“…Furthermore, because crustacean chitin and chitosan structure is inconsistent, fungal sources are a good alternative, especially for biomedical and pharmaceutical applications (Elsoud & El Kady, 2019). As a result, in recent years, biotechnological production of chitin and chitosan from fungal sources has gained extensive worldwide attention over conventional production of chitin and chitosan from Crustacea shell waste such as shrimp, crab, prawn, and crayfish (Razak, Pinjari, Begum, & Viswanath, 2018) and in the near future, it is expected that the use of fungi as a source of chitinous polymers will increase (Araújo et al, 2020).…”

“…[25,26] Chitosan (CS) is a natural and inexpensive polysaccharide produced from the deacetylation of chitin, which can derive from the numerous crustaceans like crabs, shrimps, lobster, fish scales, and some fungi. [27,28] CS is essentially composed of β-(1,4)-linked glucosamine units and contained abundant amino and hydroxyl groups, which can contribute to its chemical modification. [29,30] However, introducing effective and simple chemical transformations into chitosan chemistry may lead to noticeable progress of chitosan derivatives usage as support for metal-based catalysts.…”

The present work reports the design, synthesis, and characterization of palladium complex immobilized on chitosan/poly(o-phenylenediamine) (CS-PoPD-Pd) for the catalytic application in the Suzuki-Miyaura C C cross-coupling reaction through a nontoxic, inexpensive, eco-friendly, and practical method. Fourier-transform-infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), elemental mapping, X-ray diffraction (XRD), and inductively coupled plasma-optical emission spectrometry (ICP-OES) techniques were used for analyzing the prepared catalyst.Characterization studies showed that CS-PoPD-Pd was successfully synthesized according to our design. CS-PoPD-Pd composite demonstrated high product yield and high turnover number (TON) and turnover frequency (TOF) values with small catalyst loading for the Suzuki-Miyaura C C cross-coupling reaction under mild reaction conditions. Besides, the synthesized CS-PoPD-Pd composite could be readily recycled and reused for at least five runs without discernible loss of its catalytic activity.

“…The fungal species Mucor circinelloides of the Zygomycetes class has ignited much scientific interest due to the high chitin and chitosan content in its mycelia, which is around 35% of cell wall dry weight, comparable with the 20-30% chitin content found in crustacean shells [15]. Unlike crustacean chitin, which is a hard composite of highly mineralized chitin protein, the fungal cell wall is a polysaccharide-based three-dimensional network whereby chitin is linked with branched β-1,3and β-1,6-glucan via a β-1,4 linkage, and hence does not require harsh demineralization [16].…”

Dual Extraction of Crustacean and Fungal Chitosan from a Single Mucor circinelloides Fermentation

2020

Mucor circinelloides is a fungus that has been reported to produce ethanol, oil, protein, phosphate and glucosamine, depending on the available nutrients and cultivation conditions. Due to its ability to produce extracellular proteases, it is able to ferment polypeptides and amino acids broken down from various protein sources. In this study, we attempted to culture the Mucor circinelloides on waste substrates to deproteinize prawn shells for the extraction of chitin and subsequently extract chitosan from its fungal cell wall in a concurrent fermentation. The physio-chemical properties of the extracted crustacean chitin and fungal chitosan were determined by Fourier Transform Infrared Spectroscopy (FTIR) and Elemental Analysis (EA). We found that Mucor circinelloides grown on okara and coffee waste behaved as an excellent protease producer and successfully extracted chitin from prawn shells with a degree of deacetylation of 69.94% and 68.82%, respectively, comparable to commercial chitin (70.46%). The fungal chitosan extracted from the fermentation of Mucor circinelloides on red grape pomace substrate showed a degree of deacetylation of 61.05%, comparable to commercial chitosan (64.00%). Our results suggested feasibility of extracting chitosan from seafood waste-streams using cost-effective microbial fermentation.
