Ruta graveolens L. is an herbal plant which is traditionally used as an energizer and an anti-bleeding to heal injuries. Regarding increasing prevalence of mycotoxins and inefficiency of methods used to decrease them, it is possible to use plants metabolites to decrease mycotoxins. The antifungal effect of Ruta graveolens on Aspergillus flavus and Penicillium sp. in vitro by disk and well diffu...

The soil samples were collected and were primarily screened for isolation of amylase producing fungi. Among the isolated fungi, amylase producing isolates were identified by growing on starch agar media. The isolates exhibiting the maximum zone of clearance on starch agar media by iodine were identified and were subcultured on potato dextrose agar (PDA). The isolates were morphologically charac...

The present study is concerned with the production of glucose oxidase (GOD) from thermophilic Penicillium sp. in a 250 mL shake flask. Fourteen different strains of thermophilic Penicillium sp. were isolated from the soil and were screened for glucose oxidase production. IIBP-13 strain gave maximum extra-cellular glucose oxidase production as compared to other isolates. The effect of submerged ...

The effect of two fungicides, Caocobre and Ridomil on rhizosphere phenomenon of Cocoa (Theobroma cacao L) seedlings has been studied at different stages of the development of the plant growing in pots. Fungal population in the rhizophere soil was generally higher than in the non-rhizosphere soil. The total number of fungal population in both the rhizosphere and non-rhizosphere was highest on th...

A 71-year-old man with interstitial pneumonia was hospitalized due to a pulmonary infection. He had been living in Thailand and had returned to Japan three months earlier. Antibiotic therapy initially cleared the infection; however, the patient's condition relapsed. Pseudomonas aeruginosa and Penicillium sp. were both detected in sputum and bronchial lavage fluid cultures and Penicillium sp. wa...

Acid- and aluminum (Al)-tolerant microorganisms were isolated from tea fields, from which six strains were selected and identified as Cryptococcus humicola, Rhodotorula glutinis, Aspergillus flavus Link, Penicillium sp., Penicillium janthinellum Biourge and Trichoderma asperellum. They were tolerant to Al up to 100-200 mM and could grow at low pH, 2.5-2.2. In a glucose medium (pH 3.5) the pH of...

sugar beet roots and attached soil are usually transferred to sugar factories for processing ,then the roots are washed by pressurized water. muddy water as waste flows in canal and is used to irrigate fields. the possibility of occurrence and fluctuations of the pathogenic organisms in waste were studied in 2005. the samples were collected from waste water once a week. isolation of pathogens w...

BACKGROUND AND OBJECTIVES Evaluation of contamination of anesthesia circuits by collecting 56 culture samples from the circular system; previously reprocessed tracheas by disinfection with 1% hypochlorite or 2% glutaraldehyde after being washed in non-sterile water and soap and dried by using compressed air and stored in surgical grade paper; and from other places of the non-reprocessed respira...

A marine Ascidian-associated fungus, Trichoderma harzianum, (NIO/BCC2000-51) was assessed for its in vitro antagonistic activity against ten fungal phytopathogens and three food-infesting fungi. Fractionation of the cell-free culture filtrate of T. harzianum (NIO/BCC2000-51) showed its ethyl acetate (EA) fraction to be significantly active against fungal phytopathogens; Macrophomina sp, Pyricul...

Although numerous studies have been conducted on microbial contaminants associated with various stages related to poultry and meat products processing, only a few reported on fungal contamination of poultry litter. The goals of this study were to (1) characterize litter fungal contamination and (2) report the incidence of keratinophilic and toxigenic fungi presence. Seven fresh and 14 aged litt...
