異養細菌（Heterotrophic Bacteria） 指一類必須從外界攝取現成有機碳源（如糖類、蛋白質、脂肪等）作為能量和碳素來源的細菌。它們無法像自養生物那樣通過光合作用或化能合成作用自行制造有機物，而是通過分解其他生物體或有機物獲取營養。這類細菌在生态系統中扮演着至關重要的分解者角色，參與有機質的礦化過程，推動碳、氮等元素的生物地球化學循環。
營養依賴
異養細菌通過分泌胞外酶（如蛋白酶、澱粉酶）将大分子有機物分解為可吸收的小分子物質，再通過主動運輸攝入細胞内進行代謝。其能量來源包括呼吸作用（需氧或厭氧）或發酵過程。
生态多樣性
環境適應性
廣泛分布于土壤、水體、空氣及生物體内。部分種類可在極端環境（如深海、酸性溫泉）生存，其代謝多樣性支撐了生物圈的物質循環效率。
根據能量代謝方式可分為：
典型代表：大腸杆菌（Escherichia coli）是人類腸道中常見的兼性厭氧異養菌，既參與維生素合成，也可能導緻感染性疾病。
heterotrophic bacteria（異養細菌）是指不能通過光合作用或化能合成作用自主制造有機物，必須依賴外界現成有機物作為碳源和能量來源的細菌。以下是詳細解釋：
異養細菌無法利用無機碳（如CO₂）合成有機物，必須從環境中攝取有機碳化合物（如糖類、蛋白質等）來維持生命活動。其能量來源主要為有機物分解産生的化學能，與自養細菌（如光合細菌）形成鮮明對比。
根據獲取有機物的方式，異養細菌可分為兩類：
異養細菌的多樣性（heterotrophic bacteria diversity）是微生物生态研究的重要方向，涉及物種、功能及遺傳層面的差異。部分細菌為專性異養（obligative heterotrophic），即完全依賴有機物生存。
