Description
A FLUID MICROORGANISM MIXTURE WITH AN EXTENDED SHELF LIFE FOR REMOVING PTA COMPONENTS FROM THE WASTE WATER AND PRODUCTION METHOD THEREOF
The relevant technical field of the invention:
The invention is related to the formation of bacterial culture products in fluid form which has high biodegradation efficiency, is environmentally friendly, in the presence of an appropriate substrate relative to the hydrocarbon types in order to be used in biological treatment applications of various petrochemical oil and refinery plants.
The invention is particularly related to production of adapted bacterial cultures in fluid form and with high efficiency and performance by means of reproduction thereof in the presence of appropriate substrate in reactor systems, which will be used in the treatment of pure terephthalic acid (PTA) waste waters with a hard-to-degrade xenobiotic characteristic.
State of the art:
Upon the emergence of industrial, agricultural, mining, pharmaceutical etc. pollutants; new applications for eliminating these pollutants are required. Accordingly, in the elimination of these pollutants, Environmental Biotechnology applications which use microorganisms with microbial biotechnology potential are developed. Therefore, treatment of the surface and underground water, soil improvement, industrial waste water treatment, gas purification is developed.
The microorganisms are able to degrade the hydrocarbons which are both naturally formed and are included in the structure of the environmental pollutants. It is found in the studies conducted so far that the microorganisms are able to degrade various pollutants which can be found in the structure of phenol, benzoate, eicosane, 2,4- dichlorofenoxyacetic acid (2,4-D), polyaromatic hydrocarbons (PAH), xenobiotic hydrocarbons and crude oil under appropriate conditions.
The patent document No“KR0000034035” is analyzed as a result of the preliminary search made about the state of the art. In the abstract section of the invention subject to this application, there are the following information,“Providing the bio-reproduction of microbial components in the soil which is contaminated by oil by means of the optimum fermentation of the hydrocarbon degrading microorganisms which isolates thereof from the oil and the contaminated soil”. Nevertheless, since the present invention only studies on the soil contaminated by oil, it may be limited in terms of the contaminated area and type on which it is effective.
The patent document No.’’US6365397 (B1 )” is analyzed as a result of the preliminary search made about the state of the art. In the abstract section of the invention subject to this application, it states that“The biologically pure bacterial species obtained with enrichment of the bacterial culture isolated from the active sludge which are taken for the treatment of the wastewater in a chemical plant are reduced to t-butyl alcohol (TBA) after its ether bond in methyl t-butyl ether (MTBE) is broken then to CO2 during their respiration with oxygen”. The current system enables the degradation of the alkyl-alkyl ethers, particularly methyl t-butyl which are used as octane enhancers in unleaded gas mixtures with low volatility. Therefore, it has a main disadvantage that the components on which the isolated bacterial culture has an effect are merely alkyl-alkyl ethers.
In the above listed inventions, when we consider the state of the art, it is clearly seen that the activation (effectiveness, productivity) of the product or methods aimed for wastewater treatment are limited in relation with the contamination type and components on which they have impact. Accordingly, an improvement in the relevant technical field is required based on the insufficiency of the current solutions on the highly efficient biological treatment of PTA wastewater.
Aim of the Invention:
The most important aim of the invention is to provide a fluid bacterial culture which is adaptable for PTA wastewater treatment, has high biodegradation efficiency and transform thereof into a stabilized bacterial culture with extended shelf life by means of reproduction.
Another important aim of the invention is to adapt them easily to the system on which they have effect and thus to provide the quick efficiency of the bacterial cultures.
Another important aim of the invention is to reduce costs for said process by means of the high biodegradation efficiency and system adaptation (that the production has low cost)

Description of the Invention:
The invention is particularly related to production of adapted bacterial cultures in fluid form and with high efficiency and performance by means of reproduction thereof in the presence of appropriate substrate in reactor systems, which will be used in the treatment of pure terephthalic acid PTA waste waters with a hard-to-degrade xenobiotic characteristic.
