Moulds constitute the largest group of bacteria, prevailing both in the indoor and outdoor air. Approximately 200 000 species of moulds have been identified so far, where only a small group of around 200 may present a threat to human health. Fungi from Aspergillus species are among the moulds considered to be most pathogenic. They also constitute the group of most pathogenic moulds most frequen...

background and objectives: essential oils (eos) possess a wide range of significant properties including antiphlogistic, spasmolytic and antinociceptive effects. in this study, we use eos from thymus daenensis, thymus caramanicus and ziziphora clinopodiodes. materials and methods: in this study, the plants were collected from the botany department, were air dried, grinded and set for extraction...

background & aim: in recent years using from plant product has been considered wildly as main factor for preventing pathogenic diseases cassed by attacking viruses, bacteria, fungi and parasites. there are some funguses which could be the factors for affliction of some diseases in human, plants and animals. plant extracts are those which could act and be used as preventing from these diseas...

A number of species belonging to the genus Aspergillus were evaluated for their toxicity to ducklings and the ability to produce sterigmatocystin. Three new species capable of producing sterigmatocystin were found, namely, Aspergillus aurantio-brunneus, Aspergillus quadrilineatus, and Aspergillus ustus. All three were toxic to ducklings. The production of sterigmatocystin by Aspergillus rugulos...

Knowledge of the mechanisms of action of biocontrol agents (BCAs) is crucial to identify underlying pivotal traits, whose enhancement could boost antagonist activity and encourage the use of BCAs as alternative/integration of fungicides. We had previously shown that resistance of postharvest BCAs to oxidative stress is a possible key mechanism for their wound competence to successfully outcompe...

paddy straw is one of the most abundant agricultural by-products in tamil nadu, india. itcontains high amounts of cellulose and lignin. the fungal strains were isolated from naturally decomposingsites of paddy straw. eight fungal strains were isolated and later these eight fungi were used for finding outtheir potential for the degradation of lignin and cellulose content of paddy straw. among ei...

aspergillus species (a flavus and a niger) are important sources of inhalant allergens. current  diagnostic  modalities  employ  crude  aspergillus  extracts  which  only  indicate  the source to which the patient has been sensitized, without identifying the number and type of allergens in crude extracts. we report a study on the identification of major and minor allergens of the two common air...

PHB degradation capabilities of seven species of Aspergillus namely Aspergillus niger, Aspergillus flavus, Aspergillus ochraceus, Aspergillus nidulans, Aspergillus terreus, Aspergillus fumigatus and Aspergillus parasiticus on the polymer produced by Rhodospseudomonas palustris KU003 were assayed . Among all the fungi investigated, the ability of A.niger to utilize the biopolymer was the highest...

Fungal species of the genus Aspergillus play significant roles as model organisms in basic research, as "cell factories" for the production of organic acids, pharmaceuticals or industrially important enzymes and as pathogens causing superficial and invasive infections in animals and humans. The release of the genome sequences of several Aspergillus sp. has paved the way for global analyses of p...
