So that's why that such factors has the, which can alter the pH. On other hand some time when the organism produce some product that have an acidic nature or they have alkaline nature. then they can tend to change the pH of the medium. Sometimes pH, we have to regulate the pH just for the sake of some desired product. In case of calcium gluconate. In case of sodium gluconate we have to keep the pH at 7. So because when there will be automatic run and there is no pH control, is a gradual changes in the pH to the acidic side. So, the pH control system is very critical. Normally, when we want to control the pH, we have to use either the alkali agent or the acid agent. This alkyl and then acid- then that's how much is the total system should b controlled. अंकि आप यह थःट हम श़़ा กब श़ पद reviews , लवकण कोंगट क्चव Meeral जोच्वना दाछ यह क्च्वन वरखड गया वरन ही था या आप ब सच्बि वरखड हर शाथ वर शे ऒ्द Wake तनीट रन को Couva. उसह pack च oral , नहीं नरा теперь आत केर, चोज आप हूद on  vorbere H  toolbar మాథతారారిరాన్తి పిలవరి కపరయారింది నిఎది ఇదిరికి మారాిక౿ సిపికిఁలా. ఉ఑ిమది మాపికిదిటాత పింిటిలకిని. వరరికి కమట౤ిదిల౿ నికీ చాడామిబిధిలాలుతీటారండిరియ నానైండికీటినికైజిిలినై నైయారిలిఱిము . तो क्यो अच is more expensive than any अच, तो वन is the type of the compound and other is the rate of that. तो वी have to be very careful. तो here you can see that hydrochloric acid should never be used as it is aggressive even to the stainless steel. तो sulfuric acid in a concentrated should not be between 10% to 10% and 80% as between this range of silver cases is more aggressive. तो वी these are very strong compounds we should be very careful while selecting our neutralizing agent. तो for laboratory fermenters the pristel pump is used to add the pH adjusting agent and then that is linked with the different kind of the tubing. तो mostly the silicon tubing is used so the silicon tube will decay in the presence of high alkali concentration तो when we sterilize that material in a high temperature then the silicon tubing have a restricted life. तो alternatively we can have a choice of using the taigon and neuroprene tubing. तो the taigon is not autoclave but can be sterilized by passing the sodium hydroxide through the tubing for about 1 hour. तो the neuroprene is autoclave but is not transparent so that is why the taigon or the silicon tubing is mostly used for the addition of the neutralizing agent. तो for fermentation that produce a large amount of acids for example, electric acid fermentation is using media then there is some specific molarity is needed. तो alkali that have four molars and above is preferred. तो this will prevent the dilution of the medium because when we use the diluted neutralizing agent that can raise the volume of the medium that can affect the kinetic parameters. तो we should use a specific strength and the concentration of acids or the alkali agents which we use as a neutralizing agent. तो the
