shores 470 miles away from Bligh Reef. An estimated 250,000 seabirds, 2,800 sea otters, 300 harbor seals, 150 bald eagles, up to 22 killer whales, and billions of salmon and herring eggs died as a direct result of the spill. Despite mechanical and bioremediation cleanup efforts between 1989 and 1992, and again in 1997, oil was still present in a large area of the Sound by 2001. Ten years after the spill, only two species (the bald eagle and the sea otter) of the original list of twenty-eight directly

Research Paper on Maritime Technology and Environmental Regulations 1-0: Introduction Two vessels collided on august 1990 near Gibraltar in Spain resulting in a sea disaster and oil spill. Sea Spirit along with the Norwegian gas tanker collided head on causing a spill of about 8000Tons of oil. Oil contamination in the marine spread far, even reaching the Moroccan coast in form of cakes, tar balls, and oil packs. Similar to this disaster is the major oil spill that occurred on July in 1979 near

There are many examples today on the use of genetic engineering and biotechnology. First and foremost is creating bacteria that improve human insulin; others are frost and pest resistance in agriculture and the breakdown of pollutants involved in bioremediation. Transformation is described as the uptake of naked DNA in the environment by a recipient bacterium (Bio 1162 lab manual). The foreign DNA contains the desired genetic material that is inserted into the host organism.

conditions. The decolourization/removal of textile dyes like bromophenol blue, methylene blue, methyl green, and malachite green, in addition to various other industrial dyes, using bacteria isolated from soil has been an important area of research for bioremediation and the present work is focused on this specific aspect. The effect of independent variables such as time, temperature, pH, and agitation on decolorization efficiency of bacteria has been optimized. Biodegradation of methylene blue and bromophenol

It is amazing to think that an accidental observation led to the production of one of the most widely used antibiotics still in use today. Furthermore, it is even more amazing that this antibiotic derived from a fungus. In 1928 a bacteriologist by the name of Alexander Fleming, while working on a project, made an observation on a contaminated culture plate of staphylococci by a mold. He noticed a bacteria-free circle around the mold growth and discontinued his project to focus on his accidental

suffer from problems such as enzyme leakage from matrix when the interactions are relatively weak. Nonspecific Adsorption The simplest immobilization method is nonspecific adsorption, which is mainly based on physical adsorption or ionic binding. In physical adsorption, the enzymes are attached to the matrix through hydrogen bonding, van der Waals forces, or hydrophobic interactions; whereas in ionic bonding the enzymes are bound through salt linkages. This method is the easiest method of preparing

INTRODUCTION Many recognized species on Earth are classified according to their presumed evolutionary relationship. Taxonomy is the branch of biology concerned with identifying, naming, and classifying organisms. Today, taxonomists use the following categories of classification: species, genus, family, order, class, phylum and kingdom. Recently, a higher taxonomic category, the domain, has been added to this list.Kingdom is the second highest taxonomic rank below domain. It is divided into categories
