Serratia marcescens, a Gram-negative bacillus, was originally and solely considered a biological marker in the medicinal industry, due to its highly natural red pigment: Prodigiosin (Hejazi and Falkiner, 1997). The pigment has numerous roles within bacteria, which can be further translated into the pharmaceutical and medical domain. This bacterium naturally occurs in water, soil, on plants as well as in humans and animals (Khanafari et al, 2006), where it is deemed an opportunistic pathogen. S.marcescens
already carry out in the soil. Along with being easier, it can be much less expensive because the soil does not have to be pumped out of the ground for treatment (Environmental Inquiry-Bioremediation). Serratia Marcescens is a bacterium that is commonly used for bioremediation. The bacterium, Serratia marcescens, was first discovered by Bartholomeo Bizio in Padua, Italy in 1819. The bacte... ... middle of paper ... ...ppm of DDT. Effective degradation was achieved with an inoculum pre-exposed to
THE EFFECT MOIST VS DRY FOOD HAS ON THE AMOUNT OF BACTERIA PICKED UP OFF OF FALLEN FOOD Lindsey Alexander, Gabby Wnek, Raquel Montoya, and Lauren Burkhart Introduction Micro-organisms play a huge part in a human’s life. Microbes are given a bad reputation because they are often known for causing disease, but that is not always the case. Microbes are found on the surface of our skin, in our intestines, and everywhere else. In fact, humans need microbes to survive. Microbes make up more than 60% of
The tests explained above and completed to aid in the determination of the unknown bacteria were completed in a specific order which was supported with rationale and logic. A T – streak method was completed in succession to obtain a pure isolated colony. The T – streaks were completed with nutrient agar to give the organism nutrients and allow the organism to grow. Once a pure isolated colony was obtained, a Gram stain was completed which gave the Gram reaction and morphology of the bacteria. The
antimicrobial substances showed activity against Serratia marcescens. The molecular weight of the peptide from skin extract was found to be ~3kDa by SDS – PAGE and confirmed by zymogram analysis. Further the earthworm was identified by morphological and COI gene sequence analysis and resulted to be Wegeneriona sps. This study may lead to the formulation of new antimicrobial drug from the earthworm skin extract. Key word: Antimicrobial peptide; COI; Serratia marcescens; Wegeneriona sp; SDS-PAGE
(p.131). The benefits of Tobramycin therapy can overshadow the potential danger. Tobramycin is effective at reducing growth and reproduction of gram-negative bacteria. The bacteria P. aeruginosa, Klebsiella pneumoniae, Escherichia coli, Proteus, Serratia, Acinetobacter, Staphylococcus aureus are susceptible to Tobramycin. When treating enterococcal infections, which are part of the normal intestinal flora of humans, the addition of penicillin is needed. Tobramycin is used to treat external ocular
Pneumonia Journal Article Kellie Hale Mohave Community College NUR 122 Mrs. Port 9/8/2016 “In 2012, 1.1 million people were hospitalized in the US for treatment of pneumonia. The average hospital stay for these patients was 5.2 days. There were close to 50,000 deaths due to pneumonia and 95% of them were over the age of 65 (“Pneumonia”, 2016). Pneumonia is an serious condition and the pathogens that lead to pneumonia continue to spread throughout the hospitals and communities. Antibiotic
2.1 Surfactant and biosurfactant The amphiphilic molecules which is known as surfactants have been used widely in different industries including petroleum, environmental, food, agricultural, bioprocessing, cosmetic, and biological industries. Surfactants contain a hydrophilic part and hydrophobic part which make them capable to reduce surface and interfacial tension of liquids. However, these compounds are chemically synthesized which is mainly petroleum-based and toxic to the environment. These
DNA replication and transcription is stopped. Not much of levaquin is metabolized. The unchanged drug is 87%. Certain microorganisms are sensitive to levaquin, they are: corynebacterium species, streptococcus pneumonia, staphylococcus epidermidis, serratia marcescens and other penicillin-resistant strains. The recommended treatment dosage for levaquin is 250 mg, 500 mg, or 750 mg orally every 24 hours.
