Interaction among and between mushroom / white rot and brown rot fungi or soft rot fungi, studied by the dual culture plate assays showed that the outcome of a specific interaction was strongly dependent on the two organisms concerned. Phanerochate chrysosporium as one of the partner in dual cultures, invariably scored grade 2 for colony interaction as it overgrew and covered the colony of othe...

Fungal laccases are involved in a variety of physiological functions such as delignification, morphogenesis, and parasitism. In addition to these functions, we suggest that fungal laccases are involved in defense mechanisms. When the laccase secreting Trichoderma viride was grown in the presence of a range of microorganisms including bacteria and fungi, laccase secretion was enhanced in respons...

The genome of Paenibacillus polymyxa Sb3-1, a strain that shows antagonistic activities against pathogenic fungi and bacteria, consists of one 5.6-Mb circular chromosome and two plasmids of 223 kb and 8 kb. The genome reveals several genes that potentially contribute to its antagonistic and plant growth promotion activity.

Evaluation of the efficacy of blue-green algal compounds against the growth of either pathogenic or antagonistic microorganisms as well as their effect on the antagonistic ability of bioagents was studied under in vitro conditions. The present study was undertaken to explore the inhibitory effect of commercial algal compounds, Weed-Max and Oligo-Mix, against some soil-borne pathogens. In growth...

Bacillus amyloliquefaciens SQR9 exhibited predominantly antagonistic activities against a broad range of soilborne pathogens. The fungi-induced SQR9 extracts possess stronger antifungal activities compared with SQR9 monoculture extracts. To investigate how SQR9 fine-tunes lipopeptides (LPs) and a siderophore bacillibactin production to control different fungal pathogens, LPs and bacillibactin p...

The antagonistic activity of two yeast strains (Pichia anomala (E.C. Hansen) Kurtzman, strain K and Candida oleophila Montrocher, strain O) against the parasitic complex responsible for banana crown rot was evaluated. The strains were applied at three different concentrations (10, 10, 10 cfu/ml) and their efficacy tested in vivo on three separate fungi (Colletotrichum musae (Berk. & Curt.) Arx,...

Prevalent fungal pathogens of cereals in Lithuania belong to diverse systematic groups and this makes search for microbial biocontrol measures rather difficult. One of the options would be broad-spectrum biocontrol agents. In order to find these, 1037 seed-borne and 11 soil-borne rhizosphere pathogenic fungi were isolated and their systematic position determined. Fungi of genera Alternaria, Ulo...

A common practice on Israeli dairy barns comprises daily cultivation of the manure. Cultivation is a mechanical process used to break up and till the manure bedding and it results in a drier and aerated bedding and cleaner cows, which consequently reduces the incidence of mastitis. Cultivation was associated with a shorter survival of Escherichia coli in cultivated manure as compared with noncu...

BACKGROUND AND OBJECTIVES To find antagonistic bacteria with potential antifungal activity against some pathogenic fungi, including Aspergillus niger, A. flavus, Fusarium moniliforme and Penicillium marneffei, a total of 148 agricultural soil samples from different sites of Tehran were examined. MATERIALS AND METHODS Antagonistic soils were selected by screening against A. niger on glucose-ye...
