“…Our study indicates that seasons may play a role in the variation of bioactivity potential of sponge species; this was also observed even for the same sponge species because of different geographical locations. Kanagasabhapathy et al [ 47 ] reported that Psammaplysilla sp. collected from the Gulf Mannar in India showed bioactivity against P. aeruginosa (11 mm).…”

Marine invertebrates constitute a diverse group of marine organisms beneficial to humanity due to their therapeutic significance. The marine sponge species Psammaplysilla sp. 1 was collected from Philips Reef, South Africa, over a four-season period and assayed for antimicrobial potential. The physicochemical parameters of the collection site were also recorded. The sponge crude extracts’ antimicrobial activity was evaluated using an agar well diffusion assay against 5 pathogens. Phytochemical screening was conducted to identify the presence of 7 critical phytochemical groups. During the four seasons, the mean water temperature was 17.35°C ± 2.06, with autumn recording the highest (20°C) temperature. Antifungal activity was observed by Psammaplysilla sp. 1 (30 mm) against C. albicans, and this was higher than that showed by standard drugs ICZ-10 µg (15 ± 0.1 mm), FLU-15 µg (21 ± 0.2 mm), and VCZ-5 µg (17 ± 0.1 mm), respectively. Similar bioactivities were observed seasonally with Psammaplysilla sp. 1 (22 mm and 24 mm) during autumn and spring, respectively, against C. difficile while only crude extracts collected in spring showed bioactivity against C. albicans. Psammaplysilla sp. crude extracts showed broad-spectrum bioactivity against all test pathogens. DCM : ME crude extracts tested positive for the presence of 2/7 of the phytochemicals (terpenoids and flavonoids). GC-MS revealed several previously reported biologically active compounds such bicyclo[4.2.0]octa-1,3,5-trien-7-ol and phenol, 2,6-dibromo, some of which have been found in plants. This study revealed that sponge bioactivity is dependent on the season and further validated the antimicrobial potential of South African marine sponges.

Hasil yang sama ditunjukkan oleh penelitian Kanagasabhapathy et al, (2004) yang mendapatkan aktivitas antibakteri pada bakteri yang berasosiasi dengan sponge yang ditumbuhkan pada medium dengan salinitas 0%. Hal ini merupakan fenomena yang cukup menarik karena isolat bakteri pada kedua penelitian ini didapat dari invertebrata yang hidup di laut.…”

The search for new antimicrobial agents is very significant. The prevalence of antimicrobialresistance among key microbial pathogens is increasing at an alarming rate worldwide. Bacillusspecies produce many kinds of antibiotics which share a full range of antimicrobial activities.The aim of this research is to study antibacterial activity of three bacillus isolates (1A, 2J, 3L)which were isolated in Mentigi Beach, West Lombok. Assessment for antibacterial activity wasconducted using Overlaid Molten agar method on Nutrient Agar medium at different salinity(concentration of NaCl 0, 5, 10%) and different pH (pH 6, 7 and 8). The study showed that therewere different antibacterial activities at different salinity and different pH media. Production ofantibacterial at 0% NaCl concentration occurred only at pH 6 and 7 and had narrow spectrumcharacter (only for Gram positive bacteria). Addition of 5% NaCl made antibacterialproduction might occur at pH 6, 7 and 8 and had wide spectrum character (for Gram positiveand negative bacteria).
