Gram-positive bacteria

ABSTRACT: This study was carried out to evaluate the effect of pretreatments prior different drying methods and temperatures on compositional quality of the dried mushroom. Oyster mushroom (Pleurotus ostreatus) was cultivated on rice substrate and collected samples were pretreated (steeped or blanched) by different solutions (0.1% sodium metabisulfite and 0.1 and 0.5% citric acid) and dried using oven at 50°C and 60°C, sun-drying at 30-35°C and microwave drying at 2.45 GHz until reached to…

stressed out red blood cells to create an environment where harmful malaria bacteria would not be able to thrive in. The cause was later isolated in 1956 by medical researchers as G6PD deficiency which is common in African and Mediterranean descents. G6PD is an enzyme that protects red blood cells from damage, and premature death. This means that the bodies of people with G6PD deficiency will be weaker against harmful bacteria, and with primaquine stressing the red blood cells, the body becomes…

Jonathan Jeschke discusses a rapidly growing scientific discipline known as the four general hypotheses in modern Invasion Ecology. Ecology is defined as the study of interactions between organisms and their natural habitat. Jeschke elaborates using different methods of hypothesis to disclose an unambiguous image of each ‘backbone of science’ as a whole and individually and the ways it is beneficial to us. However, the most important influential invasion hypothesis I believe is Biotic Resistance…

Purpose statement To see how cells become competent in order to observe gene transfer, for competency plays a key role in order for transformation to take place. Transformation Transformation is a process which involves the change in a bacterial cells genetic makeup due to the uptake of exogenous DNA (Lorenz and Wackernagel, 1994). This process can happen in two different ways, either naturally or artificially. Natural Natural transformation is the bacteria’s ability to acquire naked DNA that…

regarded as a distinct avian disease until 1920s. In 1932, the causative agent was isolated and named as Haemophilus gallinarum afterwards. Based on the identification of Page in 1960s, H. paragallinarum was isolated and regarded as the true causative bacteria. However, recent researches have confirmed both these two species belong to Avibacterium genus and are both reason for the fowl coryza, while most researches suggested Av. paragallinarum plays the major role in recent outbreaks (Blackall &…

Katherine Sanders BIOL-1406 Dec. 4, 2017 Formal Lab Report I. Purpose / Objectives The purpose of this lab was to imitate natural selection in a controlled environment. II. Hypotheses Hypothesis 1 – Size Null: There will be no difference in which of the beans will be picked first, based on size. Alternative: The smaller beans will be more likely to be picked last, therefore, they will survive and reproduce. Hypothesis 2 – Color Null: There will be no difference in which of the…

Introduction to Cell Biology – Unit 10193 – Chloe Barrett This essay discusses the difference in prokaryotic and eukaryotic cells, two types of specialised eukaryotic cell, and the relation of the structure of cell membranes to their function of moving substances in and out of cells. Prokaryotic and Eukaryotic cells are two very different, but also very similar cells. There are many differences between them that can help to associate between each one. Eukaryotes are any organism that…

Hookworms are small and short worms. They live in the small intestines of man. They are called hookworms because each of them has hooks on its head around the mouth. The worm attaches itself to the inside wall of the intestine by these hooks. Hookworms feed on blood. They suck this from the wall of the intestine to which they are attached. There are often several hookworms at the same time in the child's tummy. All of them feed on the blood of the child. Therefore, one of the major effects of…

Costus speciosus (J.König)sm is a widely used medicinal plant in Ayurvedic medicine. Scientific literature prove about various therapeutic properties of its rhizome and leaves. The effectiveness of Costus speciosus (J.König)sm leaf aqueous extract on reversing insulin resistance was studied and data were published previously. This study was designed to evaluate the dose-response relationship of Costus speciosus (J.König)sm leaf aqueous extract. Insulin resistance induced rats were treated with…

ANALYSIS OF RESULTS: The limiting factor of area is the size of the polystyrene cup used in the experiment. Each of the polystyrene cups was the exact size in order to be able to determine how different amounts of fertilizer affected the duckweed growth. Hence, the factor of size could not be investigated as each different amount of fertilizer was exposed to the exact same area. This can be linked to the literature review that discusses how the area where it is growing affects duckweed growth.…
