Exploring fungal bioemulsifiers: insights into chemical composition, microbial sources, and cross-field applications.

The demand for emulsion-based products is crucial for economic development and societal well-being, spanning diverse industries such as food, cosmetics, pharmaceuticals, and oil extraction. Formulating these products relies on emulsifiers, a distinct class of surfactants. However, many conventional emulsifiers are derived from petrochemicals or synthetic sources, posing potential environmental and human health risks.

The essential oil of the leaves of Verbesina macrophylla (Cass.) S.F.Blake has antimicrobial, anti-inflammatory and antipyretic activities and is toxicologically safe.

Ethnopharmacological Relevance: Verbesina macrophylla (Cass.) S.F.

Comparison of phenolic compounds, antioxidant and cytotoxic activity of extracts prepared from Japanese quince (Chaenomeles japonica L.) leaves.

Phenolic compounds are very important in the prevention and treatment of many civilization diseases, including colorectal cancer (CRC). In the present study we investigated and compared the phytochemical composition, antioxidant and cytotoxic activity of Japanese quince (Chaenomeles japonica L.) leaves crude phenolic extract (CPE) and purified phenolic-rich extracts (PRE).

Chemical composition and evaluation of the antinociceptive, antioxidant and antimicrobial effects of essential oil from Hymenaea cangaceira (Pinto, Mansano & Azevedo) native to Brazil: A natural medicine.

Ethnopharmacological Relevance: Hymenaea cangaceira Pinto, Mansano & Azevedo (Fabaceae) is a Brazilian medicinal plant widely known as "Jatobá". In folk medicine, it is used to treat infections, respiratory problems, rheumatism, antitumoral, inflammation and pain, however, no activity has been scientifically validated.

Aim Of The Study: This study investigated chemical composition of essential oil from Hymenaea cangaceira (EOHc), antimicrobial, antinociceptive and antioxidant activities besides protection against DNA damage and hemolysis.

A New Salt-Tolerant Thermostable Cellulase from a Marine sp. Strain.

A salt-tolerant cellulase secreted by a marine sp. SR22 strain with wide resistance to temperature and pH was purified and characterized. Its approximate mass was 37 kDa.

Production of rhamnolipids and diesel oil degradation by bacteria isolated from soil contaminated by petroleum.

Biosurfactants are microbial secondary metabolites. The most studied are rhamnolipids, which decrease the surface tension and have emulsifying capacity. In this study, the production of biosurfactants, with emphasis on rhamnolipids, and diesel oil degradation by 18 strains of bacteria isolated from waste landfill soil contaminated by petroleum was analyzed.

The influence of fish culture in floating net cages on microbial indicators of water quality.

This work was carried out to analyse the microbiological parameters of the water quality of a reservoir used for the irrigation and culture of tilapia (Oreochromis niloticus) in floating net cages. The physico-chemical parameters, counts of mesophilic total aerobic bacteria, total and thermotolerant coliforms and fecal streptococci, and the presence of Escherichia coli in samples of water collected in three sites of the reservoir (pre-culture site, culture site, post-culture site) were analysed. The levels of ammonia (0.

Antagonistic activity of bacteria isolated from crops cultivated in a rotation system and a monoculture against Pythium debaryanum and Fusarium oxysporum.

The effect of crop rotation and monocropping on the occurrence of bacteria with antagonistic activity toward Pythium debaryanum and Fusarium oxysporum was shown. Arthrobacter spp., fluorescent Pseudomonas spp.
