Alicaligenes faecalis : identification and study of its antagonistic properties against Botrytis cinerea

  title={Alicaligenes faecalis : identification and study of its antagonistic properties against Botrytis cinerea},
  author={Dagoberto Rodriguez. Gonz{\~A}¡lez},
A Gram negative aerobic flagellated bacterium with fungal growth inhibitory properties was isolated from a culture of Trichoderma harzianum. According to its cultural characteristics and biochemical properties it was identified as a strain of Alcaligenes (aeca/is Castellani and Chalmers. Antisera prepared in Balbc mice injected with live and heat-killed bacterial cells gave strong reactions with the homologous immunogen and with ATCC 15554, the type strain of A. taeca/is, but not with… Expand

In vitro screening for the identification of potential biocontrol agents of Allium white rot
A multi-test in vitro system was designed to identify antagonistic micro-organisms of the Allium white rot pathogen, Sclerotium cepivorum, and identified inhibition of sclerotia formation and position of sclerosis formation in dual culture as the most discriminating variates in the screen. Expand
Antibiotic production and biocontrol activity by Bacillus subtilis CL27 and Bacillus pumilus CL45.
Antibiotic production was clearly indicated as the mode of action of in vivo biocontrol by strain CL27 against damping off caused by Bot. Expand
Inhibition of Botrytis cinerea spores by bacteria on the surface of chrysanthemum leaves
The results indicate that bacteria sedimenting on to leaves from the air could have an effect on the resistance of chrysanthemum to B. cinerea. Expand
Putative virulence factors of Botrytis cinerea acting as a wound pathogen
Grey mold fungus secretes a number of inducible attack enzymes which can degrade host cell walls to widen the infection, including β-glucosidase, pectin methylesterase, the polygalacturonases, and aspartate proteinase; laccase and benzyl alcohol oxidase appear to have roles of detoxifying compounds derived from the host during pathogenesis, a function that enhances the virulence of the pathogen.

Genetic studies of the phytopathogenic fungus Botryotinia fuckeliana (Botrytis cinerea) by analysis of ordered tetrads
Homothallism was not caused by inclusion of more than one nucleus in ascospores, and it occurred only in ascosores predicted to carry the MATl-2 allele after meiosis. Expand
The perfect stage of Botrytis convoluta.
No indisputable case for a genetic connection could be made from observations of this kind, and the evidence in support of a Botrytis-Sclerotinia connection was based on the association of the two forms on the same substrate, the close resemblance of the disease symptoms and the similarity of the mycelia and organs of attachment.

Alcaligenes defragrans sp. nov., description of four strains isolated on alkenoic monoterpenes ((+)-menthene, alpha-pinene, 2-carene, and alpha-phellandrene) and nitrate.
Four pseudomonad strains recently isolated on the monoterpenes (+)-menthene, alpha-pinene, 2-carene and alpha-phellandrene as sole carbon source and nitrate as electron acceptor are described as a new species belonging to the genus Alcaligenes, A. defragrans sp. Expand
Trichoderma: a review of biology and systematics of the genus
An overview of the interaction between humans and Trichoderma is presented, and a more intensive review of knowledge of systematics and taxonomy of the genus is presented. Expand
Significance of ecology in the development of biocontrol agents against soil‐borne plant pathogens
It is argued that antibiosis and some types of mycoparasitism have not been shown to be direct mechanisms of biocontrol in vivo; they might, instead, facilitate competition for substrates or sites as the primary mechanism of control. Expand
Iron Bound‐Siderophores, Cyanic Acid, and Antibiotics Involved in Suppression of Thielaviopsis basicola by a Pseudomonas fluorescens Strain
A Pseudomonas fluorescens strain (CHAo) involved in suppression of black root rot caused by Thielaviopsis basicola in the field, inhibited T. basicola when colonizing roots grown under sterileExpand
