A. Describe the difference between an obligate and facultative aerobe. An obligate aerobe is a microorganism that must have oxygen for growth and will grow at the top of the test tube. A facultative aerobe prefers oxygen but it is not necessary for growth. Many of these microorganisms will grow at the top of the tube‚ but will also be dispersed throughout as well. B. Discuss the temperature requirements of the organisms (you grew) in this lab. Both Staphylococcus epidermis and Lactobacillus acidophilus

Recovering SUSTAINABLE Water from Wastewater AUDREY D. LEVINE UNIVERSITY OF SOUTH FLORIDA‚ TAMPA TA K A S H I A S A N O UNIVERSITY OF CALIFORNIA‚ DAVIS Society no longer has the F luxury of using or water supplies to be sustainable‚ water only once. the rate at which water is withdrawn from water sources needs to be in balance with the rate of renewal or replenishment. At the same time‚ water quality must also be sustainable or recoverable. In nature‚ precipitation replenishes surface water

improve our state of living specifically in terms of economics. Site suitability rating systems are to be used in assessing the environmental parameters of the sites. The biophysical parameters such as salinity‚ temperature‚ dissolved oxygen‚ pH‚ turbidity‚ water current and depth of the site are to be measured.

INTRODUCTION: The research topic is based upon the impact of the abiotic factors on community properties in the aquatic ecosystems of bith La Vega and Caroni Swamp. The abiotic factors to be included ate salinity‚ turbidity‚ dissolved oxygen‚ phosphates‚ nitrates‚ pH‚ and temperature. Aqautic abiotic factors have become a prudent issue in these ecosystems affecting the abundance and distribution of species as well as feeding relationships as seen in food webs and food chains. In order to try to solve
