Potential fungicidal and antiaflatoxigenic effects of cinnamon essential oils on Aspergillus flavus inhabiting the stored wheat grains.

Wheat is one of the essential crops for the human and animal nutrition, however, contamination with aflatoxigenic fungi, due to the improper storage conditions and high humidity, was the main global threats. So, preventing the growth of aflatoxigenic fungi in stored wheat grains, by using different essential oils was the main objective of this work. Aspergillus flavus EFBL-MU12 PP087400, EFBL-MU23 PP087401 and EFBL-MU36 PP087403 isolates were the most potent aflatoxins producers inhabiting wheat grains.

Application of artificial neural networks for enhancing lipase synthesis for green biodiesel production.

Biodiesel is a sustainable, and renewable alternative to fossil fuels that can be produced from various biological sources with the aid of lipases. This study developed a simple and novel fungal system for lipase biosynthesis to be used for catalyzing the oily residuals into biodiesel, employing the artificial neural network (ANN), and semi-solid-state fermentation (SSSF). was selected among agro-industrial oily residuals as a substrate for lipase biosynthesis by MH47297.

Detection and Control of Biofilm Formation by from Febrile Neutropenic Patient.

Introduction: Febrile neutropenia (FN) is the evolution of fever in a patient with neutropenia over 38.0°C. Neutropenia is diagnosed when absolute neutrophil count (ANC) <1500 cells/µL.

Potential of fungal metabolites as a biocontrol agent against cotton aphid, Aphis gossypii Glover and the possible mechanisms of action.

The present study investigated the insecticidal activity of the different organic extracts from the entomopathogenic fungi, Cladosporium cladosporioides, Metarhizium anisopliae, Purpureocillium lilacinum, and Trichoderma longibrachiatum towards cotton aphid, Aphis gossypii. The methanol extracts from the mycelia and spores of C. cladosporioides and P.

Phytochemical, antimicrobial and antiquorum-sensing studies of L.: a revision on the structure of 1β,2α,3β,19α,23-pentahydroxy-urs-12-en-28-oic acid.

Phytochemical study of the aerial part of L. led to the isolation of nine compounds. The structure of 1β,2α,3β,19α,23-pentahydroxy-urs-12-en-28-oic acid () was revised and confirmation of the stereochemical configuration of the hydroxyl groups was established using NOESY and selective decoupling experiments.

Trichoderma harzianum: a biocontrol agent against Bipolaris oryzae.

Rice brown spot, caused by Bipolaris oryzae, can be a serious disease causing a considerable yield loss. Trichoderma harzianum is an effective biocontrol agent for a number of plant fungal diseases. Thus, this research was carried out to investigate the mechanisms of action by which T.
