Bioremediation

Environmental biotechnology refers to the application of biotechnology which is used for finding a way to solve the problems related to environment, in both conditions like in manmade ecosystem e.g. waste water treatment plants and in environment e.g. bioremediation, biodegradation of hazardous wastes and production of biofuel and biogas [3]. It is a field of scientific knowledge which involves microorganisms and products of them, to be used to prevent environmental pollution by utilizing…

Lead (Pb) is one of an important contaminant surrounding our environment. Lead occur naturally in all soil and water (1), or can be found deep within the ground located in ore (2). Although lead can be found in small quantities, there is a great quantity of lead flow in the environment that is detrimental to human beings and plants. However, despite lead is a toxic metal, there are still lots of households products contains lead; burning of paper products, discarded rubber, battery casings, and…

hat is a chemical spill? A chemical spill is an uncontrolled, accidental release of a chemical into the environment. What is remediation of chemical spills? The removal of unwanted, hazardous contaminants from an area. There are many methods by which this can be accomplished. Sodium Hydroxide can be fatal to aquatic animals. It is responsible for more than half a million fish in British Columbia in 2005. Phosgene can be released as a gas from household paint removers when exposed to heat. If…

The Boettcher collection at the Colorado Governor’s Residence contains several Carrara marble sculptures. The Palm room, the Palm Dining Room, and Well room hold a large amount of marble. It is apparent that the Boettchers were fond of Neo Classical Italian works and materials. Four marble sculptures in particular stand out based on their location, size, and the intricate carving details and motifs. This paper will focus on the symbolism and materials of the two marble console tables with…

Monday morning a blizzard struck, producing 25-foot waves and less than 1% of the spilled oil was recovered (Schlager 5). The other controversial processes were bioremediation, fertilizer, has been sprayed onto the beaches to stimulate growth from the naturally occurring bacteria and degrade the oil and changed it to form a harmless substance (Schlager 5). The workers involved with the wildlife-collecting dead animals…

Introduction The proper identification of microbes is an important practice in the medical field as well as other areas of research. Isolation of microbes from a mixed culture broth was performed with the finding of two different microbes; Escherichia coli and Sporosarcina ureae. The isolation process was performed by streaking a mixed culture onto a nutrient agar plate, then transferring the isolated cultures after incubation for biochemical testing. S. ureae is discussed below. Biography…

Importance of Microbes Introduction It was long ago when Man realized that, along with animals and plants, he was also accompanied by some other organisms as well, and though which remained hidden from his eyes. Those organisms were unveiled by Anton Van Leeuwenhoek, who first saw the tiny organisms which accompanied Man through the lenses of microscope. Later it was found out that microorganisms inhabited each and every surface of earth, on man himself, or even inside him, resided under the…

Different batch experiments were conducted to access the effect of pH on removal of heavy metals by T1B1 strain. 100 ml of sterilized SE medium was inoculated into 250 ml Erlenmeyer flask containing 100 µl (107cells/ml) of bacterial suspension with HM (mg L-1): Fe (150), Mn (100), Ni (50), Cd (30), Cu (30) and Zn (50) with pH adjusted to 4, 6.5 and 9. Another set of experiments were set up by inoculating SE medium containing HMs (mg L-1 ): Cr+6 (100, 150, 200), Fe (100, 150, 200), Ni (50, 100,…

Quality of drinking water is the most concerned topic in China. In 2007, official estimates of the extent of water pollution in China were doubled. Clean water is key of human to survive, and also plants and animals need water to grow; therefore water quality has to be kept clean. Water pollution was caused by many human activities and it also has a great effect on the population that need an urgent attention. Over million people in China lack access to safe drinking water (Patricia). With a…

Due to its importance in size, the Yellow River is still a key resource for the Chinese civilization’s development. Nowadays industrial, agricultural and residential areas increasingly contribute to water contamination. However, there are measures that can be taken to reduce the amount of these pollutants. Current interventions addressing pollution control measures depend on the area of location of the river. In this approach, as part of the environment management, chemical and physical tests…
