Difference Between Bacterial Endospores and Fungal Spores

Thekey differencebetween bacterial endospores and fungal spores is the cellular organization of the two types of spores.细菌内孢子是核细菌中存在的休眠结构。Fungal spores are reproductive structures present in eukaryotic fungi.

Bacterial endospores are present within thebacterial cells, and they are dormant structures that can survive the harsh environment conditions. Consequently, these endospores germinate when the suitable environment conditions get fulfilled. In contrast, fungal spores are exospores that release to the exterior for sporulation.

What are Bacterial Endospores?

Bacterial endospores are prokaryotic in nature and present in spore-forming bacteria such as芽孢杆菌，梭菌，等等。这些是细菌中的休眠结构，可在极端恶劣的环境条件下（例如温度波动，辐射和毒性条件）生存下来。孢子形成的整个过程发生在不同的阶段。

孢子形成

这是孢子形成的过程。覆盖内孢子的DNA片段之间形成双膜。然后，这些膜合成肽聚糖。二吡啶甲酸钙还与发育中的前孔合并。角蛋白喜欢蛋白质形成孢子涂层。细菌降解后，孢子释放。发芽仅在适当的情况下发生。

Germination

The spore wall breaks during germination, and the new营养细胞forms. The breaking of the spore wall occurs through physical, chemical or radiation methods. This formed vegetative cell is then capable of growth and reproduction. The vegetative cell emerges as an outgrowth of the endospore during the germination.

What are Fungal Spores?

Fungal spores are of eukaryotic origin. Spores are present as reproductive structures in fungi. These spores are exospores and depending on different classes, the exospores have different names such asAscospores, Basidiospores,动物孢子等。真菌孢子是微观和不同size, shape, colour and the mode of release. The spores usually disperse through the air or as droplets. Some release during specific seasons or throughout the year.

Fungal spores are industrially important as they can lead to many fungal borne infections in plants. These include common plant pathogens such as辣椒灰和Cochliobolus heterostrophus.Some fungal spores act as skin allergens.

细菌内孢子和真菌孢子之间有什么相似之处？

• Both are microscopic structures.
• Both Bacterial Endospores and Fungal Spores are capable of reproduction and growth.

细菌内孢子和真菌孢子有什么区别？

Bacterial Endospores vs Fungal Spores
细菌内孢子是核细菌中存在的休眠结构。	Fungal spores are reproductive structures present in eukaryotic fungi.
Type of Spore
内孢子起源于内部。	Fungal spores originate to the outside. Hence, they are exospores.
Structure
内孢子的结构厚，带有孢子涂层。	Fungal spores are varied in size, shape and colour.
Presence of Dipocolinate
Dipocolinate is present in endospores.	Dipocolinate is absent in fungal spores.
Heat Resistance
在内孢子中，耐热性很高。	Heat resistance is Low in fungal spores.
Chemical and Radiation Resistance
Endospores are resistant to chemicals and radiation.	Fungal spores are less resistant to chemicals and radiation.
Examples
芽孢杆菌，梭菌，etc produce endospores.	曲霉，青霉，霉菌，酵母，产生真菌孢子。

概括– Bacterial Endospores vs Fungal Spores

Bacterial endospores and fungal spores are two special structures involved in reproduction and growth of bacteria and fungi respectively. Bacterial endospores exist as in built structures. When the bacteria undergo harsh conditions, a vegetative cell of the bacterium degrades, but the endospore survives. When the germination conditions are optimal, the vegetative cells form following sporulation. In contrast, fungal spores are exospores that can undergo reproduction when they release to the environment. This is the difference between bacterial endospores and fungal spores.
