At first he noticed the green mold of penicillin grown in culture dish of staphylococcus, in this way he discovered the Penicillium. What is fungi? Fungi are group of living Microorganism classified in their own kingdom, that means its neither not plants or animals or bacteria. Fungi are Eukaryotic organism such as yeast, molds, mushrooms, etc... Fungi are lack in photosynthesis, that means chlorophyll not present.  What are the types of fungi          The fungi are classified into 4 divisions. recently added one, 1. chytridiomycota   -   chytrids 2.Zygomycota        -   bread molds 3.Ascomycota        -   yeasts and sac fungi 4.Basidiomycota    -  club fungi 5. Phylum Glomeromycota What are the characteristics of fungi ? Heterotrophic: fungi needs energy so it depends on other plants and animals to grow this is k

  VIROLOGY:     The study of virus taxnomy, disease-producing properties, cultivation and genetics is know a Virology. " Martinus Beijerinck" is a father of virology. He discover virus or filtered infectious substance in Tobacco plant. " Walter Reed" Discover the first human virus in 1901. VIRUS : A Microorganism that is smaller than bacteria, that can grow and reproduce in other living cells. Virus are not made upof cells, they cannot keep themselves in a stable state, donot grow and cannot make their own energy. Virus can see under Electron Microscope or special type of microscope. CORONA VIRUS: Coronaviruses cause Acute, mild upper respiratory infection(common cold). STRUCTURE: v   Spherical or pleomorphic enveloped particles containing single-stranded of positive sense RNA(Mr 6 X 10 ⁶) associated with a nucleoprotein within a capsid comprised of matrix protein. v   The envelope bears club-shaped glycoprotein projections. v   SARS-CoV-2 which belong

WHAT IS CULTURE MEDIA...?          Any Microorganism that need to grown in  a place with all suitable nutrients and environment is known as culture. like that bacteria  need to grow with suitable Culture Media.     Bacteria have to be grown or cultured for them to be identified as only rarely can they be recognized by  morphology alone. The study of bacteria involves the study of bacteria population rather than of single bacterial cells. In humans and animals bodies as well in another natural sources bacteria occur as mixed population. By appropriate procedures they have to be separated or isolated on culture media and grown as pure cultures for study.         The original media used by Lousie Pasture were liquids such as urine or meat broth.  Liquid Media: Liquid media have many disadvantage bacteria growing in liquid media may not exhibit specific characteristics for their identification. it is also difficult to isolate different types of bacteria from mixed population using liquid m
