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 airborne As...

We studied human mycoses in conjunctiva, nails (onycholytic lesions) and skin lesions in 100 babaçu coconut breakers of Esperantinópolis, Maranhão (Fig. 1), and studied the ground near the babaçu palms, coconut shells and palm leaves (Fig. 2), for taxonomic classification of fungi by direct mycological and microscopic examination. We also performed direct examination with KOH for human mycoses....

The aim of the study was investigate antifungal activity of the various leaves extracs of Achyranthes aspera Linn.The aqueous,ethanol and methanol leaves extracts of Achyranthes aspera Linn. (Family:Amaranthaceae) were evaluated for antifungal activity against clinically important fungal spp viz. Candida albicans (MTCC 227), C.tropicalis (MTCC 750), C.krusei (ATCC 6258), C.kefyr (ATCC 4235), C....

Orange peel extract solution contains mucilage flavor and three types of glycosides. Limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. As it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. In the present study the effects of orange extract and two types of limon...

BACKGROUND Carissa opaca Stapf ex Hanes fruits is traditionally used in the treatment of asthma, hepatitis and microbial infections. The present study was arranged to investigate the antimicrobial, cytotoxic and antitumor activity of various fractions of C. opaca extract and its bioactive metabolites responsible for that activity. METHODS To characterize various fractions of C.opaca antibacte...

We investigated the in vitro interaction of terbinafine with itraconazole, fluconazole, amphotericin B and 5-flucytosine, against Aspergillus spp. We tested three isolates of Aspergillus fumigatus (one resistant to itraconazole), and two each of Aspergillus flavus, Aspergillus niger and Aspergillus terreus. We employed a broth microdilution-based method derived from an in vivo validated method ...

The faeB gene encoding a second feruloyl esterase from Aspergillus niger has been cloned and characterized. It consists of an open reading frame of 1644 bp containing one intron. The gene encodes a protein of 521 amino acids that has sequence similarity to that of an Aspergillus oryzae tannase. However, the encoded enzyme, feruloyl esterase B (FAEB), does not have tannase activity. Comparison o...

Fungi involved in the biodegradation of maizecob were isolated and screened for cellulase activity using glucose and carboxylmethyl cellulose as carbon sources. The effect of the carbon sources on cellulase production was determined. Eleven fungi species were isolated which include Rhizopus oryzae, Aspergillus flavus, Mucor racemosus, Aspergillus niger, Penicillium atrovenetum, Penicillium expa...
