After the construction, the field will be lichened.

施工,使地面长满地衣。

However, Bacillus licheniformis was aerotolerant anaerobe, in a shape of ellipse and swelled in the middle with production of Arginine hydrolase.

地衣芽孢杆是兼性厌氧，芽孢呈椭圆形中间膨大，能产生精氨酸双水解酶。

Fragments of the thallus containing both phycobiont and mycobiont cells may also grow into new lichens, a from of asexual reproduction.

地衣的碎裂片中，如含有藻类和真共生时，也可长成独立植株，这是一种无性的生殖形式。

The lichen is a typical example of the intergrowth among the microorganism, it is fungi, blue bacterium or homobium of the alga.

地衣就是微生物间共生的典型例子，它是真和蓝藻类的共生体。

Reproduction in lichens may be asexual by soredia (algal cells enclosed by fungal hyphae) or by sexual fungal spores, which can survive only if some algal cells are also present.

地衣可以利用粉芽（真丝包裹藻类胞）进行无性生殖利用真孢子进行有性生殖。
