Abstract:
The use of cotton plug as closure of a bacterial culture flask had been reported to have many disadvantages such as inhibitory nature of cotton to certain microbes, chances of contamination during handling and accumulation of used cotton as biological waste. To overcome the disadvantages of cotton plugs, we have developed a new method of capping bacterial culture flasks. In the present study, three sets of experiments were conducted, one was to find out the efficiency of bacterial growth in culture flasks closed by either glass caps or cotton plugs and the second set was to find out the chances of getting contamination of sterile broth closed by either glass caps or cotton plugs and the third set was to find out the evaporation of water in conical flasks closed by glass caps or cotton plug. The results showed that the bacterial cultures closed by glass caps showed better growth with less chance of contamination and evaporation of the culture media. By this method, the bacterial culture work is made very simpler than using cotton plug.
