The present study focuses on potential agents of chromoblastomycosis and other endemic diseases in the state Paraná, Southern Brazil. Using a highly selective protocol for chaetothyrialean black yeasts relatives, environmental samples from living area symptomatic patients were analysed. Additional strains isolated creosote-treated wood hydrocarbon-polluted environments, as such polluted sites have been supposed to enhance yeast prevalence. Isolates showed morphologies compatible with...
Data are presented on the clinically relevant black yeasts and their relatives, i.e., members of Ascomycete order Chaetothyriales. In to understand pathology these fungi it is essential know natural ecological niche. From a relatively low degree molecular variability yeast Exophiala dermatitidis, potential agent brain infections in patients from East Asia, concluded that this species an emerging pathogen, currently going through process active speciation. It found be oligotrophic fungus hot,...
The genus Fonsecaea is revised on the basis of ribosomal DNA internal transcribed spacer (ITS) sequence data. Two species are recognized, F. pedrosoi and new defined monophora. distinction between these does not correspond with classical compacta. latter appears to be no more than a morphological variant. Both recognized in this study agents human chromoblastomycosis; however, strict association disease noted, while monophora general opportunist. Subspecific randomly amplified polymorphic...
Black yeast members of the Herpotrichiellaceae present a complex ecological behavior: They are often isolated from rather extreme environments polluted with aromatic hydrocarbons, while they also regularly involved in human opportunistic infections. A selective technique to promote vitro growth herpotrichiellaceous fungi was applied investigate their ecophysiology. Samples natural niches and man-made that might contain black yeasts were enriched on an inert solid support at low humidity...
The oil flotation isolation technique has been successfully applied to recover chaetothyrialean black yeasts and relatives from the environment.The selective mechanisms playing a role in are unknown.The fungi concerned supposed occupy specialized microniches nature, taking advantage of (1) oligotrophism.Mineral as main agent may be based on (2) hydrophobicity or (3) assimilation.All three hypotheses tested this paper.Results show that cell wall is unlikely factor.Incubation under poor...
Bacteria exhibiting beneficial traits like increasing the bioavailability of essential nutrients and modulating hormone levels in plants are known as plant growth promoting (PGP) bacteria. The occurrence this specific group bacteria endophytic environment may reflect decisive role they play a particular condition. This study aimed to determine taxonomical diversity culturable bacterial endophytes, isolated vegetative stage passionflower ( Passiflora incarnata ), assess its potential promote...
Abstract This research investigated active biomolecules from the endophytic fungus Aspergillus unguis (CBMAI 2140), isolated Passiflora incarnata leaves, as potential antibacterial agents against Xanthomonas citri subsp. citri, causative agent of citrus canker. The fungal extract was obtained via liquid-liquid extraction with ethyl acetate. Antibacterial activity assessed using Resazurin Microtiter Assay Plate (REMA), determining inhibitory concentrations (IC90) and Minimum Bactericidal...
While many members of the black yeasts genus Cladophialophora have been reported to cause diseases in humans, understanding their natural niche is frequently lacking. Some species can be recovered from environment by means selective isolation techniques. The present study focuses on a strain that caused an interdigital tinea nigra-like lesion HIV-positive Brazilian child. fungal infection was successfully treated with oxiconazole. Similar strains had Brazil, Uruguay and Netherlands. were...
Ochroconis globalis, a novel species of the melanized genus (Sympoventuriaceae, Venturiales), is described and illustrated distinguished phenotypically molecularly from existing ochroconis-like species. Phylogenetic analyses using nuclear ribosomal DNA genes (nuSSU, ITS, nuLSU) coding gene fragments (ACT1, BT2, TEF1) revealed clustering all strains as monophyletic clade which was well separated known Most new were obtained human-made environments, while natural habitat remains enigmatic. The...
Fonsecaea and Cladophialophora are genera of black yeast-like fungi harboring agents a mutilating implantation disease in humans, along with strictly environmental species. The current hypothesis suggests that those species reside somewhat adverse microhabitats, pathogenic siblings share virulence factors enabling survival mammal tissue after coincidental inoculation driven by adaptation. A comparative genomic analysis was undertaken, including de novo assembly F. erecta from plant material....
Abstract Plants and endophytic microorganisms have coevolved unique relationships over many generations. show a specific physiological status in each developmental stage, which may determine the occurrence dominance of populations with predetermined ecological role. This study aimed to compare structure composition cultivable uncultivable bacterial communities vegetative reproductive stages (RS) Passiflora incarnata . To that end, were assessed by plating Illumina‐based 16S rRNA gene...
Environmental pollution with alkylbenzene hydrocarbons such as toluene is a recurring phenomenon. Their toxicity and harmful effect on people the environment drive search for sustainable removal techniques bioremediation, which based microbial metabolism of xenobiotic compounds. Melanized fungi present extremophilic characteristics, allow their survival in inhospitable habitats those contaminated hydrocarbons. Screening methodologies testing assimilation volatile organic compounds (VOC) are...
Approximately 400 billion PET bottles are produced annually in the world, of which from 8 to 9 million tons discarded oceans. This requires developing strategies urgently recycle them. recycling can be carried out using microbial hydrolysis polymers when monomers and oligomers released. Exploring metabolic activity fungi is an environmentally friendly way treat harmful polymeric waste obtain production monomers. The present study addressed: (i) investigation potential strains with for...
The Atlantic Rainforest is a Brazilian ecosystem that being rapidly destroyed, along with the abiotic and biotic factors present in it. Among factors, fungi are found soil which, besides of major importance terms ecological niches, also have broad significant applications biotechnology. In order to assess biodiversity these microorganisms this type ecosystem, Banhado Grande region was chosen at Juréia-Itatins Ecology Station, state São Paulo, Brazil. Within region, two areas were delimited...
Amplicons of SSU and ITS1+2 rDNA 13 strains Fonsecaea pedrosoi three F. compacta were digested with seven restriction enzymes. In addition, the ITS1 region 14 was sequenced. With both methods significant variation found which, however, did not coincide established species limits based on morphology.
This study provides a comparison of fermentation conditions for the production lipases by Fusarium sp. ( Gibberella fujikuroi complex) isolate FCLA‐MA‐41 in submerged (SmF) and solid‐state (SSF) using agro‐industrial residues. To assess SmF, univariate seven carbon sources (crambe, corn, linseed, olive, palm (dendê), soybean oils chicken fat) four nitrogen (ammonium sulfate, sodium nitrate, urea, yeast extract) was performed. The relationship among concentrations sources, Triton X‐100...
Isolates of Teratosphaeriaceae have frequently been found in the integument attine ants, proving to be common and diverse this microenvironment. The LSU phylogeny ant-isolated strains studied revealed that they cluster two main lineages. first was associated with genus Xenopenidiella whereas other represented lineages sister taxa Penidiella aggregata P. drakensbergensis, which are allocated new Penidiellomyces. is limited lineage containing columbiana, not congeneric Penidiellomyces or...
