- Abstract
Two biopolymers produced from submerged culture of edible mushrooms were directly observed by atomic force microscopy. Biopolymers were deposited on mica from dilute aqueous solution and imaged in air through a thin layer of adsorbed water and their hydrated structures were observed by a tapping mode. A single biopolymer molecule obtained from Cordyceps militaris was typical of a rod-like structure with bending point, which can form intra- and inter-molecular supercoils. In contrast, the image for low molecular weight biopolymer from Paecilomyces sinclarii is typical of a branched structure in which more extensive interaction leads to the formation of network-like matrix.
