Recently, sericin has attracted increasing attention in biomedical and cosmetic research because of its useful properties including acceleration of wound healing, improvement of cell attachment, and inhibition of ultraviolet-B induced apoptosis. However, sericin films have poor mechanical properties, which restricts the application to those fields. In this study, cellulose nanofibril (CNF)/sericin composite films were fabricated by solvent casting, and the effects of ultrasonication time and CNF content on the solution turbidity, molecular conformation, and film mechanical properties of sericin film were examined. As the ultrasonication time increased, the turbidity of the CNF/sericin suspension decreased. Conversely, as the CNF content increased, the turbidity increased. However,
-sheet crystallization and mechanical properties remained almost unchanged by varying the ultrasonication time and CNF content, indicating that CNF is not effective to improve the mechanical properties of sericin films.

In an effort to obtain foundational data required to evaluate the therapeutic effect of educational insect rearing, this study surveyed current educational pet insect rearing practices in Korea and examined the expected psychological effects from participating in the activity. Data were collected from those who visited the special insect exhibition in May 2013 using a self-reporting survey. The results indicated that 48.3% of the responders had experienced insect rearing, and that rhino and stag beetles were the most commonly reared insects. Most of the respondents (83.1%) reported they were not currently rearing any insects, which suggested that insect rearing tends to be a one-time experience. Expected psychological effects could be divided into emotional (56.3%) and cognitive (41.8%) effects, and these varied by age and gender. The differences in expected psychological effects were particularly clear between adults and adolescents, the latter of whom were the main participants in the activity. It is therefore necessary to develop standardized manuals and care programs for more diverse insect species with which to help keep up consumer interest in educational insect rearing. These efforts will help champion the psychotherapeutic effects of educational pet insect rearing and enhance its role as a learning aid.

In a previous report, we identified several candidate antimicrobial peptides through de novo RNA sequencing of the centipede Scolopendra subspinipes mutilans. Here, we identify and characterize one of these peptides, Scolopendrasin I. We identified the centipede antimicrobial peptide Cecropin from the centipede transcriptome using an SVM algorithm, and subsequently analyzed the amino acid sequence for predicted secondary structure using a GOR algorithm. We identified an alpha helical region of Cecropin and named it Scolopendrasin I. We then assessed antimicrobial and hemolytic activity of Scolopendrasin I. Scolopendrasin I showed antimicrobial activity against various microbes, including antibiotic-resistant Gram-negative bacteria, in a radial diffusion assay. Scolopendrasin I had potent antibacterial activity against acne-associated microbes in a colony count assay and showed no hemolytic activity in a hemolysis assay. In addition, we confirmed that Scolopendrasin I bound to the surface of bacteria via a specific interaction with lipoteichoic acid and lipopolysaccharide, two components of bacterial cell membranes. In conclusion, the results presented here provide evidence that this is an efficient strategy for antimicrobial peptide candidate identification and that Scolopendrasin I has potential for successful antibiotic development.

Increased use of rhinoceros beetles (Allomyrina dichotoma ) for food and medicine, and their elevated value as pets has led to an increase in the number of their breeding farms. Mass breeding of the insects in these farms leads to entomological diseases. In this study, we investigate cannibalism resulting from overcrowded breeding of A. dichotoma larvae, as well as secondary fungal infections in epidermal wounds in the surviving larvae. Some of the fungi detected in the present study showed entomopathogenicity, and the larvae showed different times of death. In particular, larvae infected with Clonostachys sp., an endophytic plant fungus, grew for a long time after infection, but died without pupating.

The white-spotted chafer, Protaetia brevitarsis (Coleoptera: Scarabaeidae), has been traditionally used in Korea as a medicine for preventing liver-related diseases and suppressing liver cancer. Therefore, this insect is economically important and is commercially reared and sold in Korea. Recently, P. brevitarsis was listed as a temporal food ingredient by the Korean Ministry of Food and Drug Safety. Given the increasing economic importance of this beetle, we have sought to improve rearing conditions for its commercial production. In this study, we compared the effects of two food supplements, clay and charcoal, on the growth of second instar larvae of P. brevitarsis. Clay and charcoal are generally known as good adsorbent for removal of contaminating substances in insect feed. We fed second instar P. brevitarsis larvae a commercial diet consisting of fermented sawdust with seven different combinations of clay and/or activated charcoal, and measured their effects on weight gain for approximately 17 wk until larvae pupated. We found that addition of clay at 2.5% w/w of the fermented sawdust diet had no negative effect on weight gain of second instar P. brevitarsis larvae and thus may improve the quality of P. brevitarsis as a commercial food.

Enzymatic modification of proteins is often used to increase the biological activity of materials. Silkworm powder has been investigated as a functional food resource, but no study has been performed on its modification by commercial food enzyme. Therefore, this study aimed to determine the feasibility of such modification of silkworm powder by alkaline protease. The activity of the enzyme was confirmed using an azocasein assay. Subsequently the silkworm powder was hydrolyzed by enzymatic treatment. UV visible spectrometry showed that the supernatant of silkworm powder subjected to enzymatic treatment had a stronger absorption band than the untreated powder. SDS-PAGE electrophoresis showed that the molecular weight of silkworm powder decreased on enzymatic treatment. Thus the results indicate that commercial enzymes might be used to modify the characteristics of silkworm powder.
