REDUCTION OF BIODEGRADABILITY OF UREA-CROSSLINKED STARCH AS SLOW RELEASE FERTILIZER UNDER SOIL CONDITIONS
Pengurangan kadar biodegradasi yang pesat bagi urea-silang kanji (UcS) filem adalah mungkin melalui penambahan alkali kraft lignin. Ujian awal perkuburan tanah telah mengesahkan ~ 80% (berasaskan kanji) adalah lebih biodegradasi bagi filem UcS di dalam tanah tidak steril berbanding tanah steril s...

Pengurangan kadar biodegradasi yang pesat bagi urea-silang kanji (UcS) filem
adalah mungkin melalui penambahan alkali kraft lignin. Ujian awal perkuburan tanah
telah mengesahkan ~ 80% (berasaskan kanji) adalah lebih biodegradasi bagi filem
UcS di dalam tanah tidak steril berbanding tanah steril sebagai keputusan ~ 98%
lebih tinggi bagi tanah mikrob biomas, ~ 94% lebih aktiviti daripada u- dan Bamilase
dan ~ 99% pelepasan saccharides lebih tinggi, 50% penambahan pelepasan
nitrogen. Ujian pengebumian filem komposit lignin dalam aerobik dan anaerobik
dalam tanah kecil telah dijalankan dan mengesahkan lignin boleh mengurangkan
kadar biodegradasi filem UcS ~ 1.34-10.71% (berasaskan kanji). Tindak balas kadar
maksimum Michaelis-Menten (Vmax) bagi tanah u-amilase, telah dikurangkan ~
1.23-2.03 kali dan B-amilase menurun sebanyak ~ 1.09-2.35, ini mungkin kerana
penjerapan enzim pada lignin. |
