Abstract Microbial Induced Calcite Precipitates (MICP) is a new and sustainable technology used to improve the properties of construction materials. This technique works by introducing bacteria solution (e.g., Sporosarcina pasteurii, B. megaterium, Spoloactobacilus, Clostridium and Desulfotomaculum) into the soil matrix, and then injection of a chemical solution consisting of urea and one of calcium salts (e.g., calcium chloride and calcium acetate) into the soil matrix several times. A number of…

variations in the orbit of the planet that altered the amount of energy that Earth received from the sun (Severinghaus, 1999). The warming trend the we are observing right now is particularly important because it’s proven to be mainly human-induced and proceeds at a rate that is unprecedented in the past 1,300 years (IPCC, 2007) There is a strong, credible amount of evidence, based on numerous lines of research, which suggests that climate is changing and that these changes are in large part…

Evolution of Microbial Resistance Antimicrobial resistance is the ability of a microorganism to withstand the effects of an antibiotic drug in which it was originally sensitive to. Resistant organisms are able to withstand attack by antimicrobial drugs such as antibiotics, antifungals, and antivirals which makes standard treatment procedures ineffective. Antimicrobial resistance is something that has evolved naturally via natural selection through random mutations, it can also be achieved by applying…

are many microbial cells and the number of microbial cells is 10 times greater than our human cells on the surfaces of our bodies (1, 2). In addition, the human gastrointestinal tract is the greatest collection of microbial cells, which contain plenty of bacteria, including different classes and subclass of microbe. Microbial cells reach around from ten million to one trillion cells per one gram of body weight in the human gastrointestinal tract content (2). The genomes of the gut microbial are about…

Microbial Unknowns Objective: In the past couple of weeks, our class received a single broth that contained two species of bacterium. One bacterium was gram positive and one bacterium was gram negative. We were required to use our techniques and knowledge we learned in class to separate and identify the two species we were given in our broths. Methodology: Day One: On the first day of our Biochemical Unknown Lab we were given a tube that contained broth media which held two different types of…

the common belief that the cause of obesity is solely due to an excessive consumption of food. However, recent studies have made a correlation between obesity and the diversity of microbiota in the gut. One project of focus (“Obesity alters gut microbial ecology”) measured the proportions of gut microbes in mice populations and hypothesized a relationship between this bacterial number and body mass. The significance of this field of study is vital to the issue of obesity. First, such a discovery…

in their removal or sequestration in one way or the other and thereby clean up the environment. These special classes of microorganisms are considered very important for the environment as they considered as “Natural Cleansers” of the ecosystem. Microbial bioremediation can be seen happening almost anywhere such as soil, water, sludge, sewage, inside plants and animals, in agricultural fields and so on. In other words we can say that bioremediation may occur in a vast range of surroundings depending…

by the environment so some members of the population must die for the needs of the colony. Or, the environment changes and requires a reduction in colony growth to survive as a whole. Q2. Explain two methods used to measure microbial growth One method used to measure microbial growth is to use a 'counting chamber,' or special slides to render the microscopic population visible under a microscope. "Only dense suspensions can be counted (>107 cells per ml), but samples can be concentrated by centrifugation…
