ANALYSIS OF BACTERIA GROWTH Abstract Bacteria can be found everywhere on the earth. Bacteria are single-celled organisms that lack a nucleus‚ mitochondria‚ and chloroplasts and are surrounded by a cell wall containing a peptidoglycan layer. They are defined by their small size and wide range of shapes. In this experiment we separated organisms in a mixed culture to study the colony morphology and physical characteristics and determine which organism was present in higher numbers‚ as determined

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

Ben Grygiel Professor Sides ENG-101-D260 1 September 2013 “Observing the Ordinary” Why do people tend to feel attached to “things”? This is a very good question that needs some thought behind it to give you a clear understanding why people feel this way. It’s in our nature to show emotions. If you think about it‚ everything we do in our lives we are showing some sort of emotion or feelings. When I think of people being attached to “things” the first thing that pops in my head is little kids

Introduction- This lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size‚ shape‚ color‚ consistency‚ and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies‚ but spans the entire community of life

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

Cheese: A Home to Bacteria “Cheese is just a means of controlled spoilage‚” said Steve Jenkins‚ a Master Cheesemonger at Fairway Market. (Cheese) Bacteria‚ or starter cultures‚ control the flavor‚ hardness‚ type‚ and many more aspects of cheese. The two main strands of bacteria involved in cheese making are Lactococcus and Lactobacillus‚ which ferment sugars found in the milk. Humans have learned to manipulate bacteria and the fermentation process to produce different types of cheese such as Swiss

a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are unicellular microorganisms‚ with variable shapes and nutritional needs. They lack a distinct nucleus and occur singly or in chains or clusters and form distinct colonies. Bacteria are classified on the basis of many

Virus and Bacteria Virus - A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria - Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large
