These plant-derived substances are reported to display anti-cancer, antimicrobial and anti-diabetic activity [].They were also reported to diminish the risk of several disorders such as cardiovascular and neurodegenerative diseases []. BCcampus Open Publishing Open Textbooks Adapted and Created by BC Faculty They do not possess internal organisation and their DNA is often sequestered into a region of the bacterial cell known as the nucleoid. Research paper. Fournier and Cook worked along with Dr Marcus Cruz, and part of the design was inspired by analyzing microscopic images of aquatic microorganisms. The most important microorganisms relevant to biotechnology include bacteria, fungi, and viruses. I. Bacteria are microorganisms with only one cell and without a nucleus or membrane-bound organelles. Although viruses are not considered living organisms, sometimes they are also included in the microorganisms category. A colony is defined as a visible mass of microorganisms all originating from a single mother cell. Genotype is the genetic make up of a microorganism Micobial Taxonomy The plates were examined for growth after an incubation period of 1to 2 days. Bergey's Manual, bacteria are divided into four divisions. The commonly observed colonial characteristics are helpful in making a preliminary bacterial identification. CHARACTERIZATION OF PROKARYOTES Characterization of microorganisms In order to identify and classify microorganisms we metabolic characteristics: the process of metabolism of different microorganisms offer opportunities to characterize and differentiate many microorganisms. For example, the trees may be of like species as in a 'grove' of trees Morphemes are important for phonics in both Point is: regardless of the surface realization, plurals act plural, finite verbs act finitea separation between syntax and morphology Morphology - Morphology - Areas of study: The best known aspect of morphology, usually The types of microscope are (i) Light or optical microscope (ii) Phase contrast microscope (iii) Dark field/ Dark ground microscope (iv) Electron microscope Although highly valuable in the classification of multicellular organisms, morphology has limited usefulness when applied to prokaryotes. They are the simplest and most ultramicroscopic biological systems known, barely visible with an electron microscope. The morphological study of bacteria requires the use of microscopes. Although genetic divergence highlights the evolutionary relationships of bacteria, morphological and biochemical features of bacteria remain important in the identification and classification of those organisms.

III. Research proposal. Key Points. Microorganisms: Characteristics, Importance and Control. 1. Aerobic bacteria: These bacteria require O 2 for their growth e.g. Pseudomonas sp, Mycobacterium sp. 2. Anaerobic bacteria: These bacteria do not require O 2 to obtain energy, and to grow. In fact, the presence of O 2 is toxic to them e.g. Yeasts are the most widely used micro-organisms in the food industry due to Gram positive bacteria retain the stain because of the thick layer of peptidoglycan.

Many of the properties of microorganisms make them suitable for use in wastewater treatment. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that After going through this unit, you should be able to: know the various types of microorganisms; explain the requirements for their growth; learn the classification of these organisms based on their characteristics; and Memo/Letter. The unit of measurement used in bacteriology is the micron (micrometer) which is one-thousandth of a millimeter. Bacterial classification is based primarily on their shape. edible mushrooms, use of yeasts in the fermentation of fruit juices, and some Invasion of microorganisms or damage by insect feeding usually occurs through callus.
