BCRC Number: 81002
Organism: Afifella pfennigii
Synonymy: Rhodobium pfennigii Caumette et al. 2007
Author: Urdiain et al. 2009
History: << DSM << ATCC << R. Guyoneaud, Lab. d?Ecologie Mol?culaire-Microbiol., EA3525, Univ. Pau et Pays de l?Adour, France; AR2102
Other Collection No.: DSM 17143; ATCC BAA-1145
Source: benthic microbial mat in a brackish pond (R2) located on the rim of the Rangiroa atoll
Others: 1.特殊培養條件:需厭氧(可使用厭氧罐)、照光 (tungsten lamp)培養。
2.菌株復活:全部的冷凍菌液加到 10 mL 的培養基中, 於 28°C 厭氧照光培養14天後, 菌體呈現紅棕色至暗紅色,需再進行一次繼代培養,菌株的生長活性才會完全復活,之後即可進行放大培養或冷凍保存。
3.菌株繼代培養:接種菌液的體積必須佔新鮮培養基的 20% 至 50% (可視接種菌液的濃度決定添加之比例)。
4.菌株保存:繼代培養不要超過 3 次以上的菌液,離心濃縮後,以少量的新鮮培養基懸浮菌體沉澱後,菌液和冷凍保護劑 (如:20% 甘油) 以 1:1 比例混合均勻,即可進行冷凍保存 (PS.冷凍管只能解凍一次並且完全活化,不可重複冷凍解凍)。
Growth Conditions: 28°C 21 day(s)
