Abstract
Industrialization and indiscriminate discharge of sewage being implicated in environmental pollution is responsible for the release of micropollutants which over time is expected to alter the physiology and metabolic pathways of microbiota native to the environment. This study was undertaken to track antibiotic resistant genes in industrial wastewater. Heterotrophic bacterial count indicated a vast abundance of culturable bacteria (76-232.66× 104 Cfu/ml). Hydrocarbon utilizing bacteria count ranged between (91.66 - 111.6×104 Cfu/ml). Antibiotic resistant bacteria isolates from industrially impacted wastewater identified by Sanger’s sequencing included Bacillus lichenforminis (KF737353.1), Alkanindiges sp. 5-0-9 (LT158291.1), Bacillus thuringiensis (MK875170.1, MK517632.1 EU697392.1) Bacillus altitudinis (KY777585.1), Bacillus cereus (KR185830.1) and Bacillus subtilis (MK124647.1). This study infers that industrial effluent is a potent reservoir for antibiotic resistant bacteria of environmental and public health concerns.
Highlights
Sewage consists of substances either organic or inorganic which most often mediate into solution in the aqueous phase and due to their characteristic size are referred to as ꞌmicropolllutantsꞌ
Microbiological Parameters of Wastewater The total heterotrophic bacterial count (THBC) ranged from 76 – 105 Cfu/ml results for the wastewater samples are presented in Figure 1, Figure 2 shows result for coliform bacterial count (Cfu/ml) across the study locations, the results ranged from 40 – 239 Cfu/ml
This study examined the microbiological parameters of effluents from industries located at Trans Amadi Industrial Layout, Port Harcourt, Rivers State, with the aim to ascertain the incidence of antibiotics among the bacterial isolates
Summary
Sewage consists of substances either organic or inorganic which most often mediate into solution in the aqueous phase and due to their characteristic size are referred to as ꞌmicropolllutantsꞌ. Sewage frequently deviates from the natural balance with respect to composition and possess a degraded quality owing to introduction of xenotic substances. Pharmaceutical waste, hospital waste and agricultural waste are contributing significantly to the swell in antibiotics levels in sewage [3,4,5,6,7]. Waste from these sources and products can trigger genomic modification for antibiotic resistance, as these eventually end up in the environment
