Genetically Modified Organisms refers to the organism whose genetic structure is modified. This technique helps the human race for the production of products at high scale and quality.
Total number of techniques which are patented 148 patents. Some of the interesting patented techniques are given below.
Patent No: 4,945,052 titled ‘Production of a Vitamin C precursor using genetically modified organisms’ with the abstract: An enzyme for conversion of 2,5-diketo-D-gluconate (2,5-DKG) to 2-keto-L-gulonic acid (2-KLG) and a genetically modified organism that expresses all the fermentation enzymes needed to convert glucose to 2-KLG (a precursor to ascorbic acid) using the new enzyme are described. Preferably, the organism is Erwinia citreus, or a mutated strain of Erwinia citreus, unable to use 2,5-DKG or 2-KLG as a sole carbon source, into which the gene for a 2,5-DKG reductase, produced by Corynebacterium sp., SHS 752001, has been inserted. The preferred transformed organism expresses the fermentation enzymes Erwinia citreus normally expresses for fermentation of glucose to 2,5-DKG and, in addition, an enzyme Corynebacterium sp.
SHS 752001 expresses for fermentation of 2,5-DKG to 2-KLG.
Patent No: 6,686,194 titled ‘Method and device for selecting accelerated proliferation of living cells in suspension’ with the abstract: The present invention relates to a method and a device for selecting accelerated proliferation of living cells in suspension. The culture apparatus (2) of the present invention enables cells to proliferate in suspension over unlimited periods of time. Natural selection results in the accumulation of genetic variants which are increasingly better adapted to the chosen culture conditions. The organisms used can be prokaryotic or eukaryotic. The organisms used can be naturally occurring organisms or genetically modified organisms. The culture apparatus of the present invention is also suitable for using continuous, periodical or conditional culture conditions. The physical and chemical characteristics of the culture media used can be chosen by the user. The requirement that a population of cells proliferates exclusively in suspension in continuous culture conditions is satisfied by the periodical transfer of the organism suspension from a first culture vessel into a second culture vessel. After the transfer, the first culture vessel is subjected to a sterilizing treatment and the sterilizing agent is optionally neutralized, so that the first culture vessel is ready for the culture to be transferred back from the second culture vessel. The second culture vessel is then sterilized and neutralized.
Patent No: 6,599,717 titled ‘Invertebrate vascular endothelial growth factor receptor’ with abstract: Vascular Endothelial Growth Factor Receptor (dmVEGFR) nucleic acids and proteins that have been isolated from Drosophila melanogaster are described. The dmVEGFR nucleic acids and proteins can be used to genetically modify metazoan invertebrate organisms, such as insects and worms, or cultured cells, resulting in dmVEGPR expression or mis-expression. The genetically modified organisms or cells can be used in screening assays to identify candidate compounds which are potential therapeutics that interact with dmVEGFR protein. They can also be used in methods for studying dmVEGFR activity and identifying other genes that modulate the function of, or interact with, the dmVEGFR gene.
Patent No: 6,420,548 titled ‘Method for regulating transcription of foreign genes’ with the abstract: The present invention relates to a method of regulating the transcription of transgene in genetically-modified organisms. More specifically, the invention relates to the use of expression vectors harboring the coding sequence of a gene of interest under the transcriptional control of promoting sequences for which activity is regulated by the presence of nitrogen.