The stabilized bacterial culture in fluid form with extended shelf life which has high biodegradation efficiency mainly consists of; bacterial mixture isolated from the active sludge, distilled water and various nitrate salts.
In the content of the specific bacterial mixture isolated from the active sludge, at least one of the following families exist; Pseudomonadaceae, Comamonadaceae. Pseudomonadaceae Bacteria is a family within the domain and bacteria species such as Azomonas, Azomonotrichon, Azorhizophilus, Azotobacter, Cellvibrio, Mesophilobacter, Pseudomonas, Rhizobacter, Rugamonas, and Serpens etc. are included within this family. Comamonadaceae is a wide and various bacterial family. Bacteria species such as Acidovorax, Albidiferax, Alicycliphilus, Brachymonas, Caenimonas, Comamonas, Curvibacter, Delftia, Diaphorobacter, Extensimonas, Giesbergeria, Hydrogenophaga, Hylemonella etc. are included within this family. Pseudomonadaceae, Comamonadaceae families are isolated from the current
wastewater treatment system which is their natural habitats, thus their adaptation to the system is very easy and rapid.
Nitrogen ions in the nitrate salts content are converted to nitrogen gas by a number of microorganisms to produce energy. This event is called denitrification. Denitrification bacteria obtain the required energy for their growth under anoxic conditions in this manner and therefore their viability and amount, thus their shelf life is protected. It is known that numerous types of bacteria such as Pseudomonas stutzeri etc. make denitrification by using nitrate or nitrite as the main electron for anaerobic respiration. The nitrate salts are the salts of nitric acid and among its types there is sodium nitrate, potassium nitrate, ammonium nitrate.
The distilled water is obtained by means of boiling the normal tap water at a predetermined temperature and separating the pathogenic substances therein and thus re-condensing thereof and forming water again.
In order to obtain the product, the following method is followed.
The components and the amounts of reproduced bacteria isolates are shown in Table 1 . Table 1 : A table showing the components and amounts of the reproduced bacteria isolates
In relation with the product content of the main aspect of the invention, the components included in the above table are used, the final product stabilized
bacterial culture in fluid form is obtained produced by means of the below described method. Production of bacterial culture in fluid form consists of the following process steps,
• Isolating bacterial mixtures of Pseudomonadaceae, Comamonadaceae families in the product mixture by ratio of 2-20%
• Forming the bacteria-feeding growth medium by means of adding 0,1 -2% ratio of sodium nitrate into the distilled water in a ratio of 78-97,9%
• After the bacteria-feeding growth medium is formed, producing bacterial culture in fluid form by adding isolated bacterial mixture between 2-20% ratio to the feeding growth medium at 27°C temperature.
The shelf life studies of the product which is obtained after said process steps were made at 20-35°C temperature, acid degree of pH 6-8. The shelf life studies were started with at least 1010 kob/ml microorganism initial microorganism and it is detected that at the end of 6 moths the number was 104-108 kob/ml. Accordingly, at least month 6 shelf life is determined with optimum temperature of 20-35°C, and pH 6-8. The graph showing the change in the number of the living microorganisms according to months in shelf life studies is shown in Figure 1 .
Different storage conditions are determined in a manner such that the degradation of bacterial cultures and viability efficiency is optimum by means of making pre-tests in obtaining fluid product with high bio-degradation for PTA wastewater subject to the invention. The efficiency of these microorganisms produced in this context in the fractionation of chemicals which constitutes PTA wastewater such as terephthalic acid (TA), 4-carboxybenzaldehyde (4-CBA) and paratoluic acid (P-tol) etc. at the end of the shelf life is evaluated.
It is aimed to use bacterial culture in powder form subject to the invention in biological treatment systems, petrol industry and treatment of pure terephthalic acid (PTA) wastewater.
Optimum rates pertaining to the product content were determined by making preliminary tests in the study. Therefore, these percentage rates are important in terms of bacterial viability concentration of the final product and in case there are changes in
the rates, when we consider the bacterial viability, this can lead to unexpected decreases in application of both final product and in environmental system. In this case, there will be no improvement in the performance of the treatment process which is the final target.
