Resistance to pathogenic bacteria may lead to serious health problems. Scientists found that discovering novel antimicrobial compounds is possible by exploring rarely investigated environments. Therefore, this work focused on isolating and identifying some fungal strains collected from the Co To sea. We tested whether such strains can produce compounds with vital activities, including antibacterial and antifungal. The antimicrobial activity of the marine fungi crude extracts was performed by the Bioassay method in a 96-well tray.

This study aimed to isolate and identify marine fungi from Bai Tu Long Bay and assess their antimicrobial potential. We successfully isolated twenty strains of marine-derived fungi. The crude extracts from these fungi were tested against pathogenic microorganisms. All twenty strains exhibit some degree of growth inhibition against the tested microorganisms.

This study implicated the soft coral-associated Micrococcus sp. strain A-2-28 (following relative Micrococcus flavus LW4T) for large-scale cultivation, chemical analyses, and biological activities. Whereas crude extract of the strain A-2-28 inhibited only Staphylococcus epidermidis, metabolites profiles and pure compounds from strain A-2-28 showed that this strain produced phytohormone (IAA), metabolized some new compounds which were almost inactive for biological tests.

Zoanthid is a potential natural resource with many biological activities, such as antioxidant, antiviral, antiinflammatory, and cytotoxic activity. Therefore, this study aimed to evaluate the antioxidant activity of 70% ethanol crude extract and dichloromethane fraction from Zoanthus vietnamensis. The total polyphenol content of ethanol and dichloromethane extracts were 19.36 ± 1.37 and 24.95 ± 0.63 mg GAE/g extract, respectively.

Ebook "NMR-bioassay guided isolation of the natural 20S proteasome inhibitors from photorhabdus luminescens: A novel NMR-tool for natural product detection" describes a novel methodology for natural product discovery. Due to its high degree of reproducibility, robustness and sensitivity, the technique can be utilized to detect even trace amounts of bioactive substances in heterogeneous matrices such as fermentation broths or crude organic extracts.

Plants of the genus Polyscias (the family Araliaceae) are represented as perennial shrubs and are commonly cultivated in southeastern Asia and the Pacific regions. Pharmacological studies revealed that Polyscias crude extracts and their isolated compounds exhibited a variety of biological activity, such as antibacterial, antifungal, cytotoxic, immunostimulant, wound healing and anti-asthmatic activities.

The chemical composition, antioxidant properties and antibacterial activities of different extracts (water, ethanol, acetate ethyl and hexane) and essential oil from Platycladus orientalis leaves were analysed in this study. The essential oil was extracted by hydrodistillation, and its chemical composition was determined by gas chromatography coupled to mass spectrometry (GC-MS).

IgE reactivity to fish allergens in atopic dogs, which are used as models for food allergy, has not been elucidated to date. We investigated IgE reactivity to crude extracts and purified allergens derived from the Pacific cod (Gadus macrocephalus) in atopic dogs to identify the allergenic proteins of cod.

The crude enzyme extract of the strain was also characterized the activity with respect to temperature, pH, incubation period and two different enzyme substrates. High protease activity produced by Bacillus sp. B9 was observed at 36h of incubation at 45 oC with the initial pH of 9.0 by using gelatin as its substrate. Additionally, when using gelatin substrate, the protease activity was much higher than in the case of casein.

The effect of the crude oils of the produced black cumin seeds on some human pathogenic bacteria was studied. It was found that the crud fixed oil extracted from the seeds of plants has powerful antibacterial properties against this diverse genus of bacteria. However, the influence was different and depending on the tested bacterial strain.

The venom of two dominant species of wolf spiders, Pardosa sumatrana Thorell and Pardosa birmanica Simon, was extracted and characterized. Insecticidal potential of crude venom and selected peptide fractions (i.e. 35-kDa fraction of both spiders) was evaluated in the laboratory using Rhopalosiphum padi (Linnaeus) (Homoptera: Aphididae) as a model pest. Results of the study showed that both the crude venom and the protein fractions caused significantly higher mortality in treated aphids compared to the control.
