The majority of the textile dyes are harmful to environment and potentially carcinogenic. Among strategies for their exclusion, treatment dye contaminated wastewater with fungal extract, containing lignin peroxidase (LiP), may be useful. Two fungi isolates, Pleurotus ostreatus (PLO9) Ganoderma lucidum (GRM117), produced enzymatic extract by fermentation in lignocellulosic residue, Jatropha curcas seed cake. extracts from PLO9 GRM117 were immobilized on carbon nanotubes showed an increase 18...

New bioemulsifier-producing yeasts were isolated from the biological wastewater treatment plant of a dairy industry. Of 31 strains, 12 showed emulsifying activity after 2 months incubation, with E24 values ranging 7% to 78%. However, only Trichosporon loubieri CLV20, Geotrichum sp. CLOA40, and T. montevideense CLOA70 exhibited high emulsion-stabilizing capacity, 78%, 67%, 66%, respectively. These isolates shown induce strong emulsion stabilizing rather than reduction interfacial tension....

The COVID-19 pandemic highlighted the global necessity to develop fast, affordable, and user-friendly diagnostic alternatives. Alongside recognized tests such as ELISA, nanotechnologies have since been explored for direct indirect diagnosis of SARS-CoV-2, etiological agent COVID-19. Accordingly, in this work, we report a method detect anti-SARS-CoV-2 antibodies based on graphene-based field-effect transistors (GFETs), using nanostructured platform graphene with added gold nanorods (GNRs)...

Endophytic fungi represent large, yet unexplored components of biodiversity. This work evaluated the richness and distribution endophytes in leaves Bauhinia brevipes (Fabaceae). A total 1110 colonies were recovered from samples grouped by their morphological traits into 126 taxa. The number taxa according to leaf development was: 102 mature leaves, 93 recently expanded 79 for unfolded leaves. major endophyte genera Phomopsis, followed Dothiorella, Pestalotiopsis Acremonium. isolate numbers...

ABSTRACT Infection by nematode parasites with a pulmonary migration in their life cycle and allergic asthma are two highly prevalent diseases humans; therefore, one may expect both occur concomitantly. There is predominant essential role of Th2 lymphocytes the mechanisms underlying control parasite elimination as well pathology observed asthmatic lung. The consequences such situations have been explored, controversial results, justifying development experimental models which relationship...

Bradykinin (BK) appears to play an important role in the development and maintenance of inflammation. Here, we assessed BK B 2 receptor for injuries that occur after ischemia reperfusion (I/R) territory irrigated by superior mesenteric artery. Tissue (lung duodenum) kallikrein activity increased with greater enhancement reperfusion. A selective inhibitor tissue kallikrein, Phenylacetyl‐Phe‐Ser‐Arg‐ N ‐(2,3‐dinitrophenyl)‐ethylenediamine (TKI, 0.001–10 mg ml −1 ), inhibited a...

Abstract Aims To determine the frequency and diversity of yeasts from dorsum tongue necrotic root canals with teeth associated primary apical periodontitis. Methodology Detailed medical dental histories 168 patients were recorded. The samples collected contained pulps. Yeasts isolated on Sabouraud agar 100 mg L −1 chloramphenicol, purified characterized by standard methods. Identification was confirmed EI1 PCR fingerprint technique. Yeast isolates uncertain identity or a different genetic...

Four strains of an asexual arthroconidial yeast species were isolated from Drosophila flies in two Atlantic rain forest sites Brazil and oak tasar silkworm larvae ( Antheraea proylei ) India. Analysis the sequences D1/D2 large subunit rRNA gene showed that this represented a novel genus Geotrichum , described as silvicola sp. nov. The was related to ascogenous Galactomyces . closest relatives strain NRRL Y-6418 geotrichum type culture is UFMG-354-2 T (=CBS 9194 =NRRL Y-27641 ).

ABSTRACT The plasma level of the chemokine CCL3 is elevated in patients with chronic severe schistosomiasis mansoni. We have previously shown that −/− mice experimental infection showed diminished pathology and worm burden compared to those wild-type (WT) mice. To elucidate further role CC chemokines during mansoni infection, we evaluated course C57BL/6J deficient CCR5, one receptors for CCL3. CCR5 deficiency proved be remarkably deleterious host, since mortality rates reached 70% at 14...

SUMMARY Biomphalaria tenagophila of Taim strain is able to completely destroy Schistosoma mansoni sporocyst few hours after parasite penetration, although the mechanism still not well known. In this experimental work we show that passive transference cell‐free haemolymph, especially from B. Taim, resulted in higher resistance Cabo Frio S. infection. This effect was demonstrated vivo , by reduction infection rate, and significantly lower production sporocysts cercariae snails treated with...

In this study we evaluated the ability of Saccharomycopsis schoenii Nadson and Krassiln (UWO-PS 80-91) as biocontrol agent against plant pathogenic filamentous fungi P. expansum Link (UFMG 01-2002), italicum Wehmer (LCP 61.1199), digitatum (Pers.: Fr.) 984263, LCP 68175 4354). S. was able to reduce disease severity in oranges inoculated with all fungi. Among phytopathogens, LCP4354 most virulent whereas susceptible predation. The yeast survive for 21 days on fruit surface did not produce...

Helminth infection can reduce the severity of inflammatory bowel disease. However, modulatory mechanisms elicited by helminth are not yet fully understood and vary depending on experimental model. Herein we evaluated effect acute BALB/c mice with Strongyloides venezuelensis clinical course ulcerative colitis induced Dextran Sulfate Sodium (DSS) treatment these animals. For experiments, S. venezuelensis-infected were treated orally 4% DSS solution for seven days. As controls, used untreated...

Lactococcus lactis, the model lactic acid bacterium, is a good candidate for heterologous protein production in both foodstuffs and digestive tract. We attempted to produce Streptomyces tendae antifungal 1 (Afp1) L. lactis with objective of constructing strain able limit fungal growth. Since Afp1 activity requires disulfide bond (DSB) formation since intracellular redox conditions are reportedly unfavorable DSB prokaryotes, was produced as secreted form. An inducible expression-secretion...

We studied the yeast communities associated with fruits, mushrooms, tree exudates, and flies of genus Drosophila, in two Atlantic Rain Forest fragments state Minas Gerais, Brazil. A total 456 samples were collected from Rio Doce State Park 142 Ecological Station Universidade Federal de Gerais. From these samples, 608 isolates obtained, belonging to 71 different species. Among yeasts isolated Park, 17 recovered 12 13 299 Drosophila spp. In 24 fruits 243 Distinct observed flies, mushrooms...

Lectin-carbohydrate binding may be involved in the recognition of Schistosoma mansoni sporocysts by haemocytes Biomphalaria; therefore, we tested if this interaction is associated with snail resistance against infection. In vitro data showed that most S. cultured from Biomphalaria glabrata BH, a highly susceptible strain, had low number cells adhered to their tegument and mortality rate. Moreover, addition N-acetyl-D-glucosamine (GlcNAc) did not alter pattern adherence mortality. Using...
