Molecular and chemical evaluation of patulin production of and like species isolated from Hungarian apples.

Mycotoxins are secondary fungal metabolites harmful to humans and animals. Patulin (PAT) is a toxin found in different food products but especially in apples and their derivative products. The most common fungi producers of this compound are and The production of patulin, as other mycotoxins, can be impacted by diverse phenomena such as water and nutrient availability, UV exposure, and the presence of antagonistic organisms.

Glass bead system to study mycotoxin production of Aspergillus spp. on corn and rice starches.

Mycotoxin production by aflatoxin B1 (AFB1) -producing Aspergillus flavus Zt41 and sterigmatocystin (ST) -hyperproducer Aspergillus creber 2663 mold strains on corn and rice starch, both of high purity and nearly identical amylose-amylopectin composition, as the only source of carbon, was studied. Scanning electron microscopy revealed average starch particle sizes of 4.54 ± 0.

Flavobacterium hungaricum sp. nov. a novel soil inhabitant, cellulolytic bacterium isolated from plough field.

A Gram-negative bacterial strain, named Kb82, was isolated from agricultural soil and a polyphasic approach was used for characterisation and to determine its taxonomic position. Based on 16S rRNA gene sequence analysis, the highest similarity was found with Flavobacterium artemisiae SYP-B1015 (98.2%).

sp. nov. a novel species on the borderline of the genus .

A Gram-reaction-negative bacterial strain, designated Kb22, was isolated from agricultural soil and characterized using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, the strain shows highest similarity (94.39 %) to M-SX103.

Sphingobacterium pedocola sp. nov. a novel halotolerant bacterium isolated from agricultural soil.

A Gram-reaction-negative halotolerant bacterial strain, designated Ka21, was isolated from agricultural soil and characterised using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, highest similarity was found with Sphingobacterium alkalisoli Y3L14 (96.72%).

Aflatoxin B1 and Sterigmatocystin Binding Potential of Non- LAB Strains.

Research on the ability of lactic acid bacteria (LAB) to bind aflatoxin B1 (AFB1) has mostly been focusing on lactobacilli and bifidobacteria. In this study, the AFB1 binding capacities of 20 strains belonging to , , , , , and , 24 strains belonging to species , , , and , one strain of and , and 3 strains of were investigated in MRS broth at 37 °C at 0.2 µg/mL mycotoxin concentration.

Aflatoxin B1 and Sterigmatocystin Binding Potential of Lactobacilli.

Due to global climate change, mould strains causing problems with their mycotoxin production in the tropical-subtropical climate zone have also appeared in countries belonging to the temperate zone. Biodetoxification of crops and raw materials for food and feed industries including the aflatoxin B1 (AFB1) binding abilities of lactobacilli is of growing interest. Despite the massive quantities of papers dealing with AFB1-binding of lactobacilli, there are no data for microbial binding of the structurally similar mycotoxin sterigmatocystin (ST).

Micrococcoides hystricis gen. nov., sp. nov., a novel member of the family Micrococcaceae, phylum Actinobacteria.

A Gram-stain-positive bacterium, designated TSL3T, was isolated from faeces of a porcupine, Hystrix indica, from the Budapest Zoo and Botanical Garden, Hungary. On the basis of 16S rRNA gene sequence analysis, the strain is phylogenetically related to the family Micrococcaceae. The highest 16S rRNA gene sequence similarity was found with Micrococcus terreus V3M1T (96.
