“…The antibacterial activity of ethanolic extract may be related to the high level of known components with antibiotic properties as phytol against E. coli, S. typhimurium, S. aureus, antifungicidal viz. C. albicans, A. niger [23][24][25][26]; squalene against S. aureus [27]; β-amyrin against B. subtilis, S. aureus, E. coli, S. typhimurium, in total they make up 15.44 % [28,29].…”

Gnaphalium uliginosum L. (Asteraceae) is widely used in phytotherapy and has a potential for agricultural utilization. The ethanolic extract was obtained from the maceration of air-dried plants, and the extract was then filtered and concentrated using a rotary evaporator. The essential oil was pressed from freshly harvested and crushed, aerial part of plants. The chemical compositions of ethanolic extract and essential oil of G. uliginosum L. (EOG) were investigated using gas chromatography/mass spectrometry (GC/MS). Nine constituents accounted for 77.3 % of the total detected components were determined at the ethanolic extract with a high proportion of sterols 42.8%, fatty acids 24.1 %, triterpenes 14.4 %. Twenty constituents were identified in essential oil of G. uliginosum L.; with α-pinene and estragole accounting for 54.0 %. The ethanolic extract was found to have a moderate antimicrobial activity (MIC values varied from 125 to 500 μg/mL), for S. aureus, B. cereus and A. solani significant activity (less than 62.5 μg/mL). The essential oil was found to have a moderate (MICs 500-1000 μg/mL) and strong activities (31.3-250 μg/mL). The antioxidant activity was evaluated using chemiluminescent assay. The ethanolic extract of G. uliginosum L. acted as a medium-strength antioxidant at concentrations of less than 0.1 mg/mL. The essential oil made be regarded as a weak strength antioxidant.

This paper is concerned with composition and antibacterial activities of ethyl acetate extracts from 3 species of Laurencia (Rhodophyta): Laurencia papillosa, Laurencia flexilis and Laurencia cartilaginea collected from the southern coasts of Vietnam. The results showed that ethyl acetate (EtOAc) extracts of these species displayed antibacterial activities against Salmonella typhimurium, Escherichia coli and Bacillus subtilis. The qualitative investigations revealed the presence of two sesquiterpene secondary metabolites Elatol and Palisadin A in EtOAc extracts from the three above- mentioned Laurencia species.

“…Previous studies discovered new antibacterial compounds from marine organisms such as algae, coral and sponge (Liu et al, 2014;Abdel-Raouf et al, 2015;Nguyen et al, 2017). Among all marine organisms, sponge is the most studied as source of bioactive compounds (Mehbub et al, 2014;Kumar and Pal, 2016).…”

Exploration of new source of antibiotics to combat multidrug-resistant bacteria is urgently needed. Indonesia as archipelago country has a wide variety of marine organisms with potential as source of new antibacterial compounds against MDRO. Aims of the study were to isolate sponge-associated fungi from sponge Cinachyrella sp. collected from Pandang Island, North Sumatera, Indonesia, to screen potential fungi against clinical pathogenic MDR bacteria, to identify the potential fungi; and to determine the best cultivation time for antibacterial production. Nine spongeassociated fungi were successfully isolated. Result of agar plug method showed fungus PDSP 5.7 was the most potential candidate which inhibited ESBL Escherichia coli, Salmonella enterica ser. Typhi, MRSA, and Staphylococcus haemolyticus strain MDR. This fungus had 100% similarity to Trichoderma reesei. In malt extract broth, T. reesei PDSP 5.7 had stationary phase from day 12 to day 18. In addition, the widest antibacterial was performed by extract from day 15. Furthermore, fungal extract showed best antibacterial activity against S. enterica ser. Typhi strain MDR with inhibition value of 14.72 ± 0.07 mm 2 .
