Abstract

In the early human thought, the objects or person's names were consistent with his essence, because primitive man thought that the relationship between the name and object or person is not conventional, and the forces of evil can harm him through his name. This vision is not spatially bounded, and there is in all societies and to all of them has been imposed special rules as taboo naming. In Iranian folklore and Shahnameh, we can easily see the following statements: Sometimes the name is same person's essence. This kind of taboo is seen when Rostam speaks about Siavash murderers by Human. Another example of taboo is the choice of two names to escape the magic injury. We can see this kind of taboo in the southern coast of Iran and among Turkmens. In Shahnameh we can see this factor in the story of Ghobad and Shide. The third example of taboo naming is to not say the name in the battlefield. This can be seen in the following two ways in the Shahnameh: 1- to repudiate the name explicitly. 2- to avoid saying the name. The latest example of taboo naming is replacing or renaming, that were used for deceiving spirits and escape from their damage.

Abstract

The ability of bacteria to tolerate low pH is a very important trait to survive in a variety of environments. In the literature, there is a lot of information about the acid tolerance of different bacteria. However, little is known about the acid tolerance of Morganella morganii, the most prolific histamine former in fish and seafood products. Therefore, in the present study, the effect of growth phase, type of acid and medium on the acid tolerance of M. morganii at different pHs were evaluated. To achieve this purpose, cells of M. morganii in exponential or stationary growth phases were exposed to low pHs (3, 4 and 5) adjusted by adding hydrochloric, acetic, lactic, citric or tartaric acids into TSB or PBS for one hour. Survival percentage was obtained by dividing the surviving population by the initial population. In general, results of the present study showed a high acid tolerance of M. morganii. For all the acids tested, the lower the pH of the mediums used, the lower the survival percentage observed. Cells of M. morganii in the stationary phase were more resistant to acidic conditions tested and no significant difference was observed (p<0.05) in the acid tolerance of M. morganii in TSB and PBS at different pHs. In addition, acetic acid and lactic acid showed more antimicrobial effect on both the stationary and exponential phase cells than the other acids use.
