The main goal was to evaluate if dried cyanobacterium (Arthrospira platensis) biomass added to unpasteurised apple juice could inhibit growth of fungi dominant in apples and which fraction of cyanobacterium biomass contributed to this phenomenon. A. platensis biomass, its protein and/or polysaccharide fraction were added to the sterilised apple juice inoculated with Aureobasidium pullulans LW14 and stored at 4 °C for 96 h. Samples were tested against number of fungi and selected physical–chemical parameters. In the last research stage, protein fraction was added to the unpasteurised apple juice inoculated with A. pullulans LW14 to test its potency against fungi, lactic acid bacteria and acetic acid bacteria. When A. platensis biomass was added to the sterilised apple juice (1.15% w/v), it effectively inhibited growth of A. pullulans LW14 and the metabolism of all analysed sugars (glucose, sucrose and fructose). Protein fraction added to the sterilised apple juice contributed significantly to mycostatic properties of A. platensis. When protein fraction was added to unpasteurised apple juice, the same conclusions were obtained, however, except for inhibiting growth of A. platensis LW14, it inhibited growth of some bacteria.

当添加到未经高温消毒的苹果汁中时，钝顶节旋藻的干燥生物质可抑制出芽短梗霉 LW14 和某些细菌的生长。


主要目标是评估添加到未经高温消毒的苹果汁中的干燥蓝藻（钝顶节旋藻）生物质是否可以抑制苹果中占主导地位的真菌的生长，以及蓝藻生物质的哪一部分导致了这种现象。将钝顶芽孢杆菌生物质、其蛋白质和/或多糖部分添加到接种出芽短梗霉LW14的灭菌苹果汁中，并在4°C下储存96小时。对样品进行了真菌数量和选定的物理化学参数的测试。在最后的研究阶段，将蛋白质组分添加到接种出芽短梗霉 LW14 的未经巴氏消毒的苹果汁中，以测试其对抗真菌、乳酸菌和醋酸菌的效力。当将钝顶曲霉生物质添加到灭菌的苹果汁中（1.15% w/v）时，它有效地抑制了出芽短梗霉LW14 的生长和所有分析糖（葡萄糖、蔗糖和果糖）的代谢。添加到灭菌苹果汁中的蛋白质部分对钝顶曲霉的抑菌特性有显着贡献。当将蛋白质级分添加到未经巴氏消毒的苹果汁中时，得到了相同的结论，然而，除了抑制钝顶曲霉LW14的生长外，它还抑制了一些细菌的生长。
