1. The Ballast Water Management Convention (BWMC) Ballast water management is defined as the “mechanical, physical, chemical, and biological processes, either singularly or in combination, to remove, render harmless, or avoid the uptake or discharge of Harmful Aquatic Organisms and Pathogens (HAOP) within Ballast Water and Sediments. (IMO, 2004) In February 2004, the IMO adopted the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (the Ballast Water…

Biochemical Unknown I. Introduction Cultural Characteristics or morphology and biochemical tests can be used to identify and classify microorganism. By culturing microorganism in nutrient broth, slants, and on nutrient agar plates, the cultural characteristics or morphology can be determined. In this lab, the test tube 2 was incubated in a nutrient broth. The pigmentation of the tube was yellow. The media for test tube 2 was turbid. There were a few sediment on the bottom of the broth. In…

Problem What is the aquatic health of the Nequasset lake tributaries as analyzed through chemical and biological parameters as well as physical habitat assessment? What factors, both natural and human-influenced, contribute (positively or negatively) to the health of the Nequasset lake tributaries? Background Information Weather or not we realize it, as people that (presumably) live in the Bath area, the streams that flow into Nequasset are very important to our survival. They are numerous, and…

There are many factors that contribute to the conclusion that the steelhead trout will and will not be able to reestablish themselves in the Arroyo Del Valle presently. Some of the most important factors for the re-establishment of the trout are the relatively stable pH, adequate DO levels, and low pollution. From our graphs, it is evident that the pH of the creek is consistent around 7, which is a pH that the steelhead can establish themselves and live in. Steelhead trout require a DO level…

Group Members Zoe Ching, Juliet Contreras, Ailly Lam, Aleksi Ska. Background information Enzymes are biological catalysts, which speed up the rate of chemical reactions. The pancreas produces a concentrated solution containing a mixture of enzymes – amylase, lipase and protease. In this experiment you will examine the effect of protease on casein, the protein found in milk. When the protease breaks down the casein, the opaque solution will become transparent. Theoretically, Enzyme activity…

CRP was identified from patients with acute pneumococcal pneumonia at the Rockefeller Institute for Medical Research (Tillett and Francis, 1930), a name that reflects its reaction with the C-polysaccharide of Pneumococcus. This pentameric protein with MW 118 kDa has five non-covalently bonded and non-glycosylated identical subunits of 206 amino acids each to form a disk-shaped pentagon (Fig. 1). CRP has been proven as an early indicator of infectious or inflammatory conditions as well as a…

Materials and Methods Materials used in experiment 1.1A: Nutrient agar plate Materials used in experiment 1.1B: Nutrient agar plate, Sterile cotton swab In experiment 1.1B a nutrient agar plate was opened and left in an arbitrary spot in the laboratory and left untouched for three hours, at the end of the lab it was collected and incubated at . In part B a swab/swab rinse method was preformed in order to inoculate the nutrient agar plate. A sterile cotton swab was taken out of its packaging, an…

Abstract Water treatment methods were recorded as early as 4000 B.C. It was not till the early 20th century that chlorination was implemented to distributing water systems in the U.S. Today, chlorination remains the most widespread method of purifying drinking water. Chlorine has eliminated waterborne diseases like cholera, typhoid and dysentery. It also eliminates slime bacteria, molds and algae that grows in water supply reservoirs. Although, high concentrations of chlorine are toxic and…

Introduction: The purpose of the tests (culture media, motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the…

Hydraulic fracturing, also known as fracking, is the process of drilling and injecting fluid into the earth’s surface at high pressures in order to fracture the clastic sedimentary rock or shale rock surface. Fracturing the shale rock releases the natural gas, petroleum, or water that could be trapped inside these underground natural reservoirs. The wells are drilled vertically into the earth’s surface for hundreds or thousands of feet and include horizontal or directional extensions to allow…
