According to the results of our investigation, distinct bacterial isolates capable of breaking down agar were found in various nonmarine environments. The deficiency of reducing sugar in the control media demonstrates that the agar in the experiment is broken down by the bacteria to produce various oligosaccharides because the viscosity of the medium containing the agar was found to have been extremely high before inoculation, reducing with incubation duration and attaining a maximum after 48 hours. These isolates were subsequently used in tests along with additional investigation since they could create reducing sugar. Interestingly, the deterioration of agar appears to be mainly caused by Gram-negative bacteria. In order to study the agarase properties, the relative quantity of the enzyme secreted by the bacteria that hydrolyze the agar was used. The detection of extracellular agarase surrounding the colonies and the absence of stained halos on iodine-treated agar plates show that the agarase diffusing from the bacteria impacted the characteristics of the gel. Inconclusion, these agarsase-producing bacteria can be exploited for industrial applications. Waste agar from the plant tissue culture business can be utilized for a range of applications and this degraded agar can be explored for reliable and ecologically safe alternatives.
根据我们的调查结果,在各种非海洋环境中发现了能够分解琼脂的不同细菌分离株。对照培养基中还原糖的缺乏表明,实验中的琼脂被细菌分解产生了各种低聚糖,因为在接种前含有琼脂的培养基的粘度非常高,随着孵育时间的延长而降低,并在 48 小时后达到最大值。由于这些分离株可以产生还原糖,因此随后对其进行了测试和进一步的研究。有趣的是,琼脂的劣化似乎主要是由革兰氏阴性菌引起的。为了研究琼脂酶的性质,使用了水解琼脂的细菌分泌的酶的相对量。在菌落周围检测到胞外琼脂酶和碘处理琼脂平板上没有染色晕环表明,从细菌中扩散出来的琼脂酶影响了凝胶的特性。总之,这些产琼脂酶的细菌可以用于工业应用。可以利用植物组织培养业务中的废琼脂进行多种应用,并且可以探索这种降解的琼脂作为可靠和生态安全的替代品。
