1. Introduction
1.1. Background
Microbiological and biotechnological solutions to global problems
such as water and food shortages as well as water resources
pollution are required. As many global issues, for example
improving crop quality and productivity as well as public health
and wastewater management, have more acute consequences in
the developing world, this paper emphasizes the role of
biotechnological advances for developing regions where food
production using recycled pre-treated wastewater is of interest.
The world is over-populated in many geographical areas
causing considerable strain on natural resources such as freshwater.
Since water resources are limited, particularly in dry climatic
regions, wastewater treatment and subsequent recycling is a viable
alternative (Asano, 1994). Treated wastewater can be used for
agricultural land irrigation, aquaculture, landscape irrigation,
urban and industrial applications, recreational and ecosystem
