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 DDT
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
the dropping trials, one piece of bread was swabbed with a sterile swab and then transferred to a media plate, and then the same process was followed for a slice of banana. One floor tile was then disinfected using CDC-10 disinfectant. Apply S. Marcescens bacteria were applied using a sterile swab in middle of the floor tile. The first piece of banana was then touched to the bacteria infected floor for one second. The banana was then swabbed on the side that became exposed to the bacteria and then
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 Introduction
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
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
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.
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
2. 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
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
