"Impact of Untreated Brewery Effluent on Bacteriological Characteristic of Agricultural Soil" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-6 | Issue-3, April 2022, pp.1408-1414, URL: https://www.ijtsrd.com/papers/ijtsrd49673.pdf

This research was conducted to evaluate the impact of untreated brewery effluent on the bacteriological characteristic of agricultural soil. This is to ascertain the suitability of untreated brewery effluent for irrigation purposes. Untreated brewery effluent was aseptically collected from Intafact brewery, Onitsha, Anambra State, Nigeria., while agricultural soil was obtained from a maize farm in Onitsha. Five kilograms of the soil sample was treated with 200 ml of the effluent in a pot experiment and allowed for 80 days. The bacteriological characteristic of the effluent and soil samples (treated and untreated) was determined by estimating the total bacterial count, total coliform count, fecal coliform count, Pseudomonas count, Rhizobial count and Clostridium count. Results obtained showed that the untreated brewery effluent had total bacterial count of 5.2 × 103cfu/ml, total coliform count of 0.5× 103cfu/ml, Pseudomonas count of 0.7 × 103cfu/g and zero fecal coliform, Rhizobium and Clostridium counts. The total bacterial count, total coliform count, Pseudomonas count, rhizobial count and Clostridium count for the untreated and treated soil samples were 10.8× 103cfu/g and 22.8× 103cfu/g, 7.2× 103cfu/g and 11.4× 103cfu/g, 0.9 × 103cfu/g and 2.5 × 103cfu/g, 0.4× 103cfu/g and 0.73× 103cfu/g, 1.2 × 103cfu/g and 8.0 × 103cfu/g respectively. A total of 34 bacterial organisms belonging to ten different genera - Pseudomonas, Bacillus, Azotobacter, Streptococcus, Staphylococcus, Rhizobium, Proteus, Enterobacter, Klebsiella and Serratia were isolated from all the samples analyzed. While Enterobacter sp. occurred most in the effluent sample, Bacillussp predominated in the untreated soil sample. Rhizobium and Pseudomonas count were significantly higher (p-value < 0.05) in the treated soil sample. This study showed that untreated brewery effluent enhanced the growth of plant growth promoting bacteria, hence, can serve efficiently as irrigation water.
