    Evaluation of conditions for fermentation of fish offal [Text] / T.Mikael Lassen // Agr. Sci. Finl. - 1995. - Vol. 4, N 1. - P11-17 . - ISSN 0789-600X
Перевод заглавия: Оценка условий ферментации рыбных отходов
Аннотация: Conditions for the lactic acid fermentation of fish offal were evaluated regarding the effect of substrate concentration (2.5 and 10% dextrose), preacidification with lactic acid (initial pH of 6.8, to 6.5 or 6.0), and inoculum size of Lactobacillus plantarum (10{7}, 10{8} and 10{9} colony forming units (cfu)/g). pH and lactic acid production were monitored during a two-weed storage period. A small-scale silo for fermenting fish offal was also constructed, and measurement of redox potential was evaluated as a means to estimate bacterial growth conditions. The most favourable conditions for fermentation, manifested by a low and stable pH and high lactic acid production, were achieved with an inoculum size of 10{8} cfu/g and 5% dextrose. Preacidification did not affect final pH. Redox potential was shown to give a reliable estimate of growth conditions for bacteria under anaerobic conditions by repidly falling to below-550mV in silage with a high lactic acid concentration.
