Cell Fusion- Types and Significance Until recently, cells were thought to be integral and discrete components of tissues, and their state was determined by cell differentiation. However, under some conditions, stem cells or their progeny can fuse with cells of other types, mixing cytoplasmic and even genetic material of different (heterotypic) origins. Cell fusion is an important cellular … Read moreCell Fusion- Types and Significance
Embryo Transfer Embryo refers to the early developmental stage of an animal while it is in the egg or within the uterus of the mother. In humans the term is applied to the unborn child until the end of the seventh week following conception; from the eighth week, the unborn child is called a fetus. Embryo transfer refers to … Read moreEmbryo Transfer
Submerged fermentation- Principle, Methods, Substrate, Applications, Advantages and Limitations Fermentation is the technique of biological conversion of complex substrates into simple compounds by various microorganisms such as bacteria and fungi. In the course of this metabolic breakdown, they also release several additional compounds apart from the usual products of fermentation, such as carbon dioxide and alcohol. … Read moreSubmerged Fermentation
Plant Tissue Culture Plant Tissue culture is the in vitro aseptic culture of cells, tissues, organs or whole plant under controlled nutritional and environmental conditions often to produce the clones of plants. It refers to a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium … Read morePlant Tissue Culture
Micropropagation- Stages, Types, Applications, Advantages, Limitations Micropropagation is the rapid vegetative propagation of plants under in vitro conditions of high light intensity, controlled temperature, and a defined nutrient medium. The technique has been applied to a substantial number of commercial vegetatively propagated plant species. Plants can be propagated by sexual (through the generation of seeds) … Read moreMicropropagation- Stages, Types, Applications, Advantages, Limitations
Solid State Fermentation (SSF) Solid State Fermentation (SSF) is a fermentation method used by several industries like the pharmaceuticals, food, textile etc., to produce metabolites of microorganisms using solid support in place of the liquid medium. It is defined as the growth of microbes without free-flowing aqueous phase. The SSF is alternative to submerged fermentation for … Read moreSolid State Fermentation (SSF)
