“…Perhaps the greatest obstacle to commercialization is that, compared to yeast, much less practical experience exists for the Z. mobilis fermentation. The extensive work done in the field of evaluation and optimization of fermentation techniques (recent publications: [82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99]) reflects the neccessity for the development of Z. mobilis-specific processes, especially those that can operate stably in a non-sterile environment. The narrow range of substrates utilized by Z. mobilis (i.e., glucose, fructose and sucrose), the formation of by-products in fructose and sucrose-containing media and the low salt tolerance are disadvantageous for commercial applications.…”

“…Cells were cultured in 2L baffled flasks at 37°C. 2. mobilis was grown in a semidefined medium ( Baratti et al, 1986 ), comprising ( as g/l ): yeast extract ( Oxoid ), 5, (NH4)2S04 1, KH2PO4 2, MgS04.7H20 0.5 and glucose 100; and a defined medium ( as g/l ): KHzPO4 3.48, N&Cl 2.41, MgS04.7H20 1 , FeS0+7HlO 0.01, calcium pantothenate 0.001, biotin 0.001, sodium citrate 0 .2 1 and glucose 100 ( Lawford and Stevnsborg, 1986 ). 2. mobilis was cultured anaerobically, controlled at pH 5.5 and 30°C in a 2L LH 500 series chemostat fermenter ( D = 0.07 h-l ).…”

“…Comparison of pantothenate synthesis operons in Z. mobilis isolates. Pantothenate auxotrophy is a common attribute among Z. mobilis isolates (Belaich and Senez 1965;De Ley and Swings 1976;Nipkow, Beyeler and Fiechter 1984;Galani, Drainas and Typas 1985;Lawford and Stevnsborg 1986;Cross and Clausen 1993). In fact, a survey of 38 Zymomonas sp.…”

“…However, these undefined supplements can also satisfy vitamin requirements (Lawford and Rousseau 1997). The vitamin pantothenate (vitamin B5), a precursor to coenzyme-A, is required by all Zymomonas isolates characterized to date (Belaich and Senez 1965;De Ley and Swings 1976;Nipkow, Beyeler and Fiechter 1984;Galani, Drainas and Typas 1985;Lawford and Stevnsborg 1986;Cross and Clausen 1993). Elimination of this auxotrophy, combined with utilizing N 2 as a nitrogen source, would circumvent the need for nutrient rich supplements altogether for Z. mobilis growth on cellulosic feedstocks.…”
