Potassium dicarboxylatelukhulo lokuqala olungelulo amayeza okubulala iintsholongwane olukhuthaza isongezo sesondlo esivunywe yiManyano yaseYurophu.Ingumxube we-potassium dicarboxylate kunye ne-asidi ye-formic ngokusebenzisa i-intermolecular hydrogen bond.Isetyenziswa kakhulu kumantshontsho eehagu nasekukhuliseni iihagu zokugqiba.Iziphumo zovavanyo lokutyisa zibonise ukuba ukongeza i-potassium dicarboxylate ekutyeni kweehagu kunokonyusa kakhulu ubunzima beehagu kwaye kunciphise inani lokufa okubangelwa lusulelo lwebhaktiriya.Ukongeza i-potassium dicarboxylate kwisondlo senkomo nako kunokuphucula isivuno sobisi lweenkomo.

Kolu phononongo, iidosi ezahlukeneyopotassium dicarboxylatezongezwa kwisondlo seprotheyini ephantsi iPenaeus vannamei, ukuze kuphononongwe iarhente ekhuthaza ukukhula esebenzayo nengenabungozi kokusingqongileyo.

Impahla nenkqubo

1.1 isondlo sokulinga

Ifomyula yokutya yokulinga kunye neziphumo zohlalutyo lweekhemikhali ziboniswe kwiThebhile 1. Kukho amaqela amathathu okutya kuvavanyo, kunye nemixholo ye-potassium dicarboxylate yi-0%, 0.8% kunye ne-1.5% ngokulandelanayo.

1.2 i-shrimp yovavanyo

Ubunzima bokuqala bomzimba kaPenaeus vannamei ngu (57.0 ± 3.3) mg) C. Uvavanyo lwahlulahlulwe lwaba ngamaqela amathathu kunye neempendulo ezintathu kwiqela ngalinye.

1.3 iindawo zokutya

Ukukhuliswa kwe-Shrimp kwakuqhutyelwa kwiikheji zenetha kunye neenkcukacha ze-0.8 mx 0.8 mx 0.8 M. zonke iikheji zomnatha zazibekwe kwidama lesamente eliqukuqelayo (1.2 m ukuphakama, 16.0 m ububanzi).

1.4 ilinge lokutyisa lefomati ye-potassium

Amaqela amathathu okutya (i-0%, i-0.8% kunye ne-1.5% ye-potassium dicarboxylate) yabelwa ngokungaqhelekanga kwiqela ngalinye emva kokulinganisa iziqwenga ze-30 / ibhokisi.Imali yokutya yayiyi-15% yobunzima bomzimba bokuqala ukusuka kwi-1 ukuya kwi-10, i-25% ukusuka kwi-11 ukuya kwi-30 ye-30, kunye ne-35% ukusuka kwi-31 ukuya kwi-40 yovavanyo.Ubushushu bamanzi yi-22.0-26.44 ℃ kwaye ubutyuwa buyi-15. Emva kweentsuku ezingama-40, ubunzima bomzimba bulinganiswe kwaye bubalwa, kunye nobunzima.

2.2 iziphumo

Ngokovavanyo lokuxinana kwesitokhwe, eyona nto iphezulu yokuxinana kweempahla yayiyi-30 yeentlanzi / ibhokisi.Izinga lokusinda kweqela lolawulo lali (92.2 ± 1.6)%, kwaye izinga lokusinda kweqela le-0.8% le-potassium diformate laliyi-100%;Nangona kunjalo, izinga lokusinda likaPenaeus vannamei lehla laya kutsho ku- (86.7 ± 5.4)%, xa inqanaba lokongezelela liye lanyuka laya kutsho kwi-1.5%.I-coefficient yesondlo nayo ibonise indlela efanayo.

3 ingxoxo

Kolu vavanyo, ukongeza i-potassium diformate kunokuphucula ngokufanelekileyo inzuzo yemihla ngemihla kunye nezinga lokusinda likaPenaeus vannamei.Kwabekwa umbono ofanayo xa kugalelwa i-potassium dicarboxylate kwisondlo seehagu.Kuye kwaqinisekiswa ukuba ukongezwa kwe-0.8% ye-potassium diformate kwi-shrimp feed ye-Penaeus vannamei ibe nefuthe elingcono lokukhuthaza ukukhula.URoth et al.(1996) ucebise ukongezwa kokutya okugqwesileyo kokutya kweehagu, okwakuyi-1.8% kwisondlo sokuqalwa, i-1.2% kwisondlo sokulunyulwa kunye ne-0.6% ekukhuliseni nasekugqibeni iihagu.

Isizathu sokuba i-potassium dicarboxylate inokukhuthaza ukukhula kukuba i-dicarboxylate ye-potassium inokufikelela kwindawo yamathumbu e-alkaline ebuthathaka ngokondla isisu sesilwanyana ngendlela epheleleyo, kwaye ibole ngokuzenzekelayo ibe yi-asidi ye-formic kunye ne-formate, ibonisa umphumo onamandla we-bacteriostatic kunye ne-bactericidal, okwenza amathumbu ezilwanyana avele " sterile" imeko, oko kubonisa ukukhula kwesiphumo.
