Improving the Classification of Mycotoxin-producing Penicillia Associated with the Storage of Food
نویسنده
چکیده
Three hundred and forty eight strains of penicillia were examined by a team of specialists at IMI using morphological, physiological and biochemical criteria. Chief amongst these were the assessment of conidial ornamentation using scanning electron microscopy, growth on specific carbon and nitrogen sources, screening for enzyme production and thin layer chromatography of secondary metabolites. Variation in characteristics both within and between species was considered.

Natural Occurrence of Major Mycotoxins across the Ginger Value Chain in Nigeria
Background: Ginger which serves as both spices and medicine is susceptible to mycotoxin contamination. This research determined the incidence of major mycotoxins, including Aflatoxins (AFs), Ochratoxin A (OTA), and Fumonisins (FBs) in Nigerian ginger sampled from two main ginger producing states of Nigeria. Methods: Totally, 105 ginger samples were collected including freshly harvested and dri...
متن کاملSelection and evaluation of Debaryomyces hansenii isolates as potential bioprotective agents against toxigenic penicillia in dry-fermented sausages.
Biocontrol using autochthonous Debaryomyces hansenii isolates is a potentially suitable strategy for inhibiting toxigenic moulds in dry-cured meat products. The antifungal activity of 280 D. hansenii isolated from dry-cured meat products as well as the mode of action of the most active isolates against toxigenic penicillia were evaluated in this work. A 13.9% of the D. hansenii isolates showed ...

Aflatoxins are highly toxic compounds that are produced as secondary metabolites by some Aspergillus and Emericella species. Despite huge progress on aflatoxin research during the past 50 years, we have witnessed many cases of food contamination with aflatoxins all over the world. Aflatoxins have mutagenic and carcinogenic effects and they are capable of inducing hepatocellular carcinoma in hum...

Introduction: Aflatoxin M1 is an important mycotoxin frequently found in milk and dairy products. The main objective of this work was to study the stability of AFM1 during production and refrigerated storage of probiotic yogurt. Materials and methods: Two kinds of probiotic yogurt were made by cow’s milk artificially contaminated with aflatoxin M1 at a level of 100 ng/l, and fermented...

Fusarium verticillioides (F. verticillioides) is not only a primary pathogen of maize, but also can causedisease in other crops such as sorghum. Pathogenicity is related to mycotoxin production such as fumonisin.In the present study, 24 isolates of F. verticillioides, which were previously identified by phenotype basedmethods, were re-identified using restriction fragment length polymorphism (R...
