“…Ironically, the ethanol used for these processes was oft en of petrochemical origin. 9 At that time, during the 1960s and 1970s, mineral oil prices were so low that petrochemical sources surpassed agricultural resources for the production of food and feed compounds with regard to economic competitiveness. Th erefore, this seemed an attractive way to increase food production.…”

“…Only 1% of the total crude oil production in those days (2 billion tons per year) was calculated to be suffi cient to produce approximately 15 million tons of yeast protein, which would cover the protein requirements of 1 billion people. 9 Aft er the 1970s, however, the price of petrochemical resources started to increase and the approach to converting these compounds into food and feed products was abandoned. Th e G. K. Skryabin Institute in Moscow studied the production of citric acid, isocitric acid and 2-oxoglutaric acid from ethanol using Yarrowia lipolytica strains.…”

The first pilot‐scale factories for the production of bioethanol from lignocellulose have been installed, indicating that we are on the brink of overcoming most hurdles for an economically feasible process. When bioethanol is competitive as biofuel with fuels originating from petrochemical resources, it will also become interesting to use lignocellulose as a feedstock for the fermentative synthesis of bulk chemicals. Lignocellulose hydrolysates, however, are highly complex and viscous media, posing challenges to oxygen transfer, product formation at low sugar concentration, product recovery, etc. Bioethanol is an exceptional product in this respect because it can be produced anaerobically, at low sugar concentrations, and can be easily removed from the broth by distillation. For products that do not have these benefits, another approach may be interesting, in which lignocellulose is first converted to bioethanol, which in turn serves as a substrate for a second conversion into the desired product, similar to the traditional production of acetic acid in vinegar. In this perspective, we compare these one‐stage and two‐stage conversions with respect to overall yield and productivity of the fermentation process and the differences that occur in product removal. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The optimum conditions employed were a substrate concentration of 6.0% (v/v), a temperature of 30~ pH 5.5 and (NH4)2SO4 as the nitrogen source. Although Nigeria produces hydrocarbon feedstocks, problems inherent in use of hydrocarbons for single cell protein production, such as cooling requirements and the possible retention of carcinogens in the residual biomass (Kharatyan, 1978), would make the system unprofitable in a developing country. Aniche (1985) has provided further evidence that local yeast isolates are being studied for possible use in production of baker's and brewer's yeast.…”

“…This is because the live yeasts deplete the B vitamins in the intestines of mammals causing avitaminosis [6]. Another obstacle is that the existence of a non-digestible cell envelope makes yeast protein (like other microbial protein) assimilation difficult [7]. KHILBERG [8] noted that about 8 and 25g per 100g protein are nucleic acids in microorganisms, yeasts inclusive.…”

The identification and enumeration of yeasts and the effect of chemical preservatives on the yeast load in Nigerian palm wine have been studied. Yeasts found largely belong to the genus Succhuromyces. Other genera found were Cundidu, Endomycopsis, Hunsenula, Kloeckeru, Pichiu, Sacchuromycoides and Schizosucchuromyces. The viable yeast count ranged from 0.5 x lo7 cfu/ml to 4.2 x lo9 in both fresh Elueis and Ruphiu spp. of palms. Yeasts in palm wine were least sensitive to sodium nitrate and most sensitive to sodium benzoate. The addition of these two chemical preservatives amongst others reduced the yeast count to 3.2 x 10" (in Raphiu sp.), and 4.1 x lo9 (in EIueis sp.) with 0.025% sodium nitrate and 1.2 x lo6 (in Raphiu sp.) and 1.9 x lo7 (in EIueis sp.) with 0.1 % sodium benzoate. The values of the yeast count in bottled and fresh palm wine were between 1.3 x lo3 cfu/ml to 9.8 x lo6 and 0.5 x lo7 to 4.2 x lo9, respectively. Maximum values of actual dry and theoretical yeast weights were 1.09 and 42 rng/ml, respectively.
