“…This suggests that these substrates are similarly improved by the addition of peptones or YE. These observations add to those of date juice where YE and peptone supplementation markedly improved growth of L. rhamnosus (Nancib et al, 2004). The three peptones alone gave good biomass results in the AS assays (Table 1).…”

“…The stimulant effect of YE on bacterial growth was often reported (Baralle and Borzani, 1988;Amrane and Prigent, 1993;Champagne et al, 1999;Nancib et al, 2005;Djeghri-Hocine et al, 2007b). However, Boudjema et al (2009) and Ghaly et al (2003) reported that at high concentrations of YE, the cell concentration decreases, under the effect of a high toxicity of YE.…”

In this study, the potential use of sweet whey as a base medium for lactic acid bacteria culture and its effect on the technological characteristics of lactobacilli was evaluated. Bacteria were grown on raw or deproteinized whey supplemented with different amounts of yeast extract and/or tomato juice. Results obtained showed that biomass production on whey supplemented with yeast extract was higher than those observed with tomato juice. Whilst, supplementation by either whey, tomato juice or yeast extract increased significantly the growth of both lactic acid bacteria, the performance was in the same range as that on a modified MRS medium. Additionally, acidification and proteolytic activities resulting from control and modified MRS medium were of comparable values. The present investigation demonstrates that sweet whey can be used as an alternative substrate for lactic acid bacteria cultural purposes and provide opportunity to make a new growth medium with low cost.

“…Although, molasses alone contains some amount of vitamin B6 17 , there is no available report suggesting the presence of other B vitamins in it. Nancib et al 18 reported an increase in lactic acid production from date juice by the use of yeast extract in the medium. Stehlik -Tomas et al 14 til 19 have reported an increase in rate of fermentation by the use of 0.2% chitin, xylan and acacia gum and a reduction in fermentation time by about 42 h as compared to molasses without the above supplements.…”

Cauliflower waste incorporation into cane molasses improves ethanol production using Saccharomyces cerevisiae MTCC 178

Diluted cane molasses having total sugar and reducing sugar content of 9.60 and 3.80% (w/v) respectively was subjected to ethanol production by Saccharomyces cerevisiae MTCC 178. Incorporation of dried Caulifl ower Waste (CW) in molasses at the level of 15 % increased ethanol production by nearly 36 % compared to molasses alone. Addition of 0.2 % yeast extract improved ethanol production by nearly 49 % as compared to molasses alone. When the medium containing diluted molasses and 0.2 % yeast extract was supplemented with 15 % CW, 29 % more ethanol was produced compared to molasses with 0.2 % yeast extract. Cell biomass, ethanol production, fi nal ethanol concentration and fermentation effi ciency of 2.65 mg mL -1 , 41.2 gL -1 , 0.358 gg -1 and 70.11 % respectively were found to be best at 15% CW supplementation level besides reduction in fermentation time but further increase in CW level resulted in decline on account of all the above parameters. This is probably the fi rst report to our knowledge, in which CW was used in enhancing ethanol production signifi cantly using a small quantity of yeast extract.
