Microbial biodegradation Essays

Assalamualaikum and a very good morning I bid to my lecturer, Madam Rosyati, and my fellow classmates. My name is Aina Izzati Binti Mohd Khair, S37085 and I am from K1. Nowadays, the earth is facing global challenges such as climate change and pollution which occurs due to human activities. As some of us know, plastic bag is one of the contributors for waste pollution. This is why I strongly believe that the usage of reusable bags should be enforced in our country, Malaysia as the use of plastic

For pool owners, there is nothing more exhausting than cleaning the pool itself. Perhaps the common denominator as to why people want to own a pool is that they want to relax and enjoy it with their family and friends. That is the reason why most pool owners prefer to buy robotic pool cleaners. Having fun in the water is only the peak of an iceberg of having a pool. The rest of the iceberg lies on pool maintenance. It would probably take more time cleaning the entire pool than the actual leisure

Plastic In my opinion, there is no reason to keep wasting money on plastic, that is just going to end up causing risk to all living things on this planet. Did you know that about 8.3 billion plastic particles are made each year and about 6.3 million just end up as plastic waste in landfills? But, what happens when the landfills are full? Plastic pollutes the ocean and environment in many ways. Plastic usage is an extremely poor choice for everything and it should be banned because it pollutes

Nigel Courtenay-Luck, Ph.D., CSO of Antisoma, at a recent 9th European Biotech Crossroads meeting, talked about data from Phase 1 of a study on a new type of biomolecule called an aptamer. He said that aptamers are very similar to antibodies; they can both recognize and bind to antigens, they both have low nanomolar binding, and the pKa of both molecules can be modified easily. He said that they are ideal to be used as therapeutics because they can bind well(since they are 3-D) without causing an

The use of neurotoxin “periodic botulinum toxin” injections is considered to be the gold standard treatment for adductor spasmodic dysphonia. Botulinum toxin is produced by the bacterium clostridium botulinum and attains a “reversible neuromuscular blockade at presynaptic terminals, therefore, preventing the release of acetylcholine in response to action potentials” (Holden, Vokes, Taylor, Till & Crumley, 2007). Botox is directly put into the affected muscles of the larynx; therefore, injection of

species, are among the largest moderate halophilic bacterial groups with biodegradation potential of hydrocarbon pollutants (22,23). In this study, the optimum culture condition for crude oil biodegradation by MS1 determined by Taguchi method indicated that the use of statistical experimental design techniques

ABSTRACT PHB is a promising eco-friendly substance favorable for medical use. PHB was produced from local isolate Bacillus thuringenesis in a conc. 4.1 g/l using 30 g/L Sugar-cane molasses (SCM) at pH 7.5 and incubation temperature 35oC. PHB biodegradation by soil microorganisms were completed after four weeks. Cell cytotoxicity testing is one of the critical factors affecting the biomedical application of polymers. 50% cell cytotoxic concentration (IC50) = 130 mg/ml while non-toxic concentration

effective. It depends on the ability of living organisms to degrade the contaminants. Though intrinsic bioremediation processes are present, it is slow and has some drawbacks. Thus we use engineered bioremediation processes which depends on increased microbial growth and GEMs to get more effective and increased rate of removal of contaminants. Keywords: Bioremediation, intrinsic bioremediation, engineered bioremediation, 1. Introduction: In the recent years, the disposal and management of waste has become

INTRODUCTION A chemical reaction is the chemical change of atoms and molecules. They is are an essential part of daily life, and can be very useful for solving various problems. This essay discusses the use of bioremediation in oil spills, and the chemical processes involved. PROBLEM An oil spill is simply the release of liquid petroleum (also known as crude oil) into the environment. Large-scale oil spills are very problematic, as they as they can cause a multitude of short-term and long-term

Aerobic catabolism is the first initial step in microbial degradation of PAH which involves incorporation of two atom of oxygen into the aromatic nucleus of the PAH in an enzymatic reaction catalysed by peroxidases, monoxygenase and oxygenase (Das and Chandran, 2010). The incorporation of oxygen into the
