over 99% of bacteria or antibiotics aren’t discovered. However‚ recently a new antibiotic called teixobactin was discovered. This antibiotic prevents the synthesis of a cell wall by binding to a motif of lipid II and lipid III molecules. The goal of this experiment was to discover how teixobactin interact with bacteria and how it is able to effectively kill pathogens. A device called the iChip was used to discover teixobactin. The iChip helped to isolate and grow uncultured bacteria. Multiple iChips

1. The Native Americans were very practical people. They would use the nature for their source of survival. They used the sky as their calendar and they relied on crops for their food supply.The Natives were warriors and they had cities‚ towns and villages. Not only did they have all these but they worshiped items instead of a god. The Europeans had an advanced culture compared to the Native Americans. They had established churches and a main religion. They also had trading systems as well as people

Contrary to the average human‚ extremophiles love the extreme‚ preferring seemingly uninhabitable environments to resource rich habitats. These archaea are the toughest out there‚ and are found thriving in deep-sea thermal vents and sub-glacial lakes. A few of the outlandish environmental niches extremophiles have adapted to are high/low temperatures‚ pH extremes‚ the absence and excess of oxygen‚ and high salinity. While all these environments seem very extreme to humans‚ several extremophiles

Alcohol is enjoyed by many people during social occasions‚ but for others addiction to alcohol or alcohol-related illnesses can be a serious health issue. • HYDRATION Alcohol depresses the production of antidiuretic hormone (ADH)‚ which helps keep you hydrated. Dehydration can lead to electrolyte imbalances (characterized by nausea‚ dizziness and diarrhea) and headaches. • BREASTS As little as one alcoholic drink a day can increase the risk of breast cancer‚ according to a 2009 study in the Journal

Introduction The purpose of this experiment is to see how much bacteria can and will grow in common places in a typical high school. Common places can mean many things‚ including anything from water fountain spouts to computer keyboards. Such objects can hold up to 2‚700‚000 colony forming units per square inch (or CFU/in sq)(NSF). A colony forming unit is the unit used to find an estimate of the number of cells of a bacteria. This unit of measurement is commonly utilized in the subject of microbiology

offspring; also the level of classification below genus and above sub-species. POPULATION: a group of organisms of the same species that live in a specific geographical area and interbreed. COMMUNITY: a group of various species that live in the same habitat and interact with each other. HABITAT: the place where an organism usually lives. NATURAL SELECTION: the process by which individuals that are better adapted to their environment survive and reproduce more successfully

research scientist with a profitable side practice treating the syphilis infections of prominent London artists‚ was pursuing his pet theory--that his own nasal mucus had antibacterial effects--when he left a culture plate smeared with Staphylococcus bacteria on his lab bench while he went on a two-week holiday. When he returned‚ he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him‚ a spore of a rare variant called Penicillium

The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain
