The main problem when treating industrial wastewater is the removal of dyes. Some of the physical and chemical treatment techniques were effective but they might result in the production of toxic by-products and could also be the cause of a secondary pollution problem due to excessive chemical use. In order to overcome the drawbacks, the present work has focused on the biodegradation of dyes us...

Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...

BACKGROUND The fungus Aspergillus fumigatus, whose spores are present ubiquitously in the air, causes a range of diseases in the human lung. A small molecular weight (< 10 kD) heat stable toxin released from the spores of clinical and environmental isolates of A fumigatus within minutes of deposition in aqueous solution has previously been described. A key effect of the toxin was to inhibit the...

Xylocarpus granatum produces various bioactive compounds with diverse biological activities, one of them as an antioxidant. Endophytic actinobacteria can also produce compounds. This study aimed to explore the existence endophytic X. fruit and determine its antioxidant activity. The research method was carried out by isolating from using selective media Humic Acid (HV). Furthermore, characteriz...

Conditions are described that led to the isolation of NRRL B-2309M, a strain of Bacillus popilliae which sporulates regularly in laboratory culture. Colonies grown on a medium formulated with yeast extract and the ingredients of Mueller-Hinton with phosphate, trehalose, and agar, produced 20% spores in 10 to 12 days. The quantity and kind of yeast extract determine the extent of sporulation, al...

Entomopathogenic bacteria Xenorhabdus spp. produce secondary metabolites with potential antimicrobial activity for use in agricultural productions. This study evaluated the inhibitory effect of X. nematophila TB culture on plant pathogens Botrytis cinerea and Phytophthora capsici. The cell-free filtrate of TB culture showed strong inhibitory effects (>90%) on mycelial growth of both pathogens. ...

In the course of screening for novel naturally occurring fungicides from mushrooms in Yunnan province, China, the ethanol extract of the fruiting bodies of Albatrellus dispansus was found to show antifungal activity against plant pathogenic fungi. The active compound was isolated from the fruiting bodies of A. dispansus by bioassay-guided fractionation of the extract and identified as grifolin ...
