椰子水的自然预发酵条件对细菌纤维素合成的促进性影响
Facilitating Effects of Natural Pre-fermentation of Coconut Water on Bacterial Cellulose Yield
摘要
Abstract
In the production of bacterial cellulose (BC),raw coconut water is usually pre-fermented and then used,which has an important effect on improving BC production.In this study,the necessity and the exactness of the pre-fermentation process to promote BC synthesis were explored in three aspects:coconut water origin,natural pre-fermentation environment and pre-fermentation time.BC fermentation was carried out with pre-fermented coconut water as the BC-fermentation medium and inoculated with Komagataeibacter nataicola Y19.The results showed that fermented coconut water from different habitats at home and abroad could promote BC synthesis significantly after different duration under different pre-fermentation conditions,and three conditions had a great influence on the increase of BC production.When the pre-fermentation was carried out for 1-3 d in the laboratory environment,the facilitating effect of fermented coconut water from each origin on BC production was obvious,of which the fermented coconut water from Vietnam showed the greatest BC production increase on the second day of pre-fermentation,10.8 times of the control (fresh coconut water).When pre-fermention in the coconut processing factory environment,its BC yield only after 1 d was up to 14.48 g/L,which was 25.0 times of the control.It indicated that pre-fermenting environment was the most important.This paper firstly clarified the necessity and certainty of coconut water pre-fermentation process to promote BC synthesis.It laid a foundation for revealing the essential changes of coconut water pre-fermentation procedure and its mechanism for the regulation of BC fermentation.关键词
