Citrinin is one of the mycotoxins produced by Penicillium citrinum. We examined the decomposition products after heating citrinin in water at 140 degrees C and isolated a major product, citrinin H2 (3-(3,5-dihydroxy-2-methylphenyl)-2-formyloxy-butane). Citrinin H2 did not show significant cytotoxicity to HeLa cells up to a concentration of 200 microg/ml (% cytotoxicity: 39%) in 63 h of incubati...

This study explored the application of radio frequency (RF) energy in conjunctionwith conventional hot air treatment to provide uniformheating for control ofmold in pre-packaged bread loaf. A 6 kW, 27.12 MHzRF system was...

fungal infections of fish are widespread problem which affect wild and farmed species. the aim of the present study was to isolate and identify fungal flora in cultivated and natural caspian sea acipenser persicus. the samples were obtained from skin, fin and gill of the fish and were inoculated into culture media with antibiotics and incubated at 23±1 ?c. 13 species of fungi isolated from the ...

Riddle, H. F. V. (1974). British Journal of Industrial Medicine, 31, 31-35. Prevalence of respiratory symptoms and sensitization by mould antigens among a group of maltworkers. The prevalence of allergic alveolitis, chronic respiratory symptoms, and sensitization by antigens from mould spores was investigated in 114 men employed at five maltings. Twentyfive carpet workers were used as a control...

Produksi jagung di Provinsi Lampung hingga saat ini belum mampu mencapai produksi optimum jagung. salah satu kendala dalam upaya peningkatan adalah adanya serangan hama invasif Spodoptera frugiperda. Hama mengakibatkan kerusakan yang parah sehingga berdampak pada penurunan hasil. Pengendalian S. frugiperda dilakukan dengan aplikasi insektisida. Namun penggunaan insektisida intensif dapat memicu...

Seed health testing by studying the seed-borne fungi of soybean seeds is an important step in the management of the seed-borne diseases. In the present study seed-borne fungi was studied by using agar plate method. A number of seed-borne fungal species was isolated from the agar plate. These seed-borne fungal sps. were Aspergillus niger, A. flavus, A. fumigatus, Chaetomium globosum, Curvularia ...

Penicillolysin is a member of the clan MX and the family of M35 proteases. The enzyme is a thermolabile Zn(2+)- protease from Penicillium citrinum with a unique substrate profile. We expressed recombinant penicillolysin in Aspergillus oryzae and generated several site-directed mutants, R33E/E60R, A167E and T81P, with the intention of exploring thermal stabilization of this protein. We based our...
