FOOD TECHNOLOGY

Detailed explanation-1: -The Isolation of Microorganism From Air is performed by using the settle-plate technique. In this method a suitable medium is poured over a sterile petri dish and then allow it to slidify. After that the plate is exposed to the open air for a few minutes.

Detailed explanation-2: -Ventilation and air movement can reduce bacterial growth because moisture evaporation increases significantly as air movement increases, which dries the surfaces of substrates and inhibits bacterial growth. The evaporative heat transfer coefficient increases exponentially as the air movement increases [23].

Detailed explanation-3: -Cetrimide Agar Base is a culture medium used to selectively isolate and identify Pseudomonas aeruginosa. Cetrimide is a quaternary ammonium that inhibits a large number of bacteria, including those of the genus Pseudomonas, other than Pseudomonas aeruginosa [10].
