Abstract Ulva Lactuca and Sargassum sp. are rapidly expanding algae that can be used as a source of bioenergy. Due to its high moisture inorganic content, the direct use for energy purposes is deep. Therefore, thermochemical processing, such pyrolysis, required produce useful products, bio-oil. This study seeks undertake detailed investigation bio-oil production from provide information continu...

Packaged mineral water has become a daily necessity for Indonesians its practicality. The raw material used in container is made of plastic because the price cheaper, and characteristics it are strong lightweight when compared to other polymers. However, waste produced difficult be decomposed by microorganisms soil, causing environmental pollution. There have been many researches on production ...

Canopy-forming seaweeds, as primary producers and foundation species, provide key ecological services. Their responses to multiple stressors associated with climate change could therefore have important knock-on effects on the functioning of coastal ecosystems. We examined interactive effects of UVB radiation and warming on juveniles of three habitat-forming subtidal seaweeds from Western Austr...

Two of bioactive natural products were founded in a brown alga, Sargassum fulvellum. After isolation and purification, the molecular structures of these two products were investigated by NMR spectroscopy and GC-mass spectroscopy. The two compounds were identified to be 1-O-palmitoyl-2-O-oleoyl-3-O-(alpha-D-glucopyranosyl)-glycerol (POGG) and 1-O-myristoyl-2-O-oleoyl-3-O-(alpha-D-glucopyranosyl)...

The purified total sterols and β-sitosterol extracted from Sargassum horneri were evaluated for their antidepressant-like activity using the forced swim test (FST) and tail suspension test (TST) in mice. Total sterols and β-sitosterol significantly reduced the immobility time in the FST and TST. Total sterols were administered orally for 7 days at doses of 50, 100, and 200 mg/kg, and β-sitoster...

This work reported on the in vitro antibacterial activity of six selected marine algae (seaweeds) which have been selected and their extracts have been tested as an alternative to commonly used antibiotics. Extracts of six seaweed samples namely Codium decorticatum, Caulerpa scalpelliformis, Gracilaria crassa, Acanthophora spicifera, Sargassum wightii and Turbinaria conoides were collected from...
