Popular Culture - Essay Example This paper outlines that the popular culture is usually observable in such area including clothing, cooking, sports and recreation and also consumption and entertainment. On recreation we can view golf playing as a popular culture practiced by the rich in the society. Today cultural activities are segregated and there exist restrictions that are formal and also informal. Restrictions apply to those that are not part of that culture and may be tempted to join that culture. This paper highlights that some cultural activities are highly restricted by the laws of the society, an example is beer drinking, beer drinking for example is prohibited in Saudi Arabia and there exist a law that will prosecute those found drinking beer. The drinking of beer therefore is a popular culture among the masses of many societies and this culture is proposed by the mass media through advertisements of these brands, the culture is restricted in some societies like Saudi Arabia formally. There also exist informal restrictions to cultural practices, these informal restrictions are those restrictions that do not exist in writing but are termed as norms in the society, and they do not exist in writing but are termed as rules governing behavior. These informal restrictions include the expected reaction by the society, the society has informal ways in which to discourage behavior example a person doing wrong may be isolated by the society, for example the case where people have tattoos all over their body, this is a popular culture among the young but in some society the making of such decorations on the skin may lead to one being isolated and disowned by the society. This is an informal way in which this popular culture is restricted by this society and it is helpful in restricting such cultures.

Identification of unknown Bacteria Research Paper

Identification of unknown Bacteria - Research Paper Example With regards to the aim of the experiment, which is to identify unknown bacteria from mixed culture #18 using biochemical and morphological test, the two organisms identified had distinct characteristics which were looked for following laboratory tests. Normally, Gram staining is employed to differentiate 2 bacteria groups with different cell wall constituent. The method has the ability to differentiate Gram negative and Gram positive bacteria group; thus the bacterial cells are either colored red or violet. Gram positive bacteria is shown by Violet staining due to a thick layer of peptidoglycan existing   in the cell wall of the bacteria, thus the crystal violet is retained by these cells on a slide. Consequently, Gram negative bacteria is shown by red staining due to a thin layer of peptidoglycan existing in the bacteria cell wall, hence crystal violet is not retained   by bacterial cells. (Winn et al,2006)MacConkey Agar is used to distinguish Gram- negative, lactose-fermenting organisms from organisms that are non-fermentative .It is an inhibitory and differential medium that contains Crystal violets, bile salts, inhibitory agent and neutral red. Neutral red acts as a pH indicator.   Klebsiella pneumoniae bacteria is known to be lactose fermenters hence unknown A while Salmonella Typhimurium bacteria is not lactose fermentor thus unknown B. The orinithine decarboxylase test is important for Enterobacteriaceae differentiation. (MacFaddin, 2000). MR-VP broth for Methyl Red test consists of peptone, phosphate buffer and glucose.
