- 1MICROBIAL INTERACTIONSYMBIOSIS
association of two or more different species of organisms. - 2Ectosymbiontorganism located on surface of another organism
- 3Endosymbiontorganism located within another organism
- 4Symbiontphysical contact between dissimilar organisms of similar size
- 5Consortiumhosts that have more than one associated symbiont
- 6Microorganism-Insect Mutualism-endosymbiotic microbe provides needed vitamins and amino acids
-insect host provides secure habitat and nutrients. - 7Protozoan-Termite Relationship-termite provides food for protozoan
-protozoan digests cellulose in wood particles, providing nutrients for termite - 8Cooperation-along with commensalism is a positive, but not obligate, form of symbiosis which involves syntrophic relationships
-benefits both organisms in relationship - 9Syntrophism• type of commensalism
-growth of one organism depends on growth factors, nutrients, or substrate provided by another organism growing nearby. - 10Commensalism-one organism benefits and the other is neither harmed nor helped
- 11Examples of CommensalismMicrobial succession during spoilage of milk
-fermentative bacteria produce acids that promote growth of acid tolerant species. - 12Predation-among microbes involves a predator species that attacks, usually killing its prey
- 13Microbial PredatorsBdellovibrio penetrates cell wall, grows outside plasma membrane.
- 14Parasitismone organism gains (parasite) and the other is harmed (host)
- 15Genomic Reduction• outcome of long-term parasitic relationship
-parasite loses unused genomic information - 16Ammensalismnegatives impact of one organism on another based on release of a specific compound
- 17Competitionoccurs when two organisms try to acquire or use the same resource
- 18Two Possible Outcomes of Competition• one organism dominates
– competitive exclusion principal
• two organisms share the resource
– both survive at lower population levels
