Alga Merah (Gracilaria verrucosa) sebagai Bahan Bakto Agar
Abstract: The used of bacto
agar in microbiological studies increased tremendously, however, up till now,
to fullfill its high demant the scientist were stil relying on imported bacto
agar eventhough domestic production of bacto agar was as goog and reliable as
those produced commercially overseas. The current study we focuseon the
production of bacto agar from red algae Gracilaria verrucosa using fell press
technique; followed by quality analysis of the product. Red algae samples were
collected from two different locations (Bekasi and Subang). Quality of the
product was tested for its content, acid insoluble as content, overall as
content, pH, gel strength and its ability to be use as culture media to culture
Escherichia coli and Staphylococcus aureus. Microbiological test was performed
via pour plate. The results clearlydemonstrated that red algae sample from
Bekasi produced bacto agar that meets the criteria of commercial bacto agar. It
has 10.3% water content, 3.9% overall as content, 0.4% acid insoluble as
content, pH of 7.3 and gel strength of 600.8-602.8 g/square cm.
