DNA Isolation from BacteriaIntroduction: The genetic information is essential to the life of the bacterium and is contained in a
singular molecule. There are basic steps of DNA extraction that are consistent across DNA purifications
chemistries disruption of cellular structure to create lysate, separation of soluble DNA cell debris and
insoluble material, precipitation, and separation of DNA, washing proteins and other contaminants, and
DNA storage. DNA carries its molecular structure for cell development and behavior
Method: Bacterial cells are cultured in liquid media by adding ethanol/isopropanol to the high
concentration salt solution. The collected cells are lysed, often done chemically using a reagent such as a
lysosome Write the name on the test tube containing detergent pour e coli solution from the test tube,
Remove the tube from hot water add two flat toothpicks full of meat tenderizer 55-60 degree Celsius.
Water bath 20 minutes. Remove the tube from hot water and add cold alcohol to the test tube. Let the
solution sit for 2-3 minutes without disturbing I, it is important not to shake the test tube.
Result When results are obtained to spool in the glass the DNA has an appearance of white
mucus. The isolation allows the chromosome DNA from a bacterial cell of e coli Gram (-) so the
treatment with some is not needed if the Gram (+) are more difficult to lyse and need Lytic enzymes.
Discussion Bacteria are the most abundant organism, bacteria pathogens are responsible for causing a
variety of diseases. DNA isolations are step by step method for isolating quality DNA from gram-negative
and gram-positive bacteria species. Bacterial cells are cultured in liquid media until it reach a maximum
density 2-3×10 cells/ml and then harvested. The lysis buffer method is used to separate DNA, the type of
membrane used to wash, and the method of DNA recovery.
Introduction: Microbiome cultivation-based isolation characterizes individual microorganisms
from microbiome samples in a defined environment. Many allergic proteins and non-allergic accessories
are involved in the plant’s defense against the environment. The focus is to analyze the colonizing
microbes on allergenic pollen. A prime cause of allergies is airborne pollens from plants and grass or
weeds causing allergic reactions and sometimes causing seasonal allergies.
Method: A study detects pollen with a container open for two minutes near pollen microbiota
and parameters of air pollution or pollen grass or weed. This experimental was set in isolation for a
week
Result: Most results from a characterized pollen model and little was known about the
colonization of pollen and there influences on the allergen expression in pollen. The pollen showed
bacterial and fungal from the specimen. The environmental plant showed possible factors of pollen
allergic and hay fever.
Discussion: Pollen allergies have rapidly increased over the last decades and causing
tremendous health problems. Allergies and airborne pollen from plants and soil are causing pollinosis
and sensitivities rates to pollen allergies. During spring and different seasons it is best to consult your
physician for seasonal allergies and stay away from pollen it can cause health issues.
