Transcript of Microbes

Mikrobit
Viruses
Place in ecosystem and interaction with organisms:
not organisms (no cell structure, no metabolism)
require a host cell to reproduce -> obligatory parasites
effective spreading (Prof. Bamford: "all organisms swim in the sea of viruses")
cause severe diseases both in animals and plants -> eg. considerable damage to agriculture
can alter the genomes of other organisms -> evolutionary factor
Prokaryotes
Role in ecosystem and interactions with other organisms
autotrophes: producers (eg. syanobacteria)
heterotrophes: consumers and detrivores, symbionts and pathogens
nutrient cycle (nitrosomonas)
genetic variability (mutations and recombination) -> eg. antibiotic resistence
Eukaryootit l. aitotumaiset
Alkueliöt
osa taudinaiheuttajia (esim. malarialoisio)
ei suoranaista hyötyä ihmiselle
Archaea
found all over, but in low numbers
difficult to grow in lab
poorly known
to avoid competition, they are specialiciced in extreme environments
methanogens
halophiles
thermophiles
no known pathogens
Structure
Meaning to humankind:
many pathogenic species are known but most of viruses are harmless
vaccines against pathogens
widely utilized in biotechnology
Yksisoluiset sienet: hiivat ja homeet
Yksisoluiset levät
Meaning to humankind
pathogens most often treatable by antibiotics (effect on bacterial specific structures or functions such as murein cell wall)
beneficial symbionts: vitamin production in the colon (K, B12), human microbiota (normal flora)
waste water treatment
food industry (eg. lactic acid bacteria)
widely used in biotechnology
ekosysteemissä kuluttajia, hajottajia ja taudinaiheuttajia (patogeeneja)
homeista allergiaa ja satotuhoja, mutta niistä saadaan esim. antibiootteja
hiivoja hyödynnetään biotekniikassa (eukaryoottien proteiinituotantokoneisto) ja elintarviketeollisuudessa (leipominen, alkoholikäyminen)
tuottajia-> biomassan ja bioenergian tuotanto
toimivat hiilinieluna
vapauttavat happea
