Bacillus cereus

Materials and method Microorganisms are classified in to the three domains of life. The organism that is predominately found in our environment is bacteria closely followed by archaea and eukaryote. Although, microorganism might seem similar, they are different interims of their structures, biochemical composition, and the habitat they adopt. Conducting an extensive test on microorganism has many benefits. We can protect our self’s from different types of infectious disease. In the unknown…

It is conspicuous from various studies that the metal based nanoparticles is found to be an effective antimicrobial agent against several common pathogenic microorganisms.(Nanoparticles and potential apps, Biomedical applications,Antimicrobial activities of silver nanoparticles, Green synthesis, A review on plants extract mediated, Antimicrobial Properties).It is multidisciplinary area where in nanotechnology has led to major developments in health and medicine due to the integration the…

Results: Dichotomous key Gram Stain: After performing the gram stain, our unknown organism appeared to be pink indicating that it is gram negative and that the morphology is rod shape or bacillus. This indicate that this peptidoglycan cell wall is much thinner compared to the control we observed from bacillus cereus. Gelatin Hydrolysis test: The purpose of the gelatin hydrolysis test was to determine if our organism had the enzyme gelatinase, to hydrolyze gelatin in the gelatin agar plate…

Toxic shock syndrome (TSS) is a rare but damaging acute illness that affects children with burn injuries. The aim of this study, using an exploratory sequential mixed method methodology, is to develop an early warning prediction tool that can predict toxic shock. The qualitative phase of the study will use investigative interviews and case study to collect data of the childs pre-injury health which will be analysed using content analysis to develop a questionnaire that will be used within the…

Isolated Colonies and Soil Samples A. Purification of Serratia marcescens and Staphylococcus epidermis The objective was to grow isolated colonies on a nutrient agar medium (NA). Many microorganisms found in soil are able to grow on this medium. Since there are many organisms that are found in the soil, only a few of this organisms are adapted to live in this specific medium obtained. The NA plate is the first way to isolate microorganisms because the organisms that will be left on the plate…

All bacteria are lacking of a membrane-bound nucleus and other membrane bound organelles, classifying them as prokaryotes. In the six-kingdom system used by the United States, all bacteria fall into the taxonomic kingdom of either archaebacteria or eubacteria. Bacteria are all unicellular and microscopic regardless of which kingdom they are grouped in. In general, archaebacteria are thought to resemble the first living bacteria on earth and are normally grouped by the climate in which they…

INTRODUCTION : Ghee is a class of clarified butter that originated in South Asia and is commonly used in South Asian (Indian, Bangladeshi, Nepali, Sri Lankan, and Pakistani) cuisine and ritual. Ghee is a type of clarified butter that is prepared by boiling butter and removing the residue. Spices can be added for flavor. Ghee has a long shelf-life and needs no refrigeration if kept in an airtight container to prevent oxidation. The texture, color and taste of ghee depends on the…

Term Paper: The Effects of Foodborne Illness of Escherichia coli in Leafy Greens Introduction Food is a necessary and many times pleasurable part of everyday life. Bacteria are also a necessary part of everyday life, but not often thought of as pleasurable. Humans are made up of approximately 103 cells, and harbor about 104 bacteria cells (Davis 1996). It is shocking that the human body hosts more bacteria cells than its own body composition. Fortunately, most of these bacteria that live on…

1. INTRODUCTION Electrochemical Impedance Spectroscopy is an effective method of analyzing the intricate electrical resistance of a process and it is sensitive to surface phenomena and changes in the bulk properties. Thus it plays a major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of…

Molds are multi- or unicellular while yeasts are unicellular in structure. Molds grow in the form of tangled mass called the mycelium which is composed of filamentous hyphae while yeasts are spherical or oval-shaped. Molds are colourful while yeast are colourless. Molds can reproduce through small spores sexually or asexually while yeast reproduce asexually by budding or binary fission through mitosis in which a nucleus is divided into two or more nuclei. Mould can grow on food with low pH…
