KOKOA
Ua ʻike ka poʻe ʻepekema ma ke Kulanui o Queensland, ma Australia, ʻo nā ilo o ka Zophobas morio beetles -i ʻike ʻia ʻo King worms a i ʻole zophobas-, hiki ke hoʻokomo i kahi meaʻai 'atypical' i kā lākou ʻai, akā pono loa i loko o ka honua piha i nā plastics. : polystyrene, he plastik maʻamau i loko o ka ʻeke a i ʻole nā ipu meaʻai. ʻO kāna 'ono' no kēia mea, i hoʻohui ʻia i kona nui nui, hiki ke kī i ka loaʻa ʻana o nā kumukūʻai kiʻekiʻe. Ua paʻi ʻia nā hopena ma ka puke pai 'Microbial Genomics'.
ʻAʻole ʻike hou nā ilo ʻai i ka plastik. Hiki i nā larvae o ka worm wax (Galleria mellonella) ke wāwahi i ka plastic i ka manawa hoʻopaʻa moʻolelo a loaʻa ka mahana o ka lumi ma muli o ko lākou kohu, e like me nā mea ʻike CSIC hou.
A i ʻole he ʻohana liʻiliʻi o ka ilo mōʻī, ʻo ka meaʻai, hiki nō ke ale i kēia mea. ʻO ka ʻokoʻa me nā zophobas ka nui o kona nui: ʻoiai ʻo ka meaʻai ʻai he 2.5 kenimika, ʻo nā ilo mōʻī, i hoʻohana ʻia no ka hānai ʻana i nā mea kolo a me nā manu i ka noho pio ʻana - a me ka meaʻai kanaka ma nā ʻāina e like me Thailand a me Mexico - hiki ke piʻi pālua, a hiki i ka 5 kenimika ka loa. ʻOiaʻiʻo, no kēia kumu ua kapa ʻia lākou he 'superworms'.
"Ua manaʻo mākou inā hiki i nā ilo liʻiliʻi ʻē aʻe ke ʻai i ka plastic, hiki paha i kēia mau ilo nui ke ʻai hou aku," wahi a Chris Rinke, nāna i alakaʻi i ka noiʻi. No ka hoʻāʻo ʻana i kēia kuhiakau, ua hānai ka hui i nā superworms i nā meaʻai like ʻole no ʻekolu pule. E mālama i kahi hui i hoʻolako ʻia; i kekahi Styrofoam 'ono'; aia ka mea ʻai hope loa, ma ke ʻano he pūʻulu hoʻomalu. Hiki i nā ilo i ʻai i ka plastic ke ola a loaʻa i ke kaumaha ke hoʻohālikelike ʻia me ka poʻe pōloli, "e manaʻo ana e hiki i nā ilo ke loaʻa ka ikehu mai ka ʻai ʻana iā Styrofoam," wahi a Rinke.
Ma hope o ka hoʻāʻo ʻana, ua ulu maʻamau nā superworms hānai ʻia e Styrofoam, lilo i pupae a laila luku loa i nā pipi makua; akā naʻe, ua hōʻike ʻia nā hoʻokolohua like ʻole i ka nalowale o ka ʻokoʻa microbial i loko o ko lākou ʻōpū a me nā pathogens. ʻO ia hoʻi, hiki i nā ilo ke ola i ka ʻai ʻana i ka plastic, akā ʻaʻole ia ka meaʻai momona loa no ko lākou olakino.
Lawe ʻana i nā ilo mai ka 'equation green'
Hōʻike ka poʻe noiʻi i ka 'hoʻonui' i kā lākou meaʻai, hiki ke hui pū ʻia ʻo Styrofoam me nā mea ʻai a i ʻole nā huahana mahiʻai. "He ala kēia e hoʻomaikaʻi ai i ke olakino o nā ilo a kōkua i ka nui o nā ʻōpala mai nā ʻāina Komohana," wahi a Rinke.
Akā, ʻoiai hiki ke hoʻohua hou i nā ilo no kēia kumu, ua noʻonoʻo ka mea noiʻi i kekahi manaʻo ʻē aʻe: ka hana ʻana i nā mea kanu hana hou e like me ka hana ʻana o nā larvae, ʻo ia hoʻi e ʻoki mua i ka plastic i ko lākou waha a laila e ʻeli iho ma o nā enzyme bacteria. "I ka hopena, makemake mākou e lawe i nā superworms mai ka hoʻohālikelike." ʻO ia ke kumu i kālailai ai ka hui i ke kaiāulu microbial gut i ka genetically e ʻike ai i nā enzyme i hoʻopaʻa ʻia i ka gene i komo i loko o ka palaka. ʻO ka manaʻo e hoʻomaʻemaʻe i kēia ʻimi i nā loiloi e hiki mai ana, e ʻike i nā enzyme maikaʻi loa e hoʻohaʻahaʻa i ka plastic a laila hoʻomaikaʻi hou iā lākou i loko o ka hale hana.
Hiki i nā huahana wāwahi o kēlā hopena ke hānai i nā microbes ʻē aʻe e hana i nā pūhui waiwai kiʻekiʻe, e like me nā bioplastics-i loaʻa mai nā mea ʻē aʻe ma waho o ka ʻaila a ʻoi aku ka maʻalahi. Aia paha i ka ilo ka hope.
