against tested bacteria and fungus and more commonly used antibiotics were used in comparison to propolis samples. The second method was employed by measuring Minimal Inhibitory Concentration & Minimal Bactericidal; Fungicidal Concentrations (MIC‚ MBC & MFC) using two fold dilution method for propolis extracts and ethanol 70% as a solvent control in serial concentrations. The Results exhibited that propolis is more efficient than some antibiotic discs. The most sensitive bacteria against (EEP)

To deduce if UV Radiation induced a mutation in the DNA of Serratia Marcescens and prevented the production of the red pigment called Prodigiosin. Hypothesis: Maybe the disappearance of red color in Serratia Marcescens is caused by the UV light which induces mutations in its DNA and is known as a common mutagen. Prediction: If UV light mutates the DNA of Serratia Marcescens then the red pigment colonies of the bacteria will no longer be produced. Independent Variable: Ultra Violet Radiation

Identification of Bacillus subtilis and Serratia marcescens Through a Battery of Tests and Plates Introduction: The purpose of this experiment was to use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to be identified; the basic

Practical 9: Examination of Bacterial Plates Objective: 1. To examine bacteria pigmentation‚ colony‚ margin characteristics‚ elevation properties‚ broth characteristics and agar stroke properties. 2. To examine bacteria growth characteristics on different culture media. Introduction: Bacterial species can sometimes be identified on the basis of how they appear on or in the different media. The pigmentation‚ size and shape of bacterial colonies as they grow on and in agar plates can

Unknown #1 Vomit Serratia marcescens & Bacillus cereus Biol 251 Microbiology 5/14/2009 Introduction The purpose of this study is to differentiate and identify two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The
