Inhibiting the growth of mold fungi on cellulose-based building materials may be achievable through the use of azole-based antimycotics. Azoles were variably effective against mold fungi that are frequently found on wood and wood products. Unseasoned southern yellow pine specimens that were dip-treated with varying concentrations of eight azoles were evaluated for their ability to resist mold i...
Soil is considered as the most complex media of microbial inhabitants including fungi. Soils differ in chemical composition and support the growth of specific fungal flora, however, majority of the soil fungi are autochthonous being indigenous to soil environment. Some of the soil fungi are associated with human and animal diseases and cause chronic problems. The soil containing keratin materia...
Background : Fungal respiratory infections are being recognized with increasing frequency in parallel with an expanding population of immunocompromised patients. In the present study 347 patients including 155 females and 192 males with suspected respiratory fungal infection were included. Materials and methods : Bronchial alveolar lavage, bronchial brushing, and biopsies from chest wall, lungs...
In the indoor environment, people are exposed to several fungal species. Evident dampness is associated with increased respiratory symptoms. To examine the immune responses associated with fungal exposure, mice are often exposed to a single species grown on an agar medium. The aim of this study was to develop an inhalation exposure system to be able to examine responses in mice exposed to mixed...
BACKGROUND Allergy to airborne fungi can cause rhinitis and severe asthma, hence the exposure to spores inside home is an important factor of sensitization. The aim of this study was to determine the distribution and prevalence of species of Alternaria, Aspergillus, Cladosporium and Penicillium inside and outside of homes of patients allergic to fungi and to evaluate seasonal variations. METH...
The potential of Calendula officinalis water extract against fungi Aspergillus niger and Penicillium sp. the effect addition on quality wheat bread were investigated. In vitro, reduced mycelial growth biomass production A. niger, but there was no inhibitory Enriched showed significantly higher total phenolic content, by about 77% 95% in bread, which 10% 15% replaced with extract, respectively. ...
In present investigation the biological leaching of aluminum by isolated fungi from red mud, the main waste product of the alkaline extraction of Al from bauxite was studied. Biological leaching experiments were carried out using indigenous, date and orange specimen fungi, Aspergillus Niger, Penicillium simplicissimum notatum. Savored Dextrose chloramphenicol Agar (SDA) wa...
The aim of the present work was focused on the cellulase production by Aspergillus niger using different substrates (i.e) rice bran, wheat bran, black gram bran, coconut oil cake, groundnut oil cake, and gingely oil cake. Solid state fermentation holds tremendous potentials for the production of the enzyme cellulase by Aspergillus niger. These agro industrial residues are cheap raw materials fo...
Aspergillus species (Fig. 1) are conidia-forming fungi that are responsible for a wide spectrum of human illnesses. About 19 species of Aspergillus have been documented as agents of human disease, but the majority of infections are caused by Aspergillus fumigates (Fresenius, 1850), Aspergillus flavus (Link,1809), Aspergillus niger (Van Tieghem, 1867), and Aspergillus terreus (Thom, 1918) [1, 2]...
Biology and ecology of mycotoxigenic Aspergillus species as related to economic and health concerns.
The fungal genus Aspergillus was established in 1729, and includes species that are adapted to a wide range of environmental conditions. Many aspergilli produce mycotoxins in foods that may be toxic, mutagenic or carcinogenic in animals. Most of the Aspergillus species are soil fungi or saprophytes but some are capable of causing decay in storage, disease in plants or invasive disease in humans...
