Fabrication of oil (hexylsalicylate) encapsulated microcapsules comprising a shell gum Arabic and fungal chitosan via complex coacervation was investigated herein. This study highlights the influence fabrication conditions including ratio to chitosan, their net electrokinetic charge/zeta-potential turbidity on physico-mechanical properties resulting microcapsules. Glutaraldehyde employed as che...

Chitosan (C) is a natural antimicrobial compound that has been widely explored for wood protection, but its application limited by high leachability. Genipin biobased crosslinking agent can crosslink with chitosan under mild conditions. This study aims at examining the decay resistance and leachability of genipin-crosslinked (GC) treated against common wood-decaying fungi. GC formation was conf...

Terpenes from marine-derived fungi show a pronounced degree of structural diversity, and due to their interesting biological and pharmacological properties many of them have aroused interest from synthetic chemists and the pharmaceutical industry alike. The aim of this paper is to give an overview of the structural diversity of terpenes from marine-derived fungi, highlighting individual example...

In the search for new marine derived antibiotics, 43 epi- and endophytic fungal strains were isolated from the surface or the inner tissue of different marine plants and invertebrates. Through preliminary and secondary screening, 10 of them were found to be able to produce broad-spectrum antimicrobial metabolites. By morphological and molecular biological methods, three active strains were char...

Dendritic cells are known to be activated by a wide range of microbial products, leading to cytokine production and increased levels of membrane markers such as major histocompatibility complex class II molecules. Such activated dendritic cells possess the capacity to activate naïve T cells. In the present study we demonstrated that immature dendritic cells secrete both the YM1 lectin and lipoc...

Asexual spores of the filamentous fungus Rhizopus arrhizus were used as the resting biomass as they tolerate chitosan gelling for mycelia growing in chitosan beads. Biosorption of lead using the dead detergent pretreated chitosan-immobilised and grown fungal beads was performed with initial lead (II) nitrate concentrations ranging from 9.02 to 281.65 mg/L. The adsorption data were best correlat...
