Figure 4From: Transformation of the matrix structure of shrimp shells during bacterial deproteination and demineralizationTEM based structural and elemental investigations of shrimp shells. Comparison of morphological details of P. monodon shrimp shells with element distribution by overlay of bright-field and energy-filtered TEM images in a) Exocuticle and b) Endocuticle before biological chitin treatment, c) Endocuticle between deproteination and demineralization and d) Endocuticle after deproteination and demineralization.Back to article page
