Industrial pollution is responsible for 45% of the overall pollution in the Pasig River. Approximately 315 of the 2,000 or more factories that is located in the river basin are identified as the main polluters of the river, discharging an average of 145 tons of biochemical oxygen demand (BOD) per day. This was recognized by defining the suspended solids in their treated and untreated waste-waters. It is said that, the textile and food manufacturing industries are the utmost water polluters. The pollution rate is anticipated to decrease by 2% a year because of inadequate commercial land accessible along the river and the bigger requirements for container transport. Domestic liquid waste adds another 45% of the pollution load in the Pasig River.…show more content…
Untreated waste-waters that comes from the remaining 88% of the population run through canals and esteros into viaducts that leads into the Pasig River. approximately 148 tons d-1 of BOD is added into the Pasig River coming from the sewage outlets that is disseminated along its banks. The Metropolitan Waterworks and Sewerage System (MWSS) was hindered in its task because they lack monetary fund. Because it is also accountable for the water supply in the metropolis, it is supposed to give water supply more priority than sewage management. Solid waste only add up to 10% of the pollution in the Pasig River. Even though it is visible, rubbish gives only 30 tons of BOD per day. Nevertheless, the solid waste that is being discharged on the water surface hinders the penetration of sunlight to the life of the plants that are located underwater and the solid waste that descends to the river bed smother the aquatic life that exists in the river.

There are all other opinions on the nomenclature of some of the streptococci in the identification systems in the UK and USA. There are now 99 known species of Streptococcus, and many of these are related with disease in humans and animals (Thompson et al., 2013). Streptococci are Gram positive cocci (spherical or ovoid) that most of the time occur in pairs and chains. Streptococci are facultatively anaerobic and catalase negative (Hardie, 1986). Carbohydrates are being metabolized fermentatively; lactic acid is the vital metabolite. Streptococci yield the enzyme leucine aminopeptidase (LAP), this is also called leucine arylamidase (SMI,
