Hujayra fabrikalarikatta hajmdagi hujayra madaniyatida keng qo'llaniladigan sarf materiallari turidir. Hujayralar juda nozik organizmlardir. Hujayralarning in vitro madaniyati o'ziga xos muhitni talab qiladi, uning bepushtligi asosiy talab hisoblanadi.
In vivo, detoksifikatsiya tizimi va immun tizimi mikroorganizmlar yoki boshqa zararli moddalarning kirib kelishiga qarshi tura oladi, lekin in vitro madaniyat jarayonida hujayralar tananing immunitet tizimini himoya qila olmaydi va mikroorganizmlardan himoya qilish va zararli moddalarni zararsizlantirish qobiliyatini yo'qotadi. Hujayralarning in vitro o'sishi va ko'payishini ta'minlash uchun steril ish joyini, yaxshi shaxsiy gigienani, steril reagentlar va vositalarni va aseptik ishlov berishni ta'minlash kerak.
Hujayralar zavodi madaniyatida keng tarqalgan mikrobial ifloslanishlar mikoplazma, bakteriyalar va boshqalarni o'z ichiga oladi. zamburug'lar. Mikoplazmaning o'limga olib keladigan toksikligi yo'q, hujayralar bilan uzoq vaqt birga yashashi mumkin va hujayralarga potentsial ta'sir ko'rsatadi, lekin hajmi kichik va uni aniqlash qiyin. Uni liken qizil yoki Hoechst33342 bo'yash orqali aniqlash mumkin. Bakteriyalar tez ko'payadi, qisqa vaqt ichida ko'p miqdorda ko'payadi va hujayralarni o'ldirish uchun toksinlar ishlab chiqaradi. Yalang'och ko'z bilan ko'rish mumkin bo'lgan ko'plab zamburug'lar mavjud bo'lib, ular madaniy muhit yuzasida suzib yuradi va ipsimon, quvursimon yoki dendritik bo'lishi mumkin.
Agar hujayra zavodidagi hujayralarda bakterial ifloslanish sodir bo'lsa, manba. kontaminatsiyani aniq vaziyatga qarab tahlil qilish kerak, keyin esa ifloslanish holatiga qarab davolash kerak. Agar ifloslanish juda jiddiy bo'lsa, madaniyatni tashlab, uni qayta ishlash tavsiya etiladi.
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.
