Genetic engineering
deliberate modification of an organism's genetic information by directly changing its genome (DNA)
-
recombinant DNA technology
procedure use to carry out genetic engineering
-
Bt corn
- bacillus theuriniensis
- -gram positive
- -produces toxin which is effective toward catepillars
-
microbial ecology
study of behavior and acitivities of microbes in natural environment
-
PCR
- denature target DNA (heating)
- -anneal primers that are specific to DNA
-
DNA Vaccines
plasmid with genes from pathogen inject, to produce immune response
-
Bacillus thuriniensis.
- Bt corn
- -gram (+), produces toxin which is effective toward caterpillars, move toward palnts
-
phytoremediation
to take up metals
-
biodegradation prcoess is best way to carry out..
to use natural microbe
-
termite hindgut.
symbiosis. microbe/host relationship
-
mutualism:
relationship beneficial to both partners
-
obligatory relationship.
partners cant survive without each other
-
H2 being released..
- microbe releasing this is..Methanogenic, Ardraea, and Acetogenic bacteria
- -methanogienic archaea makes CH4 and Acetogenic bacteria makes acetate
-
Thiobacillus ferroxidens
love acidic environment
-
pyrite.
form of iron and sulfur,..
-
acidic conditions
make metals very soluble, and make toxic liquid/condition
-
Pseudomonas aeruginosa.
found in soil and opportunistic pathogen
-
infection.
competitive relationship between host and parasite.
-
disease.
host lose competition resulting change in general good heatlh
-
opportunistic pathogen.
microbe are benign til defenses are down, microbes invade.
-
highly virulent.
alawys cause disease
-
moderately virulent.
sometimes causes diseases
-
avirulent.
- do not cause disease
- eg. Microcacuslibious
-
endemic.
disease mat occurs at low level in certain area
-
epidemic.
breaks out in explosive proportions within population
