OBTAINING MICROBIAL L-GLUTAMIC ACID WITH STRAIN CG2 Technical Area This invention is based on Stenotrophomonas sp., which is used in various food products and can also be used in the pharmaceutical and personal care industries as a nutritional supplement. It is related to Microbial L-Glutamic Acid Production in optimum time and conditions with strain CG2 (OM341624). Background of the Invention Nutrition is the most necessary need for a person's survival in life. Protein foods must be consumed to obtain amino acids, which are found in foods and are important for the body, and special supports such as sports foods and food supplements are taken to obtain amino acids in a controlled manner. L-glutamic acid is found in foods as a free amino acid or as a part of the structure of proteins. One of the food additives is L-Glutamic Acid (Monosodium Glutamate). Its formula is C5H3NNaO4. It is the sodium salt of glutamic acid, a natural amino acid that forms the basic building block of protein. L-Glutamic Acid is in the form of white crystalline solid. In terms of solubility, it is easily soluble in water and is an odorless chemical. It is almost insoluble in ethanol and ether. L-Glutamic Acid boiling point is 225 °C, Monosodium Glutamate Melting Point is 450 °F. When it decomposes, it emits sodium oxide and nitrogen fumes. L-Glutamic Acid 5% solution is between 6.7 and 7.2. Monosodium Glutamate (MSG), the most known and used flavor enhancer in the world, is a sodium salt of L-glutamic acid. Glutamate, found in protein-rich foods such as meat, chicken, cheese and some vegetables, is produced naturally in the human body and plays important roles in various organs such as the brain and muscles. L-Glutamic Acid, which strengthens the existing flavor, is an additive that has been used in the industry from the past to the present. Thanks to this feature, L-Glutamic Acid is added to many foods and increases the existing flavor of the food. L-Glutamic Acid has many different uses in the food industry. It is used as a thickener in ready-made foods produced in liquid form. It is also used as an additive in bakery products, and it is used in animal feed due to its effects such as bone growth, egg shell hardness, mineral absorption, and reducing body fat. L-Glutamic Acid is also used as a flavoring ingredient in ready-made foods such as sausages, hamburgers, instant soups, crackers, broth tablets, meatball mixtures, and salad dressings. In addition, glutamic acid is applied in various processes and studies in the medical and health fields. It has the opportunity to be used in medical applications due to its properties such as helping patients with osteoporosis conditions, increasing calcium absorption, and being a biologically compatible carrier in the treatment of cancer drugs. In the field of cosmetics, it finds a place in shampoos, personal care and special care creams as it reduces skin wrinkles and improves skin care quality. Pyrrolidone carboxylic acid (PCA), synthesized from glutamic acid, is used in the cosmetic industry as a natural moisturizer. It can be used in water treatment processes to clean heavy metals and remove radionuclide groups. In the fertilizer industry, it is a very good anti-pathogenic agent with its inhibitory function. It is extra suitable with its high water absorption capacity and is used especially in liquid and special fertilizer production.

In order to determine the food additive production potential of the isolated microorganisms, they are incubated at 37 °C and 48 hours in orbital shaking incubators and shaking water baths under specified environmental conditions and times. The incubated microorganisms are stored at +4 0C in order to stop reproduction until the analyzes to be performed in the next stages. At the next stage of the invention; Process characterization of microorganisms, whose genotypic identification has been made, begins. At this stage, microorganisms are cultured on the media in an orbital shaking incubator and a shaking water bath, and then the optimum food additive production is determined by a spectrophotometer. Then, controlled experiments are carried out with different combinations of the chemicals mentioned above to determine the mixture in which the relevant microorganism is maximum. After incubation, the L-Glutamic Acid concentration produced by microorganism cultures using spectrophotometric methods is determined using the acidic ninhydrin method. For this purpose, 200 uL sample from the incubated supernatants was placed into a sterile microcentrifuge tube. Then, 550 µL of ninhydrin solution was added to the microcentrifuge tube and kept in a water bath at 60 DC for 1 hour. After the samples taken from the water bath came to room temperature, 1600 pL of glacial acetic acid was added. UV absorbance measurement of the samples, whose preliminary preparations were completed with the acidic ninhydrin method, was made with a spectrophotometer at a wavelength of 470 nm. At the end of the spectrophotometric analysis, genotypic characterization of the microorganism with the highest potential for producing the food additive L-Glutamic Acid is performed. For this purpose, sequencing of 168 rRNAs of the microorganism with the SANGER method is used. As a result of sequence analysis, it was determined that the microorganism with the highest production was Bacillus type bacteria, and the resulting strain was Stenotrophomonas sp. It was named strain CG2 and 168 rRNA sequences of this strain were recorded in the NCBI gene bank with the code OM341624. At another stage of the invention; The pH, temperature, speed and incubation time values at which the food additive production is maximum for the microorganisms whose optimum medium contents are determined are determined. Microorganisms are incubated in prepared nutrient media under environmental conditions and times determined according to the literature, and after incubation, L-Glutamic Acid production rates are determined using the acidic ninhydrin method with Spectrophotometry. Application of the Invention to Industry: L-Glutamic Acid is produced completely in accordance with halal standards with microorganisms in the above-mentioned medium, environmental conditions and times. With the increasing awareness of halal standards in the Islamic geography, research on the production of food additives suitable for Islamic conditions has also gained momentum. The invention enables the production of L-Glutamic Acid, one of the food additives, under halal standards and its use in the food industry. It is clear that a person skilled in the art can demonstrate the innovation set forth in the invention by using similar structures and/or apply this structure to other areas with similar purposes used in the relevant technique. Therefore, it is obvious that such structures will lack the criteria of innovation and especially surpassing the known state of the technology. TR TR TR TR
