of grains and inhibited more than 50% fungal growth without adversely affecting the cooking quality of rice grains. The cooking quality of stored rice grains also remained unaffected irrespective of different treatments and storage conditions even after 15 months of storage. The occurrence of fungi including A. flavus increased during successive storage irrespective of the rice types up to 12 months of storage. High fungal incidence was recorded in unpolished rice grain (51.5%) followed by polished rice grain (43.0%) and whole paddy grain (5.5%). Amongst the storage conditions, 20.1% and 13.1% incidence of A. flavus was recorded on grains stored under godown conditions at a rice mill and those stored in the scientific seed stores, respectively. Fungal incidences of 20.4% and 12.8% were found associated with grains stored in jute bags and polylined jute bags, respectively. Treatment with potassium sorbate, turmeric, cloves and microwave heat exhibited 67.3, 62.7, 37.3, and 5.9 percent control of A. flavus, respectively during storage for 15 months under ambient conditions.

Manjusha Rani, Anuja Agarwal, Yuvraj Singh Negi
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.21010
Abstract: The paper describes the synthesis of pH sensitive interpenetrating polymeric network (IPN) beads composed of chi-tosan, glycine, glutamic acid, cross linked with glutaraldehyde and their use for controlled drug release. The drug was loaded into beads by varying their composition such as, amount of crosslinker glutaraldehyde, ratio of chitosan, glycine and glutamic acid. The beads were characterized by fourier transform infrared (FTIR) spectroscopy to confirm the cross linking reaction and drug interaction with crosslinked polymer in beads, Scanning Electron Microscopy (SEM) to understand the surface morphology and Differential scanning calorimetry (DSC) to find out the thermal stability of beads. X-Ray Diffraction (XRD) investigation was carried out to determine the crystalline nature of drug after loading into chitosan-glycine-glutamic acid IPN beads. Results indicated amorphous dispersion of chlorpheniramine maleate (CPM) in the polymeric matrix. The swelling behavior of the beads at different time intervals was monitored in solutions of pH 2.0 and pH 7.4. The release experiments were performed in solutions of pH 2.0 and pH 7.4 at 37oC using chlorpheniramine maleate (CPM) as a model drug. The swelling behavior and release of drug were observed to be dependent on pH, degree of cross linking and their composition. The results indicate that the cross linked IPN beads of chitosan-glycine-glutamic acid might be useful as a vehicle for controlled release of drug. The kinetics of drug release from beads was best fitted by Higuchi’s model in which release rate is largely governed by rate of diffusion through the matrix.
