The fungus Aspergillus tubingensis (strain OY907) was isolated from the Mediterranean marine sponge Ircinia variabilis. Extracellular extracts produced by this strain were found to inhibit the growth of several fungi. Among the secreted extract components, a novel anhydride metabolite, tubingenoic anhydride A (1) as well as the known 2-carboxymethyl-3-hexylmaleic acid anhydride, asperic acid, a...

The filamentous fungus Cochliobolus carbonum produces endo-alpha 1,4-polygalacturonase (endoPG), exo-alpha 1,4-polygalacturonase (exoPG), and pectin methylesterase when grown in culture on pectin. Residual activity in a pgn1 mutant (lacking endoPG) was due to exoPG activity, and the responsible protein has now been purified. After chemical deglycosylation, the molecular mass of the purified pro...

Abstract Plants in various republics of the world face many dangers, including diseases that threaten crop productivity. The development and increase novel species infectious pathogens have made plant growth threatened. Fusarium wilt is one fiercest affecting vegetables, which causes a great loss quality quantity pepper plants all over world. In this study, stimulation physiological immune resp...

Emerging fungi resistant to triazoles are a concern because of the increased use of medical triazoles and exposure to agricultural triazoles. However, little is known about the levels of triazole susceptibility in outdoor airborne fungi making it difficult to assess the risks of inhalation exposure to airborne, antifungal-resistant fungi. This study examined triazole susceptibilities of the air...

Silver nanoparticles (AgNPs) have been broadly used as antibacterial and antiviral agents. Further, interests for green AgNP synthesis have increased in recent years and several results for AgNP biological synthesis have been reported using bacteria, fungi and plant extracts. The understanding of the role and nature of fungal proteins, their interaction with AgNPs and the subsequent stabilizati...

Aim: High free fatty acids (FFA) content of cocoa beans is high lead to alter quality butter fraction and chocolate manufactured. During primary post-harvest processing, harbor lipase producing mold speciess could trigger the accumulation FFA. This study investigated improvement raw material sourced from Côte d’Ivoire regarding its FFA concentration.
 Methods: Fermented dry were sampled on...

Aspergillus section Nigri includes some of the most important species for biotechnology and its species are of widespread occurrence. During our surveys of various food products and tropical soil we isolated several aspergilli belonging to section Nigri. In this paper, four new sclerotium and/or ochratoxin A producing species belonging to this section are proposed. In addition, based on a polyp...
