Growth medium Essays

The creation of the master plate was made up of specially selected bacteria from both experiment 3.2 and 4.1, the goal was to achieve a diverse selection of bacteria to observe closely at its texture, color, shaper, and margins. When selecting specific bacteria, I looked for the best combination of variation and choosing across all five of my plates for both agars. Through using morphological observation I was able to determine different bacteria such as colonies that are irregular and circular continuing

Materials and methods Isolation and identification of Bacillus thuringiensis Bacillus thuringiensis was isolated from raw milk (Taif, KSA) on nutrient agar at 37oC for overnight. The supernatant of the bacterial isolate was screened for synthesis of AgNPs. The bacterial isolate was morphologically and biochemically characterized according to Bergy’s Manual of Systemic Bacteriology[21]. Also, this bacterial isolate was further identified by 16S rRNA sequencing. The culture was maintained on a nutrient

Chapter 5 Bacterial Growth Micro-organisms such as bacteria can be grown in the laboratory if essential components required for their survival are present. The cat of growing bacteria in the lab is referred to as culture and the environment on to which the bacteria is grown is called culture medium. The essential ingredients required for bacterial growth include: o Carbon source o Nitrogen o Metal irons o Presence or absence of Oxygen o Optimal temperature o Optima pH o Moisture Forms of Media

Effect of different physical conditions on nitrogen fixing bacteria from rhizosphere Hypothesis: Rhizospheric Nitrogen fixing bacteria show optimal growth at PH: 6-7, Temperature: 30 °C and Salinity level: 0.005 – 0.010M NaCl INTRODUCTION: There is a huge bacterial diversity in rhizospheric soil. Gram-negative, non-sporulating baccilli which respond to root exudates are predominant in the rhizosphere (Pseudomonas, Agrobacterium). While Gram-positive

In conclusion, a few of the hypotheses stated in the introduction were proven correct but most were not. In the beginning, it was thought that in three plates the bacteria could be separated, however, it actually took four plates to separate the bacteria. It was confirmed that both bacteria are gram positive. However, along with this one of my bacteria was not Staphylococcus. One being Bacillus was confirmed and actually both ended up being Bacillus species. It was thought that one bacteria

The experiment began by obtaining a sterile cotton swab and a petri dish and searching for a collection site in the Biology Department that would have bacteria. The unknown sample was collected at a recycling bin in Biology Building East. We swabbed the recycling bin using the sterile cotton swab and gently streaked the swab across the surface of the petri dish and immediately covered it with the lid. The petri dish was then placed in an incubator at 37C for two days. Two other petri dishes were

capable of producing a pigment which ranges in color from dark red to pale pink, depending on the age of the colonies. This meant that all I needed to do in order to distinguish my bacteria was to determine the effects of temperature of my microbial growth. This lead me to perform a streak plate which was incubated at body temperature, 25 degrees celsius. After incubation, my organism appeared as a pink pigment, in conclusion, it was presumtively Serratia marcescens. S. marcescens is capable of thriving

Judith and her Maidservant with the Head of Holofernes Judith and her Maidservant with the Head of Holofernes, by Orazio Gentileschi, is a 17th-century oil painting located in the Wadsworth Museum of Art. The painting depicts the moment after the biblical heroine, Judith, kills an invading Assyrian general, Holofernes, to save the city of Bethulia. Judith agrees to dine with Holofernes in the privacy of his tent and after taking advantage of his drunkenness she beheads him with his own

Formulating a definition of effective teaching, Goe, Bell and Little (2008) evaluated various discussions in the recent literature as well as in policy documents, standards and reports. They concluded that effective teachers have high expectations for all students and help students learn; they contribute to positive academic, attitudinal, and social outcomes for all students; they use resources to plan and structure engaging learning opportunities; they contribute to the development of classrooms

I simply wrapped up The Oyster Princess, a beautiful Lubitsch film that by one means or another blends the two altogether different ingredients of anarchy and sophistication with lovely results. What truly got my attention was the scene of the film, where it is asserted that the film is a metaphor for American consumerism. As per my seeing; there are various understandings of the film through investigation, utilizing the four cinematic methods: Mise-en-scène, altering, cinematography, and sound.

