Abstract

The Enteromorpha prolifera biochar and 4A zeolite-modified biochar based on different pyrolysis temperatures were prepared. The biochar of good biocompatibility with Bt was selected by studying the effects of different biochar on the survival rate and salt tolerance of Bacillus thuringiensis (Bt). The biochar microspheres loaded with Bt were prepared with sodium alginate, pectin, and chitosan. The effects of the addition of biochar on the particle size and ball formation rate of the microspheres were investigated. The structure of the microspheres was characterized by SEM and FTIR, and the SR of the microspheres under different pH conditions were evaluated. The results showed that 4A zeolite-modified biochar prepared at 500 ℃ (GH500) had good compatibility with Bt, and could improve the salt tolerance of Bt. The prepared microspheres have a uniform shape and particle size, and their swelling characteristics were pH-responsive, the microspheres containing biochar exhibited good swelling properties under alkaline conditions.

4A 沸石改性肠藻生物炭的制备及其在苏云金杆菌微球中的应用

制备了基于不同热解温度的 Enteromorpha prolifera 生物炭和 4A 沸石改性生物炭。通过研究不同生物炭对苏云金芽孢杆菌（Bt）存活率和耐盐性的影响，筛选出与 Bt 具有良好生物相容性的生物炭。用海藻酸钠、果胶和壳聚糖制备了负载 Bt 的生物炭微球。研究了生物炭的添加对微球粒径和成球率的影响。利用扫描电镜和傅立叶变换红外光谱对微球的结构进行了表征，并评估了微球在不同 pH 条件下的 SR。结果表明，在 500 ℃ 下制备的 4A 沸石改性生物炭（GH500）与 Bt 具有良好的相容性，可提高 Bt 的耐盐性。制备的微球具有均匀的形状和粒度，其溶胀特性对 pH 值有响应，含有生物炭的微球在碱性条件下具有良好的溶胀特性。
