Mahalo i nā honeycombs, ʻike mākou i ka mea huna e hiki ai i nā ilo ke wāwahi i ka plastic: ScienceAlert

Ua loaʻa i nā mea noiʻi ʻelua mau enzymes i loko o ka kohu o nā waxworms e wāwahi maoli i ka plastic maʻamau i loko o nā hola i ka wela lumi.
ʻO ka polyethylene kekahi o nā plastic i hoʻohana nui ʻia ma ka honua, i hoʻohana ʻia i nā mea āpau mai nā pahu meaʻai a i nā ʻeke kūʻai.ʻO ka mea pōʻino, ʻo kona paʻakikī hoʻi e lilo ia i mea haumia mau - pono e hana ʻia ka polymer i nā wela kiʻekiʻe e hoʻomaka i ke kaʻina hana hoʻohaʻahaʻa.
Loaʻa i ka wai o Waxworm ka enzyme wale nō i ʻike ʻia e hana ma luna o ka polyethylene i hana ʻole ʻia, e hana i kēia mau protein kūlohelohe i mea pono loa no ka hana hou ʻana.
Ua ʻike ʻole ʻo Federica Bertocchini i ka hiki o nā ilo wax ke hoʻohaʻahaʻa i ka plastic i kekahi mau makahiki i hala.
"I ka hopena o ke kau, waiho mau nā beekeepers i kekahi mau hives ʻole e hoʻi i ke kula i ka pūnāwai," i haʻi aku ai ʻo Bertocchini i ka AFP.
Hoʻomaʻemaʻe ʻo ia i ka hive a hoʻokomo i nā ilo wax i loko o nā ʻeke plastik.I kona hoʻi ʻana mai ma hope o kekahi manawa, ʻike ʻo ia ua "leaky" ka ʻeke.
ʻO ka Waxwings (Galleria mellonella) he mau ʻōnohu e lilo ana i mau muhu wax pōkole i ka wā lōʻihi.Ma ka pae larval, noho nā ilo i ka hive, e ʻai ana i ka beeswax a me ka pollen.
Ma hope o kēia ʻike hauʻoli, ua hoʻomaka ʻo Bertocchini a me kāna hui ma ka Center for Biological Research Margherita Salas ma Madrid i ka nānā ʻana i ka wai wormworm a hoʻopuka i kā lākou hopena ma Nature Communications.
Ua hoʻohana nā mea noiʻi i ʻelua ʻano: gel permeation chromatography, ka mea e hoʻokaʻawale i nā molekole e pili ana i ko lākou nui, a me ke kinoea chromatography-mass spectrometry, e hōʻike ana i nā ʻāpana mole e pili ana i kā lākou mass-to-charge ratio.
Ua hōʻoia lākou e wāwahi ka saliva i nā kaulahao hydrocarbon lōʻihi o ka polyethylene i loko o nā kaulahao liʻiliʻi liʻiliʻi.
A laila hoʻohana lākou i ka loiloi proteomic e ʻike i kahi "lima lima o nā enzymes" i loko o ka saliva, ʻelua o ia mau mea i hōʻike ʻia e oxidize polyethylene, kākau nā mea noiʻi.
Ua kapa nā mea noiʻi i nā enzymes "Demeter" a me "Ceres" ma hope o nā akua wahine Helene a me Roma o ka mahiʻai.
"I ko mākou ʻike, ʻo kēia polyvinylases nā enzymes mua hiki ke hana i nā hoʻololi i nā kiʻiʻoniʻoni polyethylene i ka lumi lumi i kahi manawa pōkole," kākau nā mea noiʻi.
Ua hoʻohui lākou ma muli o ka lanakila ʻana o nā enzyme ʻelua i ka "pae mua a paʻakikī loa i ke kaʻina hana hoʻohaʻahaʻa," hiki i ke kaʻina hana ke hōʻike i kahi "paradigm ʻokoʻa" no ka hoʻokele ʻōpala.
Ua haʻi ʻo Bertocchini i ka AFP ʻoiai ʻo ka hoʻokolokolo ʻana i ka wā mua, ua hui pū ʻia nā enzymes me ka wai a ninini ʻia ma luna o ka plastic i nā hale hana hou.Hiki ke hoʻohana ʻia ma nā wahi mamao me ka ʻole o nā ʻōpala ʻōpala a i ʻole i loko o nā hale pākahi.
Ke ulu nei ka microbes a me ka bacteria i ka moana a me ka lepo e hānai i ka plastic, e like me ka noiʻi 2021.
I ka makahiki 2016, ua hōʻike nā mea noiʻi ua loaʻa kahi hua bacteria i loko o kahi ʻāina hoʻopaʻa ʻāina ma Iapana e wāwahi ana i ka polyethylene terephthalate (ʻike ʻia ʻo PET a polyester).Ua hoʻoikaika kēia i nā ʻepekema ma hope mai e hana i kahi enzyme e hiki ke wāwahi koke i nā ʻōmole inu plastik.
Ma kahi o 400 miliona tons o ka ʻōpala palaka i hana ʻia i kēlā me kēia makahiki ma ka honua, ma kahi o 30% o ia mea he polyethylene.ʻO 10% wale nō o 7 biliona tons o ka ʻōpala i hana ʻia ma ka honua i hana hou ʻia i kēia manawa, e waiho ana i ka nui o nā ʻōpala i waiho ʻia ma ka honua.
ʻO ka hoʻohaʻahaʻa a me ka hoʻohana hou ʻana i nā mea e hōʻemi i ka hopena o ka ʻōpala plastik ma ke kaiapuni, akā hiki i ka loaʻa ʻana o kahi mea hana hoʻomaʻemaʻe clutter hiki ke kōkua iā mākou e hoʻoponopono i ka pilikia o ka ʻōpala plastik.
