ABSTRACT Aflatoxin B1 (AFB1) is a highly carcinogenic substance primarily produced by Aspergillus flavus and parasiticus . Sterigmatocystin (ST), precursor of aflatoxin, mainly nidulans creber Both mycotoxins have similar biosynthetic pathways structural characteristics, yet ST considered to be less than AFB1. The scope this study investigate how environmental conditions such as pH, temperature, oxygen levels influence the production toxins good AFB1 producer Zt41 (isolated from corn in...
Probiotics are widely used in poultry farming and industry, as they offer numerous health performance benefits for birds. Probiotic Lactobacilli maintain gut microbiota balance, aid nutrient utilization, boost the immune system, increase stress resistance serve antibiotic alternatives. However, their impact on male reproductive function is not yet fully understood. This study investigated effect of a novel probiotic strain, Lactiplantibacillus plantarum SNI3 (LbSNI3), roosters. Twenty adult...
Authors studied the effect of sterigmatocystin from infected corn (STC), purified (PSTC), and aflatoxin B1 (AFB1) on lipid peroxidation glutathione redox parameters, including expression their encoding genes in a sub-chronic (14 days) trial. A total 144 three-week-old cockerels was divided into four experimental groups (n = 36 each). Control feed contaminated with STC or PSTC (1590 µg STC/kg 1570.5 feed), AFB1 (149.1 AFB1/kg feed). Six birds each group were sampled at day 1, 2, 3, 7 14...
A Gram-negative bacterial strain, named Kb82, was isolated from agricultural soil and a polyphasic approach used for characterisation to determine its taxonomic position. Based on 16S rRNA gene sequence analysis, the highest similarity found with Flavobacterium artemisiae SYP-B1015 (98.2%). The ANI (83.3%) dDDH (26.5%) values were ginsenosidimutans THG 01 fluviale HYN0086T, respectively. isolate is aerobic rod-shaped cells, positive catalase negative oxidase tests. DNA G+C content 34.7 mol%....
Due to global climate change, mould strains causing problems with their mycotoxin production in the tropical–subtropical zone have also appeared countries belonging temperate zone. Biodetoxification of crops and raw materials for food feed industries including aflatoxin B1 (AFB1) binding abilities lactobacilli is growing interest. Despite massive quantities papers dealing AFB1-binding lactobacilli, there are no data microbial structurally similar sterigmatocystin (ST). In addition, previous...
Aflatoxin B1 (AFB1) is a potent mycotoxin and natural carcinogen. The primary producers of AFB1 are Aspergillus flavus A. parasiticus. Sterigmatocystin (STC), another mycotoxin, shares its biosynthetic pathway with aflatoxins. While there abundant data on the biological effects AFB1, STC not well characterised. According to published data, more harmful systems than STC. It has been suggested that about one-tenth as mutagen measured by Ames test. In this research, S9 rat liver...
A novel Gram-stain-positive bacterial strain, designated as K13T, was isolated from compost and characterized using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, strain showed highest similarity (93.8 %) Paenibacillus nanensis MX2-3T. Cells K13T were aerobic, motile rods. The major fatty acids anteiso C15 : 0 (34.4 %), iso C16 (17.3 (10.0 %). menaquinone MK-7, polar lipid profile included diphosphatidylglycerol,...
Research on the ability of lactic acid bacteria (LAB) to bind aflatoxin B1 (AFB1) has mostly been focusing lactobacilli and bifidobacteria. In this study, AFB1 binding capacities 20 Enterococcus strains belonging E. casseliflavus, faecalis, faecium, hirae, lactis, mundtii, 24 Pediococcus species P. acidilactici, lolii, pentosaceus, stilesii, one strain Lactococcus formosensis L.garviae, 3 Weissella soli were investigated in MRS broth at 37 °C 0.2 µg/mL mycotoxin concentration. According our...
A Gram-stain-positive bacterium, designated TSL3T, was isolated from faeces of a porcupine, Hystrix indica, the Budapest Zoo and Botanical Garden, Hungary. On basis 16S rRNA gene sequence analysis, strain is phylogenetically related to family Micrococcaceae. The highest similarity found with Micrococcus terreus V3M1T (96.50 %) followed by Arthrobacter humicola KV-653T (96.43 %). Cells TSL3T were aerobic, non-motile coccoid-shaped. main fatty acids anteiso-C15 : 0 (54.4 %), iso-C16 (18.2 iso...
Abstract Mycotoxin production by aflatoxin B1 (AFB1) -producing Aspergillus flavus Zt41 and sterigmatocystin (ST) -hyperproducer creber 2663 mold strains on corn rice starch, both of high purity nearly identical amylose-amylopectin composition, as the only source carbon, was studied. Scanning electron microscopy revealed average starch particle sizes 4.54 ± 0.635 µm 10.9 2.78 µm, corresponding to surface area volume ratios 127 1/µm for 0.49 starch. Thus, a 2.5-fold difference in size...

Vegetables and fruits are staple food for the human mankind, they also considered as symbol of healthy nutrition. They consumed fresh cooked, in salad mixes, freshly pressed, fermented, minimally processed form, stored under different conditions, etc. Since close contact with environment, natural or artificial, have a microbiota on their surface highly variable function surrounding, prone to get contaminated pathogens, too. More attention is paid food-borne outbreaks last 10 years related...

Thermobifidas are thermophilic, aerobic, lignocellulose decomposing actinomycetes. The Thermobifida genus includes four species: T. fusca , alba cellulosilytica and halotolerans . YX is the far best characterized strain of this taxon several cellulases hemicellulases have been cloned from it for industrial purposes targeting paper industry, biofuel, feed applications.
