Document Summary
Growing microbes: to study microbes it is necessary to grow them. How do we grow microbes: provide them with their required: Environmental components is incubated: nutritional components are supplied in the culture media, environmental conditions conditions under which the inoculated media, to grow microbes require satisfaction of both their nutritional and. Sub optimal rates won"t grow as fast as it normally could in the. Incomplete satisfaction of nutritional and / or environmental requirements usually results in sub-optimal (reduced) growth rates environmental laboratory. Variety of macro-elements / macro-nutrients: c, o, h, n, s and p, also k, mg, ca and fe. Micro-nutrients: mn, an, co, mo, ni and cu. Source of electrons: from light or chemical reactions, metabolizing organic compounds, such as sugars. Microbes require a balanced mixture of nutrients. Short supply of essential nutrient(s) will limit growth. If absence is prolonged organism will die. Growing microbes in the lab: first need to:
