This study aims to investigate the effect of three factors, namely alumina trihydrate (ATH), montmorillonite (MMT) and irradiation dosage on the mechanical properties (tensile strength and elongation at break) of flame-retarded LDPE-EVA composites. In this study, full factorial design analysis was used to examine the effects of factors and their combination interactions on mechanical properties. ATH is the most significant factor in affecting the tensile strength of LDPE-EVA blends due to the poor compatibility effect between ATH particles and LDPE-EVA matrix. However, MMT is the least significant factor on tensile strength of LDPE-EVA composites. ATH was the most significant in affecting the elongation at break of LDPE-EVA blends. This is because the increasing of ATH amount in LDPE-EVA matrix could restrict the mobolity of polymer chains in LDPE-EVA matrix. However, the factor of irradiation dosage was found to be insignificant in affecting the elongation at break of LDPE-EVA blends.

Chitin production by Cunninghamella elegans (IFM 46109) was studied with a two-level full factorial design, varying time of cultivation and the concentration of D-glucose, L-asparagine, and thiamine in the culture medium. The material extracted was characterized by infrared and NMR spectroscopy. The highest chitin yield, 28.8%, was comparable with the highest in the literature and was obtained with a medium containing 60 g·L-1 of glucose, 3 g·L-1 of asparagine, and 0.008 mg·L-1 of thiamine. Increasing the time of cultivation from 24 h to 72 h did not affect chitin production. The three factors showed significant positive effects on chitin production, without interactions between them.Key words: chitin, chitosan, zygomycetes, Cunninghamella elegans.
