preventivo en el huésped. El concepto de alimentos funcionales (AF) tiene su origen en una mayor comprensión de las bases moleculares de la relación existente entre alimentación y salud y la posibilidad de contar con reguladores biológicos (donde las bacterias lácticas juegan un papel protagónico) que disminuyan el riesgo de contraer enfermedades. Los microorganismos comúnmente empleados como probióticos se encuentran disponibles comercialmente a través de laboratorios o industrias alimenticias a nivel

Protista, Fungi, Plantae, and Animalia. 1. KINGDOM MONERA [10,000 species]: Unicellular and colonial--including the true bacteria (eubacteria) and archaebacteria. ndividuals are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus. Monera are usually very tiny, although one type, namely the blue-green bacteria, look like algae. They are filamentous and quite long, green, but have no visible structure inside the cells. No visible feeding

1. True or false: Holding food in a steam table above 140F (60C) kills disease-causing bacteria and eliminates the problem of food poisoning. Explain you answer. False. Bacteria will not multiply at 60C, but most are not killed. 2. True or false: Canning food eliminates air so disease-causing bacteria can’t grow. Explain your answer. True. Canned and bottled foods that are unopened are not likely to support bacterial growth in their normal state. 3. Which of the following foods can become

solution has no effect on this bacterium besides a slight drying effect on the wall, The pink counterstain does bind the cells but it is not seen because covered by a darker purple colour primary stain. Bacillus subtilis are Gram-positive rod shaped bacteria that appear as small chains or single cells. They have thick peptidoglycan layer that can retain the purple stain from crystal violet. Saccharomyces cerevisiae are circular which occur singly or in a group. They do not respond to gram staining due

microbial media are really best for growing microorganisms. They provide the right nutrients that allow good growth. However, if a commercial agar medium is too expensive, you can prepare homemade gelatin plates that will allow many fungi and some bacteria to grow. This homemade medium can be poured into sterile disposable petri plates or, if those are too expensive, can be poured into foil muffin cup liners that can be stored in plastic sandwich bags. Materials • plain gelatin • water • sugar

Experiment 4: Isolation of Individual Colonies For the experiment, isolation of individual colonies I was allowed to compare enriched, complex, and synthetic media. Enriched media contains some important growth factors necessary for growth of specific organisms or an organism that has a complex nutritional requirement. This "growth factor" contains vitamins, amino acids, blood components, or carbon sources. Enriched media is used to harvest as many different types of microbes as are present in a
