Contents of crude protein （ CP）, total sugar and reducing sugar were taken as indicators. Effects of initial pH, ratio of yeast to fungi species, incubation time and liquid volume on production of single cell pro- tein （SCP） feed was studied, and technological conditions on production of SCP feed by water chestnut peel were optimized by orthogonal test. Results showed that the production of SCP feed by water chestnut peel was optimal when pH was 5.0, ratio of yeast to fungi species was 2： 1, fermentation time was 2 d and the liquid volume was 70 mL / 250 mL. Under the optimum conditions, content of fermentation CP was 64.25%, content of total sugar was 19.8%, content of reducing sugar was 5.0%, content of coarse fibre was 0.0% and content of ash was 8.04%.展开更多

The aim of this study was to valorize (OMWW) by anaerobic fermentation in the presence of cow manure in order to produce biogas and reduce their toxic load. Many tests were carried out by fermenting (OMWW) with polyphenols in the presence of cow manure in thermophile temperatures. The performance of this treatment was valuated through measurements of biogas production and by the determination of different parameters of fermented media (pH, volume of the biogas and polyphenols).展开更多