Blast fishing is just about as ludicrous, if not more so, in practice. It is a method of fishing by which explosives are utilized in order to stun or kill schools of fish for easy collection. The explosions indiscriminately kill large numbers of fish, along with any other surrounding marine organisms, and damage or destroy the physical environment, causing tremendous damage when used around coral reefs. This practice is considered by researchers to be one of the greatest threats to coral reef ecosystems
Pigments produced by microorganisms has been used to dye fabrics of different types. Talaromyces verruculosus produce a red colored pigment which is suitable to dye cotton and is harmless. Pigments from microorganisms give different types of shades of a color. For instance; Janthinobacterium lividum produce a pigment which gives purplish-blue shade to different types of fabrics. Thermomyces produce a yellow pigment used to dye number of fabrics specifically silk. NP2 and NP$ strains of Streptomyces
Reduce Pollutants From Stormwater Runoff “Most cities do not take sufficient measures to prevent run-off. According to the EPA, 40 percent of US rivers and lakes surveyed do not meet water quality standards. Urban run-off is one of the key culprits” (UN Water, 2016, para. 14). Stormwater runoff runs down such things as roads and yards that causes dangerous pollutants to enter and create damages to our water and wildlife. Runoff is the number one cause of water pollution and in order to stop it we
Ventilator-Associated Pneumonia and Oral Bacteria Nelya Sirotinskiy and Danielle Davidson DHYG 221 Columbia Basin College February 9th, 2017 Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infection associated with increased morbidity and mortality. It is recognized that 36-60% of all health associated infection-related deaths are attributable to VAP (Gupta et al, 2016). Ventilator-associated pneumonia is a lung infection that develops in a person who is on a
INTRODUCTION The purpose of the microbiological experiment was to applying different types of techniques and methods learned in microbiology lab to a bacteria so that it may be accurately and precisely identified. “The words accurately and precisely are not the same in microbiology, accurately has the meaning of if repeated the same answer continues to be the result, precisely has the meaning of the correct answer.” “Microbiological experimentation often involves test that determine the ability of

Comment on class result with respect to differences in filter types, differences in filter assemblies, and overall on the confidence you would have in using this type of sterilisation process in preparation of pharmaceutical products. List the factors that may cause contamination during filtration. (20 marks) Factors that may contribute to contamination: • Not disinfecting work area • Fibres from filter, clothing etc. • Potential chemical release from filter, syringe etc. • Assembly of Swinnex
Acne is described as the most common skin disorder that affects 85% of individuals ranging from pre-teenagers to grown adults, specifically between the ages of 12-24 (Tahir 2010). In the midst of the 50 million people affected with acne vulgaris, adolescences are generally most susceptible due to elevated sexual hormones (Zaenglein et al., 2016). Numerous factors increase the production of acne vulgaris. Inadequate diet, menstruation, sweating, over exposure to ultra violet rays and excessive stress
Introduction The urinary tract makes and stores urine, which is one of the waste products of the body. Urine is made in the kidneys and travels down the ureters to the bladder. The urethra in a male is about 8 inches (20cm) long and opens at the end of the penis. The urethra provides an exit for urine as well as semen during ejaculation (Urology Health, 2014). Normal urine is sterile and contains no bacteria. However, bacteria may get into the urine from the urethra and travel into the bladder
Beautiful beaches, a hot sun, glistening sand, and a clear ocean would make the perfect vacation, right? Many of us would enjoy being somewhere tropical. This kind of vacation won’t last much longer if we don’t start taking care of endangered coral reefs now! World government leaders should establish laws to protect them. People may ask, “If coral reefs are in such danger, why don’t we fix the problem since they provide benefits for the whole world?” Frankly, it’s not that simple. Protecting endangered
