※Enrichment culture(집적배양)
미생물학자 Martinus Beijerinck에 의해 처음 시도된 방법으로 aerobic N2-fixing bacterium Azotobacter 를 사용하여 배양하였다.
selection for aerobic N₂-fixing bacteria usually results
in the isolation of Azotobacter or its relatives. By contrast,
enrichment with fixed forms of nitrogen such as NH₄+
rarely results in N₂-fixing

culture is usually sustained on gel media, in much the same manner as bacteria are grown. Sufficient media consist of agar and the usual mix of macronutrients and micronutrients for the given cell type. For plant cells, enrichment with nitrogen, phosphorus, and potassium is especially important. Water is provided as a constituent part of the gel media.

1. Manufacturing process of milk (Up & Midstream.)
Skim milk (milk) puts into dissolution tank and U.H.P(a high temperature sterilizer) then transfer into cultivation tank. It transfers to be homogeneous and remove the microorganism aga
culture but Norway has transformed its economy over the past decades into a modern industry. Now the oil and gas, maritime and the seafood sectors are the most remarkable industries in Norway. Above these, the energy & environment, healthcare and green IT are emerging industries. From now on look at these three important industries in Norway and then others in Norway more specifically.
