Pollution Control -
Biological systems to clean up a contaminated site (other
than sewage treatment) i.e. removing Heavy Metals From Soil,
degrading waste through living organism (Pseudomonas for
living microbes toxic to pest, e.g., Bacillus
thuringenesis spores, which are toxic to the cotton insects are
sprayed over Cotton plant.
Culturing and inoculating Nitrogen fixing microbes in the field
devices which use a biological element
(an enzyme immobilized on an electrode’s surface) to measure
something (a substrate like any Pollutant) , so that a
current or voltage gets generated whenever both encounter (process
environmentally friendly sources of power and energy.
Biotechnology helps in detecting and Improving Methanogens
Strains of bacteria to increase biogas production.
microorganisms having Hydrogenase and Nitrogenase genes.
– It is a fuel derived from transesterification of vegetable oils or
animal fat, which is used in unmodified diesel-engine vehicles.
degraded Lands, by growing stress and pollution tolerant plants.
Stress (unfavorable environmental condition which prevents water
absorption by plants) Tolerant Plants- through inserting
stress tolerant genes in the plants.
Micorrhizae (microbes which fix atmospheric nitrogen etc and thus
have symbiotic association with the plants) in agriculture
and forest plants cultivation.
Biodiversity is the diversity/variety of life in this planet.
Diversity exists among various genus, species or within the species
or varieties etc. These variations or diversities are the letters of
the alphabet of life in this earth.
Searching for new Biological resources
(plants, microbes) which could be sources of natural products and
Phytopharmaceuticals; Biodiversity Identification
can be done Through RFLP (Restriction fragment length
polymorphism) study, in which DNA is isolated from different plants
of a same or different species and compared to find out any new
useful gene present among the plants.
it is also done by Micropropagation (tissue culture) of
has been successfully achieved for animal conservation (e.g. in
Endangered Species like Panda).
Efforts are on to multiply the number of chettah, which has become
extinct in India through
similarly as the sheep Dolly was cloned.
