“…Results found that the BCM formulation fed twice daily to steers at a rate of 0.30 g/100 kg liveweight (LW) with a grain-based feedlot diet, resulted in a significant reduction in CH 4 production (L/h) equivalent to 93.7% after 28 days of treatment. In addition, 40% of this response could be maintained over a prolonged period (60–90 days), without affecting LW gain and feed intake [ 87 ]. However, the authors acknowledged that this formulation was unlikely to be used in agriculture in Australia to reduce CH 4 emissions due to the fact that un-complexed BCM has an ozone-depleting effect and the manufacture, import and export of ozone-depleting substances, such as BCM, are prohibited by the Australian Government under the Ozone Protection and Synthetic Greenhouse Gas Management Act [ 85 , 88 ].…”

“…A. taxiformis concentrates halogenated compounds that are known to inhibit cobamide-dependent methanogenesis. In addition to CH 4 reduction the Bonnemaisoniaceae family (Rhodophyta) are amongst those with the highest and broadest spectrum of antimicrobial activity due to the content and diversity of volatile halogenated compounds [ 87 ]. The genus Asparagopsis Montagne alone is a particularly prolific source releasing over 100 of such volatile halogenated compounds [ 88 , 89 ].…”

Seaweeds contain a myriad of nutrients and bioactives including proteins, carbohydrates and to a lesser extent lipids as well as small molecules including peptides, saponins, alkaloids and pigments. The bioactive bromoform found in the red seaweed Asparagopsis taxiformis has been identified as an agent that can reduce enteric CH4 production from livestock significantly. However, sustainable supply of this seaweed is a problem and there are some concerns over its sustainable production and potential negative environmental impacts on the ozone layer and the health impacts of bromoform. This review collates information on seaweeds and seaweed bioactives and the documented impact on CH4 emissions in vitro and in vivo as well as associated environmental, economic and health impacts.

“…The production of antimicrobial properties has been considered as an indicator that particular seaweed has the capacity to synthesize bioactive secondary metabolites. Compounds with antiviral, anthelminthic, antifungal, and antibacterial properties have been detected in brow, red, and green algae [11,19]. Considering that Indonesia has vast area of oceans, and also is the largest island country in the world, investigation related to search of new biologically active compounds from marine products, i.e.…”

The current work aims to determine antibacterial activities of ethanol extracts of Eucheuma spinosum against Staphylococcus aureus. These were showed through inhibition zones formation, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) values. The MIC was determined using dilution test tube method, and the MBC was calculated using streaking method. Qualitative test was applied to determine phytochemical compounds in ethanol extract of E. spinosum. Results showed that ethanol extracts of E. spinosum at concentrations of 1%; 2%; 5%, and 10% (v/v) resulted in inhibition zones of 1.98; 4.14; 7.42; and 10.27 mm, respectively. In addition, concentration of 10% (v/v) was the MIC, and 15% (v/v) was the MBC values of E. spinosum extracts against S. aureus. The phytochemical analysis showed that alkaloids and saponins were the main components detected. Alkaloids positive tests were observed by the formation of brown sediment with Wagner's reagent, yellow sediment with Mayer's reagent, and orange sediment with Dragendorff's reagent. Saponins positive results were detected by the formation of stable foam when the extracts reacted with water and HCl. Overall, these results suggested that E. spinosum extracts have antibacterial properties against Gram-positive bacteria, i.e. S. aureus.

Indonesia merupakan negara yang kaya akan sumber keanekaragaman hayati dan memiliki kekayaan spesies laut tertinggi. Sekitar 45% spesies rumput laut dunia ada di Indonesia. Dikutip dari laporan ekspedisi Siboga, terdapat sekitar 782 spesies rumput laut di Indonesia dengan 196 spesies alga hijau, 134 spesies alga coklat, dan 452 alga merah. Sayangnya, meskipun terdapat banyak jenis rumput laut yang ditemukan diperairan Indonesia, baru sedikit jenis rumput laut yang diketahui memiliki nilai ekonomi tinggi. Padahal menurut FAO, rumput laut merupakan produk yang bisa dikembangkan menjadi makanan, kosmetika, farmasetika, bioetanol, pakan ternak, pakan ikan, aquakultur, dan penanganan limbah air. Rumput laut mengandung berbagai metabolit yang bermanfaat bagi manusia. Dibandingkan dengan rumput laut hijau dan coklat, rumput laut merah (Rhodopyta) merupakan jenis rumput laut yang paling banyak mengandung senyawa metabolit primer dan sekunder. Rumput laut merah dikenal sebagai penghasil phycocolloids seperti agarose, agar, karagenan, dan metabolit sekunder penting lainnya. Review ini bertujuan untuk memaparkan aktivitas-aktivitas biologi yang dimiliki alga merah sebagai bahan referensi berbagai bidang pemanfaatan alga.Kata kunci: Rumput laut, alga, Rhodophyta
