Description
Summary:Waste stabilization ponds were studied near the 1200 inhabitant village of Santo Tomas Atzingo in Mexico where corn agriculture and cattle raising were the main occupations. Chromobacterium and Flavobacterium were among the types of bacteria that played an important role in this type of sewage treatment as both could degrade many nitrogenous organic and inorganic compounds. In addition, Chromobacterium could degrade aromatic compounds and herbicides and Flavobacterium members had halotolerant characteristics. The species Flavobacterium meningosepticum was, however, an opportunistic pathogen to man, causing infections which were usually attributed to contaminated hospital equipment and solutions. Twelve samples were taken from June to December 1982 and strains of both bacteria genus were successfully isolated. It was concluded that retention time of sewage in ponds should be increased if the effluent was to be used for irrigation, otherwise the residual bacteria would take nitrogen from the soil. Irrigation was advised only for crops whose produce would not be in direct contact with the irrigation water.