Rohan Trivedi Neeraj Prakash English 103- AS (17) 20 March 2018 The Value of Literature Literature is a body of written works, wherein the name is often applied to imaginative works of poetry and prose distinguished by the intentions of the authors. Literature is classified according to variety of systems, including language, national origin, history, the period, the genre and the main subject. It represents human expression, we read literature because it is inspiring, and it embrace the incredible

How did we become a human? That is the question that is trying to be solved. It is mental to think about how the humans are a prolonged and more developed member of the great ape family. We have evolved into a more mature and sophisticated species that yearns to share our personal stories. Jonathon's Gottschall's preface, The Storytelling Animal, starts with scientist believing if monkeys were left in a room with a computer they would eventually write hamlet word for word. The human mind is obsessed

Whirlpool Galaxy Galaxy Profile: • Designation: M51, SA(s)bc pec • Type: Spiral • Distance from Milky Way: ~25 million light-years • Diameter: about 75 thousand light-years across • Mass: ~160 billion suns • Number of Stars: > 100 billion\ Facts about the Whirlpool Galaxy: The Whirlpool Galaxy was first discovered in 1773 by Charles Messier, who was charting the skies looking for objects that might be confused with comets. In 1845, astronomer William Parsons observed the galaxy pair with his telescope

The process of stellar evolution begins with the formation of the star. It starts as a cloud of gas and dust. This is critical because the chemicals and amount of stuff in the cloud will determine the entire life of the star it’ s creating. The density will increase because of its gravity and its spin will become more dramatic. Then little tornados (well tornado like things) will form in the cloud. These will eventually become star systems. All the material falling onto the tornado causes it to start

The Great Orion Nebula holds the key how the Sun and all the stars in the galaxy was born. The Milky Way is filled with billions of stars in every direction. From Earth the naked eye can see large dark patches in the sky. The clouds of dust cast shadows from the back of the stars, where the stars are shining their light through lower dust clouds blocked by light. What astronomers found with the tgas is that it can sometimes glow; the bright glowing clouds are called “Nebulas”. Each is unique in its

Stars are hot bodies of glowing gas that start their life in Nebulae. They vary in size, mass and temperature, ranging from 450x smaller to over 1000x larger than that of the Sun. Now, the color of a star is determined by its temperature, the hottest stars are blue and the coolest stars are red. The energy produced by the star is by nuclear fusion in the star’s core. The brightness is measured in magnitude, the brighter the star the lower the magnitude goes down. They are two types of stars, Low

annual proportion of on-time flights to total flights, and customer satisfaction survey. The annual number of new customers is being measured because an increase in the number of customers can give the company an idea about their future and potential growth in the market. This also gives an idea about the customer satisfaction. The annual proportion of on-time flights to total flights is the basic indicator for airlines. Even if the company has a low-fare image, if their flights are late, customers still

The stars shine bright on the vast stage of the galaxy. The awe-inspiring constellations have shifted and torn, casting stars light-years from their position, giving each a dancing partner. Each star compliments their companion and each shine brighter than they could have alone. The stars twinkle softly and watch me watching them. I wish to teach them, for I have lived a long, prosperous life and I know I can teach them so much. I sit in a swirling spiral galaxy of amber and allow the grains to whisper

Recurring Slope Lineae (RSL) describes a phenomenon observed on Mars. RSL are dark, narrow marks that appear on the sides of steeper slopes on the Martian surface. The marks grow longer during the warmer seasons. The elongation of the RSL is more pronounced on slopes that face the equator, as well as slopes that are facing the sun [1]. The current hypothesis as to the origin of the RSL is the transient flow of briny water. Evidence of this was described by McEwan et al (2013). RSL observed on
