Evaluation of ozonated and ultrasonically treated corn starch as an adsorbent for patulin in buffer solutions.

This study evaluates the potential of ozonated corn starch (OCS) and ultrasonicated ozonated corn starch (USOCS) as adsorbents for patulin removal in buffer solutions. The results indicated that dual modification significantly altered the starch's structure, introducing functional groups such as carbonyl and carboxyl groups, and increasing its surface area. These modifications led to enhanced patulin adsorption capacity.

Evaluation of effectiveness aqueous extract for some leaves of wild edible plants in Egypt as anti-fungal and anti-toxigenic.

Plants are one of a prefect source of natural effective compounds that have antimicrobial, and other activities. This study investigated the activity of the aqueous extract for three wild edible plants (, and ) at three concentrations (1.5, 2.

Impact of Silver Nanoparticles on Gene Expression in Producer Aflatoxin B1.

Aim: In this study, we evaluated the effect of silver nanoparticles (AgNPs) on the production of aflatoxin B (AFB) through assessment the transcription activity of aflatoxin biosynthesis pathway genes in ATCC28542.

Material And Methods: The mRNAs were quantitative by Real Time-polymerase chain reaction (qRT-PCR) of grown in yeast extract sucrose (YES) medium containing AgNPs. Specific primers that are involved in the AFB biosynthesis which highly specific to , O-methyltransferase gene (), were designed and used to detect the fungus activity by quantitative PCR assay.

Modified Rice Straw as Adsorbent Material to Remove Aflatoxin B1 from Aqueous Media and as a Fiber Source in Fino Bread.

The aims of the current work are in large part the benefit of rice straw to be used as adsorbent material and natural source of fiber in Fino bread. The rice straw was subjected to high temperature for modification process and the chemical composition was carried out and the native rice straw contained about 41.15% cellulose, 20.
