2. INTRODUCTION
A GIS is a group of
procedures that provides
data input, storage and
retrieval, mapping and
spatial analysis for both
spatial and attribute data
to support the decision-
making activities of an
organization.
Ocean are the home to huge
microbial population and
diversity .Microorganisms
live in every corner of the
ocean and their habitats
are diverse, they are
distributed in open water,
sediment, bodies of
marine macro and micro
organisms, estuaries and
hydrothermal vents

3. OBJECTIVE
 To isolate the bacteria and actinobacteria from the Neil and Havelock
islands.
 Identify the isolated bacteria and actinobacteria by using molecular
techniques.
 To study the spatial and temporal variation of Biogeography of microbes
in Neil and Havelock islands.
 To understand the spatial-temporal regions through spatial mapping
techniques.
 To determine the comparison of the Neil and Havelock islands by the
biogeography of the microbial mapping

4. Sample collection
Isolation of marine bacteria & actinobacteria
(Kathiresan et al. 2005)
Identification of marine bacteria &
actinobacterial by Molecular technique
(Karuppiah,2011)
 Biogeography and microbial diversity (GIS
softwares)

5. Work so far carried out
• Sediment samples were collected from the Neil & Havelock Island,
Andamans
• Isolation of the marine bacteria and actinobacteria were made ,
strains were maintained in slants
• Marine bacteria & actinobacterial strains were identified using
molecular methods
• Mapping of the microbial diversity and biogeography process was
done
• Thesis writing is progress.
