Abacwaningi eBinghamton University, State University of New York, basungule inqubo yokuguqula imfucuza yokudla ibe yipulasitiki ebolayo. Ngokusho kwencwadi ethi Bioresource Technology, lolu cwaningo lunikeza ukuqonda okuyisisekelo ezinkampanini ezifuna ukwandisa inqubo.
Ithimba eliholwa ngumfundi weziqu zobudokotela uTianzheng Liu kanye noSolwazi uSha Jin basebenzise imfucuza yokudla, eguqulwe yaba yi-lactic acid ngokubilisa, njengomthombo wekhabhoni webhaktheriya i- Cupriavidus necator . Leli bhaktheriya likhiqiza i-polyhydroxyalkanoate (PHA), ipulasitiki ebolayo engavunwa ngesilinganiso esingaba ngu-90% bese icutshungulwa ibe yiphakheji noma eminye imikhiqizo. I-Ammonium sulfate yasebenza njengomthombo we-nitrogen.
Ngokusho koMnyango Wezolimo wase-US, i-30 kuya ku-40% yokudla kwase-U.S. iphelela kudoti, ikhiqiza izigidigidi zamakhilogremu emfucuza kanye nokukhishwa kwegesi ebamba ukushisa. Le ndlela ingabhekana kokubili inkinga yokulahlwa kokudla kanye nokungcoliswa kwepulasitiki. Ucwaningo selukhombisile ukuthi imfucuza yokudla ingagcinwa isikhathi esingangesonto ngaphandle kokuphazamisa inqubo, nokuthi izinhlobo ezahlukene zemfucuza zingacutshungulwa ndawonye inqobo nje uma izinga lokushisa ne-pH kulawulwa.
"Le ncwadi igcizelela ukubaluleka kwesayensi kanye nokufaneleka kwemvelo," kusho uJin. Uhlela ukukhulisa inqubo futhi ufuna uxhaso noma ozakwethu bezimboni. Okuqinile okusele ekuvubeleni kuzothuthukiswa njengomanyolo ophilayo.
