background: it has been shown that zinc has an effect on physiological responses in animals and birds. on the other hand, dietary phytase in poultry results in increased availability of zinc. objectives: this study was conducted to investigate the effects of zinc oxide (zno) and escherichia coli-derived 6-phytase supplemented diets on the plasma metabolites and enzyme activities of broiler bree...

Lichens are valuable natural resources used for centuries throughout the world as medicine, food, fodder, perfume, spices and dyes, as well as for other miscellaneous purposes. This study investigates the antiproliferative, antibacterial and antifungal activity of the acetone extract of the lichen Xanthoria parietina (Linnaeus) Theodor Fries and its major secondary metabolite, parietin. The ext...

AIMS Four well-described strains of Pseudomonas fluorescens were assessed for their effect on pea growth and their antagonistic activity against large Pythium ultimum inocula. METHODS AND RESULTS The effect of Pseudomonas strains on the indigenous soil microflora, soil enzyme activities and plant growth in the presence and absence of Pythium was assessed. Pythium inoculation reduced the shoot...

Scorodonin (1), a novel biologically active metabolite, was isolated from submerged cultures of the mushroom Marasmius scorodonius (FR.) FR. Its structure has been determined by chemical and physical methods. The antibiotic inhibits the growth of bacteria, yeasts, and filamentous fungi. In cells of the ascitic form of EHRLICH carcinoma the incorporation of thymidine and uridine into DNA and RNA...

Actinomyces strain A01 was isolated from soil of a vegetable field in the suburb of Beijing, China. According to the morphological, cultural, physiological and biochemical characteristics, and 16S rDNA sequence analysis, strain A01 was identified as Streptomyces lydicus. In the antimicrobial spectrum test strain A01 presented a stable and strong inhibitory activity against several plant pathoge...

Xestoquinone and related metabolites (the xestoquinone family) occur in marine sponges and are known to show a variety of biological activities. In this study, the first comprehensive evaluation of antifungal activity was performed for xestoquinone and nine natural and unnatural analogues in comparison with their cytotoxicity. The cytotoxicity against two human squamous cell carcinoma cell line...

this study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. two hundred and seven days old arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (ssb); 3) basal diet + 1% non-processed sodi...

Three sections of Aspergillus (five species, 21 strains) were classified according to culture medium-dependent and time-dependent secondary metabolite profile-based chemotaxonomy. Secondary metabolites were analysed by liquid chromatography-electrospray ionisation tandem mass spectrometry (LC-ESI-MS-MS) and multivariate statistical methods. From the Aspergillus sections that were cultured on ma...

The antifungal activity of the sesquiterpenoids (+)-curcuphenol and (+)curcudiol isolated from the Caribbean sponge Didiscus oxeata was evaluated against several filamentous fungi.

Fungal infection is one of the diseases that has experienced an increasing incidence in world, especially Indonesia with its geographical condition as a country tropical climate high temperature and humidity. One most common fungal infections caused by fungus Candida albicans. The antifungal resistance become health problem increase mortality. Efforts must be made to overcome this utilizing sec...
