Ua hoʻokō kahi hui noiʻi mai ka Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences (TIB, CAS) i kahi holomua nui i ka biodegradation o nā plastics polyurethane (PU).
ʻenehana koʻikoʻi
Ua hoʻoholo ka hui i ke ʻano kristal o kahi PU depolymerase ʻano hihiu, e hōʻike ana i ke ʻano molekala ma hope o kona hoʻohaʻahaʻa pono ʻana. Ma muli o kēia, ua hoʻomohala lākou i kahi mutant pālua "artificial enzyme" hana kiʻekiʻe me ka hoʻohana ʻana i ka ʻenehana enzyme mining i alakaʻi ʻia e ka evolution. ʻO kona pono hoʻohaʻahaʻa no ka polyurethane ʻano polyester he aneane 11 mau manawa kiʻekiʻe ma mua o ka enzyme ʻano hihiu.
Nā Pōmaikaʻi a me ka Waiwai
Ke hoʻohālikelike ʻia me nā ʻano hana kino kuʻuna o ke kiʻekiʻe wela a me ke kaomi kiʻekiʻe a me nā ʻano kemika paʻakai kiʻekiʻe a me ka waikawa i hoʻopaʻa ʻia, haʻaheo ke ʻano biodegradation i ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka haumia haʻahaʻa. Hiki nō hoʻi iā ia ke hoʻohana hou ʻia o nā enzymes degradable i nā manawa he nui, e hāʻawi ana i kahi mea hana ʻoi aku ka maikaʻi no ka hana hou ʻana i nā plastics PU.
