Journal of Applied Microbiology, Accepted Article. Aims In the study, seven Plant Growth Promoting Rhizobacteria (PGPR) Azotobacter species were screened against three strains of Fusarium verticillioides to test its antifungal activity. Azotobacter strains were tested for the degradation of fumonisin produced by F.

Journal of Applied Microbiology, Accepted Article. Aims Mathematical models were employed to predict the growth kinetic parameters of F. graminearum and the accumulation of deoxynivalenol (DON) during wheat storage as a function of different moisture contents (MCs) and temperatures. Methods and results The colony counting method was used to quantify F.

Aims This work aimed to identify secondary metabolites from aerial parts of Euphorbia species functional for control of toxigenic Fusarium species responsible of cereal grain rots. Methods and Results Aerial parts of Euphorbia serpens, E. schickendantzii and E. collina were sequentially extracted with hexane, ethyl acetate and methanol. The extracts were tested against strains of F. verticillioides and F. graminearum by microdilution tests.The hexane extract of E.

Aims This study aimed to apply the volatile organic compounds from S. philanthi RL‐1‐178 (VOCs RL‐1‐178) as a fumigant to protect soybean seeds against the two aflatoxin‐producing fungi in stored soybean seeds. Methods and Results The antifungal bioassay tests on PDA dishes showed that 30 g L‐1 wheat seed inoculum of S. philanthi RL‐1‐178 exhibited total (100 %) inhibition on A. parasiticus TISTR 3276 and A. flavus PSRDC‐4.

Aim To evaluate biological control agents (BCA) against Fusarium graminearum on infected maize stalks as a means to reduce Fusarium head blight (FHB) in subsequently grown wheat. Methods and Results In the laboratory, BCAs were applied against F. graminearum on maize stalk pieces. Clonostachys rosea inhibited the perithecia development and ascospore discharge when applied before, simultaneously with and after the pathogen. In the field, we simulated a system with high disease pressure, i.e.

Aim To effectively make high‐quality silage in hot and humid area. Methods and Results The natural lactic acid bacteria (LAB) strains CZ149, XH358, XH753, and XH761 isolated from corn and Napier grass were screened by the potential of low pH growth and high lactic acid production, and their effect on silage quality, aerobic stability and aflatoxin B1 production of whole‐crop corn were also studied in Sichuan, China.

Aims To study the antimicrobial agents of the Bacillus velezensis strain HC6 and assess the application potential of Bacillus velezensis HC6 in maize. Methods and Results We applied a dual culture technique to test the antimicrobial activity of B. velezensis HC6 against bacteria and fungi of common contaminated crops. B. velezensis HC6 showed antagonistic action on pathogenic fungi, including Aspergillus and Fusarium, as well as pathogenic bacteria (especially Listeria monocytogenes).

Abstract

Aims

The purpose of this study was to evaluate the effect of warehouse storage conditions on the composition of the fungal community of green coffee beans (GCB) that were stored in jute sacks for one year.

Abstract

Aims

The aim of the present work is to report on the hydrolytic action of Alcaligenes faecalis isolated from soil samples and its ability to degrade ochratoxin A.

Abstract

Aims

Quantify aflatoxins, the potent carcinogens associated with stunting and immune suppression, in maize and groundnut across Zambia's three agroecologies and determine vulnerability to aflatoxin increases after purchase.

Abstract

Aims

This study was conducted to evaluate the biocontrol potential of Bacillus subtilis CICC 10034, Rhodobacter sphaeroides CGMCC 1.2182 and Agrobacterium tumefaciens CGMCC 1.2554 against patulin (PAT)-producer Penicillium expansum and their ability to remove PAT.

Abstract

Aims

isolate and characterize native yeast strains from broilers' environment as feedstuff, faeces and gut, and to evaluate their binding capacity for aflatoxin B1 (AFB1).

Abstract

Aims

This study was aimed to identify yeasts and moulds as well as to detect mycotoxin in corn silages in Southern Minas Gerais, Brazil.

Abstract

Aims

To assess frequencies of the Aspergillus flavus atoxigenic vegetative compatibility group (VCG) YV36, to which the biocontrol agent AF36 belongs, in maize-growing regions of Mexico.

Aims
The main objective of this study was to investigate the antifungal effect of Solanum torvum leaves against different field and storage fungi, and to identify its active compound. Also, to evaluate in vitro and in vivo inhibitory efficacy on toxigenic strains of Aspergillus flavus and Fusarium verticillioides.

Aims
To report fungal and aflatoxin contamination in stored tobacco leaves and potential of Foeniculum vulgare (fennel) seed essential oil (EO) as plant based preservative in protection of tobacco during storage.

Tetrodotoxin is a deadly neurotoxin which selectively inhibits Na+ activation mechanism of nerve impulse, without affecting the permeability of K+ ions. Because of this sodium channel blocking action, it is majorly being studied for biomedical applications. Tetrodotoxin is present in taxonomically diverse groups of animals inhabiting terrestrial, marine, fresh water and brackish water environments, still its origin remains unclear.

Aim
This study evaluated the binding capacity of aflatoxin B1 (AFB1) by two Enterococcus faecium strains (MF4 and GJ40) isolated from faeces from healthy dogs.

Materials and Methods
The binding assay was performed using 50 and 100 ppb of AFB1 analysing the effects of the viability, incubation time and pH on AFB1 binding. Binding stability was determined by washing three times the bacteria-AFB1 complexes with phosphate buffer saline.
