• Substrate binding mechanism of P (3HB) depolymerase, KASOKA Ken-ichi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research on Priority Areas, Gunma University, Apr. 1999, Mar. 2003, Principal investigator, A P (3HB)-degrading bacterium Marinobacter sp. was isolated from deep sea. A P (3HB) depolymerase produced by the isolate was purified from the culture supernatant and characterized in detail. Further, a gene encoding the enzyme was cloned in E. coli. Genetic analysis revealed that the enzyme is composed of three functional domains, that is, catalytic, linker, and substrate-binding domains. Fungal P (3HB) depolymerase was purified from the supernatant of Penicillium funiculosom. A cDNA encoding the enzyme was cloned. Genetic analysis revealed that the enzyme lacks the substrate-binding domain (SBD) in contrast to bacterial enzymes. Due to the deletion, the fungal enzyme had less binding ability than those of bacterial enzymes. Homology search of the depolymerase genes showed that fungal enzyme gene may be incorporated from the degrading bacterial strain by the horizontal gene transfer. Mesophilic poly (ethylene succinate) (PESu)-degrading strains were isolated from natural environments, and identified. It was found that the degrading species belong to Gram-positive bacterium and fungus., Competitive research funding, 11217202

• Study of relationship between biodegradability and chemical structure of aliphatic polyester, Tachibana Yuya, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (C), Gunma University, 01 Apr. 2016, 31 Mar. 2020, Many researchers have considered that all aliphatic polyesters have environmental biodegradability. On the other hand, some researchers reported some of aliphatic polyesters did not degrade in natural environment. In this research project, we systematically synthesized aliphatic polyesters and carefully evaluated the biodegradability of them. We found that the biodegradability of linear aliphatic polyesters depended on the length of methylene chain and that of alicyclic polyesters depend on the linkage on the cyclic structure. Definitely, we revealed the relationship between biodegradability and chemical structure to design novel biodegradable polymer., 16K00607

• Contributing Factors for Optimal Remodeling of Tissue Engineered Vascular Graft, Naito Yuji, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (C), Yokohama City University, 01 Apr. 2015, 31 Mar. 2019, Tissue Engineered Vascular Graft (TEVG) emerged to solve inherent problem of biomaterial used for surgical repair of congenital heart disease. TEVG requires in vivo remodeling in which TEVG sometimes encounters unexpected tissue overgrowth. The study investigated contributing factors for optimal remodeling of TEVG. Initially, biodegradable scaffold material was used in this study, however, its availability was limited, new method was employed. Yokoyama U et al. described novel method in which arterial graft was fabricated by vascular cells periodically exposed to extremely high hydrostatic pressure (eHHP). This novel method was assembled to analyze extracellular matrix (ECM), therefore, we have employed this method for further analysis. TEVG fabricated by eHHP showed well organized ECM consistent with native vessels without unexpected tissue overgrowth. TEVG fabricated by eHHP has potential to remodel to mimic native vessels in vivo by controlled quality in vitro., 15K10228

• Attempt of performance upgrade of microbial fuel cells equipped with denitrifying bio-cathodes and applicability to nitrogen removal, WATANABE TOMOHIDE, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (C), Gunma University, 2011, 2013, Fundamental characteristics of microbial fuel cells (MFCs) equipped with denitrifying biocathodes under anoxic condition were experimentally investigated. The characteristics of cathodic reaction, microbial community in cathodic biofilm, the effects of operational condition and electrode configuration on MFC performance were discussed on the basis of the experimental results obtained. Biological nitrate reduction rate on cathode was rate-limiting step for power generation in the MFC equipped with denitrifying biocathodes. The power generation of MFC using a packed bed of granular graphite as electrodes reached 730mW/m3 with organic matter (acetate) degradation in anode compartment and denitrification in cathode compartment. In cathodic biofilm, autotrophic denitrifying bacteria such as Paracoccus denitrificans were predominantly detected., 23560639

• High performance modification of chemically synthesized biodegradable polyesters, MITOMO Hiroshi; KASUYA Ken-ichi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (C), Gunma University, 2001, 2002, Poly(L-lactic acid) is biodegradable polymer made from sustainable resources such as corn starch. But it begins to be softening above the gloss transition temperatue (50℃). Therefore, PLLA was mixed with triallyl isocyanurate (TAIC). After mixed with TAIC, PLLA was irradiated at various irradiation doses. Gel fraction and degree of swelling were measured and evaluated crosslinking formation. At 3% concentration of TAIC, 50 kGy of irradiation dose were the best condition for modification of PLLA. For this sample, gel fraction and degree of swelling were 85% and 6%, respctively. Thermo- mechanical analysis (TMA) of untreated PLLA showed softening above glass transition temperature(Tg) and significant elongation at around 90℃, while crosslinked sample treated under above conditions showed slight softening above Tg and melting point Tm, however it retains original shape even at above Tm. Thermal stability of PLLA was also obtained by annealing at around 90℃, however, the crosslinked sample showed not only the heat stability but also chemical proofing with good solvent for PLLA, such as chloroform. Moreover, the crosslinked PLLA showed properties of shape memory, even after once melted. Melt-quenced PLLA has very low crystallinity, which causes poor heat stability, so we tried annealing PLLA sample mixed with TAIC followed by irradiation. This method showed TMA behavior of partially crosslinked PLLA, i.e., partially softening at Tm but retained its shape above Tm. Biodegradability of the crosslinked PLLA was retarded slightly by introduction of crosslinking, however, usually it proceeds biodegradation after hydrolysis, there are no problem after the treatment in practice. Other chemically synthesized biodegradable polymers (e.g., bionolle)were treated with blending with inorganic particles or TAIC or TMAIC. Thermal stable and shape memory biodegradable polymers were obtained by these methods. These chemically synthesized biodegradable polymers were biodegraded with bacteria. 33 strain of bacteria were isolated, which were investigated by physiologicolly and morphologically, ond they are found to be gram negative and gram positive bacteria and fungi., 13650945
