Characteristics of Monera The following points related to Monera characteristics will help you understand the kingdom of classification better. • Monera are about 1 micrometer in size and complex as living molecules. • The Monera cell structure is mostly unicellular and some organisms that form groups or filaments. • These organisms are the simplest prokaryotic cell structures. • The Monera cell structure lacks nuclei and many other cell organelles. • They have a cell wall made of polysaccharides

Contributors to Microbiology Pioneers of Microbiology I. Antonie van Leeuwenhoek (Oct. 24‚ 1632- Aug. 30‚ 1723) A. In 1676 Leeuwenhoek saw tiny organisms in water‚ he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes‚ blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work

Streptococcus (group A strep) and Staphylococcus aureus are one of the main causes of necrotizing fasciitis‚ one of the rarest causes of necrotizing fasciitis is Aeromonas hydrophila which is a gram negative bacterium and is usually associated with brackish waters such as lagoons‚ marshes‚ deltas and estuaries this strand of bacteria is very resistant to antibiotics‚ and it can lead to sepsis and infection of other body organs‚ another cause is

cause eye infections in men and women which can lead to blindness. It can also be passed from mom to baby during birth in the form of eye infections and pneumonia. HOW WAS IT DISCOVERED? c. Trachamotis was first discovered in 1907 by Giemsa staining by Halberstaedter and von Prowazek who took scrapings from individuals infected with trachoma and inoculated orangutans eyes with the samples. This demonstrated how the disease could be spread between infected individuals. In 1929‚ there was an

The microorganisms isolated from the soil were of staphylococcus strain and were gram positive‚ aerobic‚ coccus shaped bacteria. The fungal species were also identified‚ of which Aspergillus and Penicillium were dominant‚ followed by mucur‚ as sub dominant .This project aims to find out the water and soil quality of River and as it

REVIEW OF RELATED LITERATURE This investigatory project aims to make use of rambutan peeling extracts that is high in phenolic compounds such as tannin and saponin that exhibits antioxidant activity and antibacterial activity against pathogenic bacteria. Although the seeds contain such compounds the peeling exhibit greater amount of the said compounds. Rambutan is a very popular fruit cultivated in the Philippines and it is eaten in large amounts. The rambutans rind is quickly discarded and
