Biofertilizer Technology and Integrated Plant Nutrient Management
Keywords Beneficial microorganisms, rhizosphere, biofertilizers, soil fertility, crop production, sustainable agriculture, integrated plant production, evaluation, crops, inorganic fertilizers, soil fertility, organic fertilizers, fertilizer application, nutrients, organic matter, plant nutrition, cropping systems. Introduction Biofertilizer is a substance which contains living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Biofertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting substances producing healthy plants. Biofertilizers ...

Keywords Microarrays, biosensors, genomic analyses, clinical trials, microreactor. Introduction Biochip is a set of diminished microarrays that are placed on a strong substrate that allows many experiments to be executed at the same time to obtain a high throughput in less time. This device contains millions of sensor elements or biosensors. These are not electronic devices. Biochip can be considered as a microreactor that can detect a particular analyte like an enzyme, protein, DNA, biological molecule, or antibody. Biochip, a bio-microarray device, has been extensively studied and developed to enable large-scale genomic, proteomic, and functional genomic analyses. Due to the ...
Read MoreBasic Tools Used in Genetic Engineering
Keywords Recombinant DNA, genetic engineering, genes, gene cloning, genetic manipulations. Introduction Basic tools are necessary for the process to generate recombinant DNA molecules which are enzymes, vectors, and host organisms. The most important enzymes required for genetic engineering are the restriction enzymes, DNA ligase and alkaline phosphatase etc. Each DNA strand contains thousands of genes. Genetic engineering is the process of using gene cloning and other genetic manipulations to isolate specific genes and use it for research and other purposes. Tools Used in Genetic Engineering The list of ten tools/enzymes that are commonly used in genetic engineering are discussed below. ...
