Is foinse coitianta éilliúcháin é éilliú baictéarach nuair a úsáidtear cell factory truailliú: Tá truailliú baictéarach difriúil ó fhoinsí truaillithe eile. Nuair a bheidh na cealla sa mhonarcha cealla truaillithe, tá sé éasca a bhrath. I bhformhór na gcásanna, casann an tuaslagán cultúir buí i mbeagán ama, rud a léiríonn go dtáirgtear líon mór substaintí aigéadacha, agus go dtarlaíonn moirtiúlacht soiléir; Ní raibh an meán cultúir measctha ar dtús, ach tar éis beagán croitheadh, shnámh go leor substaintí turbid. Breathnaíodh faoi mhicreascóp inbhéartaithe, is féidir a fheiceáil go bhfuil líon mór cáithníní sféarúla ag snámh sa mheán cultúir, agus uaireanta tá líon mór baictéir ann ar agus timpeall an dromchla cille, agus stopann na cealla ag fás agus léiríonn siad nimhiú. Nuair is gá, is féidir méid beag smearaidh meán cultúir a ghlacadh le haghaidh staining chun an cineál baictéir a chinneadh; más rud é nach bhfuil roinnt athruithe meán cultúir soiléir agus go bhfuil amhras faoi éilliú, is féidir méid beag meán cultúir a chur leis an meán brat agus saothraithe ag 37 céim freisin chun a bhrath. chun cealla saothraithe, lena n-áirítear Escherichia coli, Staphylococcus albus, Pseudomonas, etc. Cad ba chóir a dhéanamh má tá na cealla éillithe ag baictéir?

Cóireáil truaillithe: Tar éis truailliú baictéarach a fháil, turraing is féidir teiripe a dhéanamh le 5-10 huaire an méid is gnách ar antaibheathaigh, agus is féidir an meán cultúir traidisiúnta a athrú tar éis 24-48 uair an chloig de chógas. Tá an modh seo éifeachtach maidir le truailliú luath. Má aimsítear go déanach é agus go bhfuil an t-éilliú tromchúiseach, moltar na cealla a chaitheamh amach. Is féidir antaibheathaigh a chur le meán cultúir an mhonarcha cille a chosc agus a dhíchur méid beag éilliú baictéarach. Má dhéantar cultúir ilchealla, ba cheart an gaireas a dheighilt go docht chun ionfhabhtú traschealla a chosc.

Treatment of pollution: After bacterial pollution is found, shock therapy can be performed with 5-10 times the usual amount of antibiotics, and the conventional culture medium can be changed after 24-48 hours of medication. This method is effective in early pollution. If it is found late and the contamination is serious, it is recommended to discard the cells.

The key to bacterial contamination is prevention. Adding antibiotics to the culture medium of the cell factory can prevent and eliminate a small amount of bacterial contamination. If multiple cell cultures are performed, the apparatus should be strictly separated to prevent cross-cell infection.

The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.

In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.

Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.

In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
