Environmental ecological niche

Over 200 000 species of fungi have been characterised. The fungi are extremely responsive to environmental pressures and exhibit a high capacity to adapt to and colonise a variety of ecological niches. They can be found growing anywhere between the high mountains to the abyssal depths and from dry, polar regions to the hot, humid tropics. 

Once released in the environment by means of human faeces or animal dejection, enterococci are able to colonise different ecological niches because of then-resistance to adverse environmental conditions. Enterococci are widely spread in nature, in soil, food, on plant and vegetables and surface water. They are used as indicators of faecal pollution in environmental waters (Godfree et al. 1997).

In the second case, the impact of consumer demand is less direct, but it still remains important. The main actor in this case is the customer-firm, whose attention paid to the environmental aspects, both regarding its own image and the willingness to exploit some ecological niches of the market, has a direct influence on its choices. The situation in this case presents a stronger complexity. In many cases, the company which introduces a new environmental product also has to invent the applications for its use. This occurs particularly...
