Adsorption
It is the use of solids for removing Substances
from gaseous or liquid solutions.
Adsorption phenomena are operative in Most
natural physical, biological, and
chemical Systems, and adsorption operations
employing Solids such as activated carbon and
synthetic Resins are used widely in industrial
applications And for purification of water and
wastewaters

ISOLATION OF SOME NATURAL PRODUCT MATERIALS
FROM SOME MARINE ALGAE

• Marine natural products have attracted the
  attention of biologists and chemists the world
  over for the past five decades. As a result of
  the potential for new drug discovery, marine
  natural products have attracted scientists from
  different disciplines, such as organic chemistry,
  bioorganic chemistry, pharmacology, biology and
  ecology. This interest has led to the discovery
  of almost 8,500 marine natural products to date
  and many of the compounds have shown very
  promising biological activity. The ocean is
  considered to be a great source of potential
  drugs.

Marine Biotechnology

• DNA damage evaluation

Biotechnological tools are being developed for
the purpose of environmental monitoring and
pollution assessment
When the biological life is attacked by
some Harmful pollutants such as PCBs, and
Transition metals (e.g., Fe Cu), a Serious
damage may be developed in the Terms of
OXIDATIVE STRESS.

The Marine pollution Lab. Evaluates the DNA
damage via a special new colorimetric technique.

• Enzyme assay

Antioxidant enzymes such as catalase can be used
as a bioindicator for pollution
11

• Lipid peroxidation

The free radicals originated from oxidative
stress attack the unsaturated Lipids and the
resulting chain reaction is terminated by the
production of lipid Breakdown product such as
MALONDIALDEHYDE (MDA)
