Silk fibers in the three layers of Attacus atlas (A. atlas) cocoons have morphological structure and tensile properties similar to that of Bombyx mori silk. Attempts are being made to produce silk for commercial applications from cocoons of relatively unknown wild insects due to the unique properties of the fibers and as a source of income and employment. In this research, A. atlas cocoons were used to study the chemical composition, morphology, physical structure and tensile properties of the… 

Mechanical Properties and Biocompatibility of Attacus atlas and Bombyx mori Silk Fibers Released from Cocoons by Alkali Treatment

TLDR
It is found that 100 mM NaOH concentration was efficient for complete A. atlas cocoon disintegration to individual fibers; while in case of B. mori, near complete hydrolysis was observed at the same concentration as shown SDS-PAGE and weight analysis.

Structure and Functions of Cocoons Constructed by Eri Silkworm

TLDR
The high sericin content of the cocoon coat, as well as the excellent ultraviolet absorption and antimicrobial abilities of Sericin, allows E cocoons to effectively prevent ultraviolet rays and microorganisms from invading pupae.

Study On Structure And Anti-Uv Properties Of Sericin Cocoons

Abstract Through biogenetic engineering, the posterior silk glands of Bombyx mori larvae are degenerated, and only the middle silk glands are retained to secrete sericin to produce sericin fibers, so

Tensile Properties and Biocompatibility of Indonesian Wild Silk Cricula Trifenestrata: A Preliminary Study

As it is reported in many publication about successful work of many research in developing biomaterial from Bombyx mori silk which is attract many researchers to observe the possibilities in using

Comparative Analysis of Structure and Properties of Stereoscopic Cocoon and Flat Cocoon

Abstract Cocoon is a kind of natural biopolymer material with reasonable structure and various functions. However, its structure and functions are often destroyed in practical application. In this

Non-mulberry Silk Fibers

Wild or non-mulberry silks are produced from various species of insects. Most popular non-mulberry silks that are commercially available are tasar (Antheraea mylitta), eri (Samia cynthia ricini), and

Cytotoxicity Test of Brown Silk from Attacus atlas L. on Rat Smooth Muscle Cells

Natural brown silk biomaterial from silkworm Attacus atlas L. (A. atlas L.) is a biopolymer that has many advantages compared to commercial silk from Bombyx mori (B. mori). The aim of this study was

Impact of different silkworm dietary supplements on its silk performance

This study aims to evaluate the effect of silkworm larva (Bombyx mori) diet supplementation with two amino acids (threonine and valine) on the cocoon production and on the structural and mechanical

Species identification of Bombyx mori and Antheraea pernyi silk via immunology and proteomics

TLDR
Compared with conventional methods for distinguishing silk species, immunological and proteomics techniques used in tandem can provide intact information and have the potential to provide accurate and reliable information for species identification.

Discerning Silk Produced by Bombyx mori from Those Produced by Wild Species Using an Enzyme-Linked Immunosorbent Assay Combined with Conventional Methods.

TLDR
The results of the noncompetitive indirect enzyme-linked immunosorbent assay (ELISA) indicated that the antibody that showed good sensitivity and high specificity can definitely discern Silk produced by Bombyx mori from silk produced by wild species, indicating the antibody-based immunoassay has the potential to be a powerful tool for tracing the beginnings of silk cultivation.
