water samples that were collected from the Pacific coast of Japan (unpublished results). Among the isolates‚ a novel‚ highly selective astaxanthin-producing marine bacterium‚ labeled strain (N-5)‚ was isolated based on its ability to produce orange pigment on NA plate after 2 days of cultivation at 30 °C. Strain N-5 formed colonies that were medium in size (1.0−2.0 mm in diameter)‚ circular‚ shiny‚ and orange (Figure 1B). Unless otherwise specified‚ all characteristics described hereafter are those

with the addition of light: H2O + ADP + inorganic phosphate + NADP+ ¨ 1/2O2 + ATP + NADPH + H. Light is a necessary input for photosynthesis to take place. Light ’s electromagnetic radiation carried in photons are absorbed by the photosynthetic pigments in plants. These photons can cause electron excitation to a higher energy level‚ which can be added to NADP+ form NADPH or the excited electrons can also be passed down an electron transport chain producing ATP. These processes occur in

Growing up with a parent in the medical profession‚ I have seen at first-hand the diverse life of a doctor with its challenges and demands. Medicine is a career constantly changing and developing; as a course I will continue to utilise all I learn. My juvenile arthritis shows me the human body is complex and problems can so easily arise. A condition affects not only the patient‚ but the family and I can appreciate how rewarding being a doctor‚ with the capacity to help those in need‚ would be. Shadowing

TRACE EVIDENCE AS AN IMPORTANT TOOL UNDER FORENSIC SCIENCE Introduction Edmond Locard‚ founder of the Institute of Criminalistics at the University of Lyon‚ France‚ developed what has become known as Locard’s Exchange Principle. This states that “every contact leaves a trace”‚ implying that a criminal will leave trace and take away trace evidence when at a crime scene. Trace evidence often refers to minute samples of a substance‚ particularly fibres‚ hairs‚ glass fragments and paint chips. Crime

Experiment 1: Quantitative assessment of Some Cellular Constituents Summary: Euglena gracilis are unicellular organisms in the Protist Kingdom. They are known to have both plant and animal characteristics. Although‚ Euglena cells contain a variety of cellular constituents‚ their cellular constituents should be presented in equal ratio. The objective of this experiment is to determine Euglena’s cellular components in cells and then to establish their cellular constituents by comparing the experimental

Analgesic Drugs Introduction: The purpose of this lab was to determine the composition of four different over-the-counter drugs (Anacin‚ Bufferin‚ Excedrin‚ and Tylenol). These compositions were determined by using the method of thin-layer chromatography (TLC) of the four over-the-counter drugs‚ which were then compared to four different components of drugs (acetaminophen‚ aspirin‚ caffeine‚ and salicylamide).
