Abstract

Abstract Heat resistant thermophilic spore-forming bacteria, such as Aeribacillus (A.) pallidus, may contaminate the surfaces in food facilities resulting food spoilage of the products. The aim of this work was to determine the heat and disinfectant resistance of an A. pallidus strain that was isolated from a canning factory environment. Compared to other heat-resistant spore-forming bacteria, it did not prove to be very resistant to heat with a D10-values of A. pallidus from 12.2 min to 2.4 min (at 102 °C and at 110 °C), with a calculated z-value of 11.6 °C. Not only spores but vegetative cells showed resistance against all investigated disinfectants.

一种芽孢腐败菌的耐热性和抗菌性研究
摘要耐热嗜热孢子形成细菌,如苍白球芽孢杆菌,可能污染食品设施的表面,导致食品变质。本研究的目的是测定从罐头工厂环境中分离得到的一株苍白芽孢杆菌的耐热性和抗消毒剂性。与其他耐热孢子形成细菌相比,a . pallidus的d10值在12.2 ~ 2.4 min(102°C和110°C)之间,计算出的z值为11.6°C,证明其耐热性不强。孢子和营养细胞对所有消毒剂均表现出抗性。
