Description

Иовестно, что некоторые виды термофильных бактерий сбраживают растительные материалы и отходы , содержащие неодревесневшую или малоодревесневшую целлюлозу , а также сопутствующие ей другие углеводы - крахмал, гемицеллюлозу , сахара - на этиловый спирт и летучие органические кисЛОТБ1 . Хот-  образование при термофильном брожении цел; юлозы спирта и органических кислот и было известно, однако не было установлено , при каких услови х процесс идёт в сторону наибольшего образовани  спирта и при каких услови х образуетс  больше кислот.It is fair that some types of thermophilic bacteria ferment plant materials and waste containing non-woody or weakly woody cellulose, as well as other carbohydrates accompanying it — starch, hemicellulose, and sugar — into ethyl alcohol and volatile organic acids TL1. Hot formation during thermophilic fermentation is intact; It was known, however, it was not established under what conditions the process proceeds towards the greatest formation of alcohol and under what conditions more acids are formed.

Насто щее изобретение даёт возможность регулировать процесс сбраживани  целлюлозосодержащих материалов так, чтобы по желанию получить максимальный выход или спирта или органических кислот.The present invention makes it possible to regulate the process of fermentation of cellulose-containing materials so as to obtain, if desired, the maximum yield of either alcohol or organic acids.

Одним из основных условий дл  получени  при термофильном брожении целлюлозных материалов повышенных выхо/ ов этилового спирта  вл етс  наличие активных элективных культур, способных к образованию значительных количеств спирта при брожении.One of the basic conditions for obtaining, during thermophilic fermentation of cellulosic materials, increased yields of ethyl alcohol is the presence of active elective cultures capable of forming significant amounts of alcohol during fermentation.

, Выход спирта при брожении зависит от употребл ел ой дл  брожени  электи1и1ой культуры, так какThe alcohol yield during fermentation depends on the type used for fermentation of the electrolyte culture, since

раз.чичные культуры дают прн одних и тех же материалах различные выходы продуктов и, в особенности , спирта.For different cultures, with the same materials, different yields of products and, in particular, of alcohol are given.

При применении одной и той же элективной культуры выход спирта зависит от состо ни  культуры (её физиологической активности) и от условий, в которых ведётс  сбраживание .When using the same elective culture, the alcohol yield depends on the state of the culture (its physiological activity) and on the conditions under which the fermentation takes place.

Необходимые услови  дл  образовани  повышенных количеств спирта при брожении в основном свод тс  к следующему.The necessary conditions for the formation of elevated amounts of alcohol during fermentation generally boil down to the following.

Активна  реакци  среды должна находитьс  в пределах слабощелочной зоны рН 7,2-7,8, так как .сдвиг реакции среды в кислую сторону прежде всего сильно отражаетс  на выходе спирта, тормоз  его образование. Температура 55  вл етс  оптимальной дл  образовани  спирта. Повыщение температуры до 60 ведёт к ускорению брожени  при одновременном уве .пичении выхода летучих органических кислот. Установлено, что при прочих равных услови х - употреб .ление одной и той же среды одной и той же элективной культуры,соблюдение одинаковых, температурных условий, условий нейтрализации и пр., - количество посевного материала при термофильном брожени1 оказывает также вли ние наThe active reaction of the medium must be within the weakly alkaline zone of pH 7.2-7.8, since the shift of the medium to the acidic side is primarily reflected strongly at the alcohol output, and its formation is hindered. Temperature 55 is optimal for the formation of alcohol. Increasing the temperature to 60 leads to an acceleration of fermentation while increasing the yield of volatile organic acids. It has been established that, all other things being equal - the use of the same medium of the same elective culture, the observance of the same temperature conditions, neutralization conditions, etc., - the amount of seed during thermophilic fermentation also has an effect on
