Identification of A Mixed Culture Unknown An experiment such as this one serves the purpose of allowing us‚ the students‚ to apply what we already know about any organism and any laboratory procedure to the difficult task at hand. It is possible to identify a mixed culture by running familiar experiments on the unknown bacteria and taking information already known about specific bacteria and applying it to the results. This helps to slowly eliminate any bacteria that do not correspond with the

3-2-3-1-Conventional Culture Method (Marks 1972): The infected lesions of the tuberculin positive reactors were collected and placed in to a sterile mortar containing sterile sand. The fat was removed and the suspected parts were cut into minute pieces. Then 2 ml of distilled water added to the mixture‚ homogenized and crushed well until the suspension was obtained. Then 2 ml of H2So4 acid 4% added to the mixture then incubated the mixture at 37 0C for 1/2 h. The mixture was diluted with

mossambicus has a low oxygen demand and can survive at low oxygen levels (1-2mg/l). Riche and Garling (2003) reported that dissolved oxygen levels should be maintained above 4.9 mg/l for best growth. The water quality tolerance limit of O.mossambicus for nitrite is 0-0.6 mg/l while for ammonia‚ it is 0-0.12mg/l (Robert‚ 1997). This falls within the range of values that were obtained throughout the whole experiment (Table 10). 5.2. Proximate composition and amino acid analyses

Jana Carroll Mark Shealy English Composition 1 27 October 2013 Going Organic Grocery shopping in today’s society can be extremely confusing for most consumers; I have often pondered over which product to feed my children and if organic food is actually better than processed food. Although I have heard many people say organic food is a gimmick to get more of today’s consumer’s money‚ or that they just can not afford it; I argue that eating organic is a more healthy choice. “Organic food consumption

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table‚ viz. Lithium (Li)‚ Sodium (Na)‚ Potassium (K)‚ Rubidium (Rb)‚ Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell‚ which is just outside an inert

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in
