| Summary: | Sea cucumbers are soft-bodied marine organisms found in the benthic environment which are known as
trepang, gamat or timun laut by locals. Sea cucumbers are commercially exploited for their body extracts due to their
therapeutic properties and as culinary demands. Moreover, sea cucumbers are host to complex community of microbes.
However, less efforts were documented on the identification of these microbial communities using high-throughput
sequencing approach. The purpose of this study is to identify the gut microbiome of the sea cucumber from Stichopus
ocellatus species. For this study, the sea cucumbers were collected from a coastal area in Pahang, Malaysia. The gut
contents were sampled and processed fresh upon collection and maintained on ice prior delivery to the storage facility.
The DNA was extracted prior two steps Polymerase Chain Reaction (PCR) for amplicon library preparation by
targeting the V4 region of 16S rRNA. The prepared libraries were sequenced using the Illumina iSeq 100 system. The
raw data were analysed using QIIME2 and other bioinformatics software. Here, we observed that the gut of Stichopus
ocellatus is home for the genera of Vibrio, Tropicibacter, Desulfopila and Halioglobus. Remarkably, the bacteria from
the genus Vibrio are the most abundant bacteria colonising the gut microenvironment. This study suggests baseline
microbial community that inhibit the gut of sea cucumber that may confer biotechnological important bacteria for
pharmaceutical applications and drug development. |
