The fungal cell wall not only plays a critical role in maintaining cellular integrity, but also forms the interface between fungi and their environment. The composition of the cell wall can therefore influence the interactions of fungi with their physical and biological environments. Chitin, one of the main polysaccharide components of the wall, can be chemically modified by deacetylation. This...

Chitin is a polysaccharide composed from N-acetyl-D-glucosamine units. It is the second most abundant biopolymer on Earth and found mainly in invertebrates, insects, marine diatoms, algae, fungi, and yeasts. Recent investigations confirm the suitability of chitin and its derivatives in chemistry, biotechnology, medicine, veterinary, dentistry, agriculture, food processing, environmental protect...

The deep marine subsurface is a vast habitat for microbial life where cells may live on geologic timescales. Because DNA in sediments may be preserved on long timescales, ribosomal RNA (rRNA) is suggested to be a proxy for the active fraction of a microbial community in the subsurface. During an investigation of eukaryotic 18S rRNA by amplicon pyrosequencing, unique profiles of Fungi were found...

• Fungal and shrimp chitosan were wet spun to monofilament yarns. Using adipic acid as solvent generally resulted in fibers with higher tensile strength compared obtained using lactic acid. Chitosan monofilaments showed a similar or better biocompatibility commercial sutures. are good candidates for being used Purified fungal crustacean by acids solvent. The lowest viscosity at which fiber form...

Separation of Trametes versicolor laccase from a commercial preparation was carried out using Three-Phase-Partitioning (TPP) technique. The conditions were optimized and the most favorable ammonium sulphate concentration (70% w/v), crude to t-butanol ratio (1.0:2.0) and pH (4.5) resulted in 56.22% yield with 1.65-fold purity of laccase. For further improvement in purification, an improved versi...

The aim of this paper was to synthesize and characterize microbial chitosan thin films for potential piezoelectric application. Microbial derived from the Aspergillus oryzae fungus via extraction deacetylation. Chitosan film characterized its surface morphology, chemical properties, tensile strength, topography. For application as a material, characteristics were presented in terms electromecha...

background facultative marine fungi could potentially be arsenic tolerant and may be able to remove this highly poisonous metal from the environment. objectives the objective of this work was to explore the degree of tolerance and removal efficiency of two facultative marine fungi. materials and methods facultative marine fungi aspergillus flavus and rhizopus spp. were exposed to 25 mg/l and 50...

Chitosan is a partially deacetylated linear polysaccharide composed of ?-1,4-linked units d-glucosamine and N-acetyl glucosamine. As well as structural component fungal cell walls, chitosan potent antifungal agent. However, the mode action poorly understood. Here, we report that effective for control rice blast disease. application impairs growth fungus Magnaporthe oryzae has pronounced effect ...

Chitosan is a naturally occurring polymer derived from the deacetylation of chitin, which an abundant carbohydrate found mainly in shells various marine and terrestrial (micro)organisms. has been extensively used to construct nanoparticles (NPs), are biocompatible, biodegradable, non-toxic, easy prepare, can function as effective drug delivery systems. Moreover, chitosan NPs have employed gene ...
