摘要

许多食品和饮料生产厂家排出的废水都富含有机物,因此在排放前必须进行处理,以符合严格的环保法规,保护最终水质。具体来说,蜂蜜加工废水在处理前一直存放在储罐中,含有丰富的糖分,如果处理不当,这些高浓度的有机物会导致水质恶化,造成生态系统失衡。有不同的策略可以对废水进行适当处理,以实现可持续利用。其中一种技术是使用微生物(包括藻类、真菌、酵母菌或细菌),它比用于水质修复的化学程序更具成本效益,也更环保。由于酵母菌菌株生长迅速、健壮、代谢多样,因此经常被用于废水处理。在这项工作中,我们研究了从阿根廷一家出口公司产生的蜂蜜加工废水中分离出来的非酵母菌的生物修复潜力。将这些酵母菌株接种到蜂蜜废水中现有的菌群中,能更好地提高处理效果。这些结果表明,这些菌株在优化工业废水处理过程中的生物修复策略方面大有可为。

Isolation and assessment of highly sucrose-tolerant yeast strains for honey processing factory's effluent treatment.

Wastewater from many food and beverage manufacturers is enriched in organic content, and it must therefore be treated before being discharged to comply with the strict environmental regulations to protect the final water quality. Concretely, the honey processing wastewater, that remains in holding tanks until is disposal, is a rich source of sugars and this high level of organic material will degrade the water quality if not treated properly provoking an imbalance in the ecosystem. There are different strategies for an adequate treatment of this wastewater effluent to obtain a sustainable usage. One of the techniques that is more cost-effective and environmental friendlier than chemical procedures used for water remediation, is the use of microorganisms (including algae, fungi, yeasts, or bacteria). Given that they are fast-growing, robust, and metabolically diverse, yeast strains are often used for wastewater treatment. In this work, we have studied the potential for bioremediation of non Saccharomyces yeast isolated from a honey processing wastewater generated by an Argentine exporting company. The inoculation of these yeast strains to the existing flora in the honey wastewater yielded a better improvement in the treatment yield. These results suggest that these strains display a promising role could for optimizing bioremediation strategies in industrial wastewater treatment processes.

期刊介绍: AMB Express is a high quality journal that brings together research in the area of Applied and Industrial Microbiology with a particular interest in ''White Biotechnology'' and ''Red Biotechnology''. The emphasis is on processes employing microorganisms, eukaryotic cell cultures or enzymes for the biosynthesis, transformation and degradation of compounds. This includes fine and bulk chemicals, polymeric compounds and enzymes or other proteins. Downstream processes are also considered. Integrated processes combining biochemical and chemical processes are also published.
