The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Botulism Botulism is a bacterial disease most often linked to un-sterile canned foods. It can be rather serious‚ as it has the potential to paralyze the respiratory system and thus cause death. The bacterium is named Clostridium Botulinum‚ it is a gram-positive and anaerobic pathogen. The morphology consists of rod shaped spores. The toxin is widely used in cosmetic injections‚ also known as Botox‚ to decrease wrinkles in the skin. Though Botulism is mainly linked to canned foods

Mini-Lab Report Objectives: There were two major goals of the “Observing Bacteria and Blood” experiment. The first was to establish a familiarity with the proper techniques for using a microscope. The experiment focused on both the basic components of a microscope (i.e. how to adjust the knobs and levers for the desired result) as well as how do decide the proper objective to use for observing a specimen. The second goal major goal of this experiment was to practice observing live specimens

The Growth of Bacteria Influenced by Different Antibiotics Introduction: Plants are made up of three basic kinds of tissue that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter

This book is a nonfiction academic monograph. Since she discusses other people’s research‚ she synthesizes other research works. She discusses more than she presents -- it is not a dry list of data throughout the book. Motive of author: Radden has a desire to compare what lies behind the differences in people’s behaviors (the way we process and see things). There are all different kinds of delusions. She wants to explore the social implications and domains of research of delusions. There are

(APC) and total coliform count of supplied yogurt sample. Purpose: To determine the aerobic plate count and total coliform count of the supplied yogurt sample. Principle: Yogurt squeezed or extracted from milks are more or less acidic‚ depending on the product‚ the pH generally ranges from about 2.4-4.2 and contain sugar (4.7g)‚ fat (3.3g)‚ carbohydrates (4.7g)‚ and proteins (3.3g). Although molds can and do grow on the surface of yogurt if the yogurt are exposed to air‚ the high moisture contents

Case Study – Babybelle While observing the judge’s legal reasoning in this particular case‚ I could say that ”Ratio decidendi” depends on the current facts emphasized in the case and that “Obiter dicta’s” concept presents conclusions based on hypothetical situations. - The major legal issues The legal issues in this particular case are relied on the ASIC Act where a person becomes automatically disqualified from managing a corporation if the person is convicted of an offence that “involves dishonesty”

An observation takes place when practitioners watch the children who are within their care and take notes of what they see or hear. Observations help identify individual children’s needs in order for them to be met. Taking regular observations of children help practitioners discover children’s interests as well as new skills and abilities. Similarly‚ observations give professionals the chance to monitor children’s progress and plan next steps to further children’s development. Main reasons for observation:
