The present work had the goal of screening a batch 20 fungal strains, isolated from sugar cane plantation soil, in order to identify those capable biosynthesis silver nanoparticles. These nanoparticles are known have large and effective application clinical microbiology. Four strains were found be biosynthesised characterised by UV–vis spectroscopy, scanning electron microscopy, EDX, XRD. They an average size 30–100 nm, regular round shape, potential antimicrobial activity against...
Abstract Covering a quarter of the world’s tropical coastlines and being one most threatened ecosystems, mangroves are among major sources terrestrial organic matter to oceans harbor wide microbial diversity. In order protect, restore, better understand these researchers have extensively studied their microbiology, yet few surveys focused on fungal communities. Our lack knowledge is even more pronounced for specific populations, such as ones associated with rhizosphere. Likewise, Red Sea...
Silver nanoparticles (AgNPs) are some of the most attractive nanomaterials for commercial applications, but they can also be a very challenging issue from point view cytotoxicity and phytotoxicity as agents that damage genetic information.
The supply of drinking water to meet human needs is a major challenge the 21st century. public when not treated properly can become focus action various pathogens. In this context, work addresses an exploratory and integrative literature review seeking articles that addressed metal nanoparticles synthesized by marine microorganisms for antimicrobial application in treatment. search was conducted using following engines: Scielo, Google Scholar, Portal Capes, Springer, Scopus® Reed Elsevier....
Twelve marine-derived fungal strains were evaluated for their ability to synthesize silver nanoparticles (AgNPs). Mycogenic AgNPs preliminarily characterized using different techniques, and antimicrobial activities assessed. Penicillium citrinum IBCLP11 Aspergillus niger IBCLP20 selected AgNPs’ synthesis optimization by varying parameters such as AgNO3 concentration, biomass, agitation, temperature, pH. AgNPIBCLP11 AgNPIBCLP20 able inhibit the growth of Pseudomonas aeruginosa IPT322,...
The marine environment is a rich source of new biotechnologies and products. Bottom trawling for shrimp species such as Xiphopenaeus kroyeri Farfantepenaeus brasiliensis leads to the unintentional capture non-target species, known bycatch, which includes variety life that are often discarded without economic value. A common bycatch on southeast coast Brazil Olivancillaria urceus (O. urceus), carnivorous gastropod feeds mainly bivalves. Despite its abundance, this still little studied,...
Fructooligosaccharides (FOS) are mainly produced by microbial fructosyltransferases (FTase, E.C.2.4.1.9), and Aspergillus oryzae IPT-301 has shown high fructosyl transferring low hydrolytic activities, which leads to FOS production yields, but the main operating parameters for its best performance have been scarcely studied. Thus, this work aimed evaluate cellular growth, characterization of mycelial extracellular FTases IPT-301. Experimental design showed that FTase was optimized (high...
β-Fructofuranosidase production by Aspergillus oryzae IPT301 was maximized in shake flasks. Response Surface Methodology (RSM) involving Small Central Composite Design adopted to evaluate the fructosyltransferase (FTase) activity changing three medium component concentrations: sucrose, urea and yeast extract. The optimal set of conditions for maximum as follows: sucrose 320.5 g/L, 7.13 g/L extract 2.11 g/L. In this condition, following improvements were achieved: an increase 48.8% cell...
To find effective silver nanoparticles (AgNPs) for control of phytopathogens, in this study, two strains actinomycetes isolated from the soil Brazilian biome Caatinga (Caat5-35) and mangrove sediment (Canv1-58) were utilized. The identified by using 16S rRNA gene sequencing as Streptomyces sp., related to mimosus species. obtained AgNPs coded 35 AgNPs58 characterized size morphology dynamic light scattering, zeta potential, transmission electron microscopy, Fourier transformed infrared...
Polygalacturonases (PG) are pectinolytic enzymes that have technological, functional and biological applications in food processing, fruit ripening plant-fungus interactions, respectively. In the present, a microtitre plate methodology was used for rapid screening of 61 isolates fungi from Aspergillus section Nigri to assess production endo- exo-PG. Studies scale-up were carried out fixed bed reactor operated under different parameters using best producer strain immobilised orange peels....
The capability of the fungi Nigrospora sp. CBMAI 1328 and Arthopyrenia 1330 isolated from marine sponge to synthesise laccases (Lcc) in presence inducer copper (1-10 μM) was assessed. In a liquid culture medium supplemented with 5 μM sulphate after days incubation, presented highest Lcc activity (25.2 U·L(-1)). effect on gene expression evaluated by reverse transcriptase polymerase chain reaction. showed under same conditions synthesis. detected at 96 h incubation absence copper. Molecular...
Silver nanoparticles (AgNPs) are widely incorporated into different hygiene, personal care, and healthcare products. However, few studies have been undertaken to determine the effects of biogenic AgNPs on human health. The effect biosynthesized using fungus Aspergillus tubingensis culture was evaluated umbilical vein endothelial cells (HUVECs), normal fibroblasts (FN1), hepatoma (HEPG2) a Galleria mellonella model. HUVECs were more susceptible than FN1 intense cytotoxicity observed only for...
