The alignment results show that primate β-defens<strong>in</strong>s are highly conserved.<br />
Humans and orangutans have <strong>the</strong> same am<strong>in</strong>o acid sequence but it should be<br />
noted that humans are more susceptible than orangutans to M tuberculosis.<br />
The multiple sequence alignment file was used as <strong>in</strong>put to <strong>the</strong> Phylip<br />
program to construct a phylogram. The highly-parsimonious phylogram implies<br />
that β-defens<strong>in</strong>s <strong>of</strong> primates, particularly, those <strong>in</strong> <strong>the</strong> Family Hom<strong>in</strong>idae, are<br />
coded by homologous genes and are derived from a common ancestor. However,<br />
additional knowledge on <strong>the</strong> natural history <strong>of</strong> β-defens<strong>in</strong>s and analysis <strong>of</strong><br />
statistical methods are needed to make sure that <strong>the</strong> phylogram is evolutionary<br />
sound.<br />

Use <strong>of</strong> Garcilaria spp. <strong>in</strong> <strong>the</strong> bioremediation <strong>of</strong> eutrophic<br />
aquatic ecosystems<br />

ABSTRACT<br />
Gracilaria verricosa, a species <strong>of</strong> red algae (Rhodophyta) was used <strong>in</strong> <strong>the</strong><br />
bioremediation <strong>of</strong> eutrophic aquatic ecosystems. This research was conducted to<br />
curb <strong>the</strong> grow<strong>in</strong>g problem <strong>of</strong>, eutrophication, a result <strong>of</strong> <strong>the</strong> <strong>in</strong>creas<strong>in</strong>g amount <strong>of</strong><br />
nutrients <strong>in</strong> <strong>the</strong> aquatic ecosystem.<br />
Before experimentation, coliform test<strong>in</strong>g was conducted for four<br />
consecutive weeks on <strong>the</strong> PSHS pond to ascerta<strong>in</strong> that eutrophication was actually<br />
occurr<strong>in</strong>g. Three equal amounts <strong>of</strong> samples were <strong>the</strong>n placed <strong>in</strong> separate<br />
conta<strong>in</strong>ers and equal amounts <strong>of</strong> Gracilaria verrucosa bought from a local market<br />
were <strong>the</strong>n soaked <strong>in</strong> each conta<strong>in</strong>er. One set-up was placed completely under<br />
sunlight, ano<strong>the</strong>r under a shady area, and <strong>the</strong> last was completely covered to<br />
prevent sunlight from enter<strong>in</strong>g. After seven days, <strong>the</strong> water samples were<br />
subjected to coliform test<strong>in</strong>g.<br />
Initial test<strong>in</strong>g on <strong>the</strong> water source showed that coliform count <strong>in</strong>creased,<br />
confirm<strong>in</strong>g that <strong>the</strong> water source was eutrophic. After <strong>the</strong> treatment with<br />
Gracilaria verrucosa, however, <strong>the</strong> coliform count and heterotrophic plate count<br />
did not decrease for all set-ups.<br />
The effectiveness <strong>of</strong> Gracilaria spp. <strong>in</strong> bioremediat<strong>in</strong>g eutrophic aquatic<br />
ecosystems could not be determ<strong>in</strong>ed due to <strong>the</strong> use <strong>of</strong> fresh water samples,<br />
which may have caused <strong>the</strong> saltwater species, G verrucosa to die.
