DEGRADATION

This essay studies the impacts of human activities on the decline of the environment and on nature in a bid to criticise the arbitrariness of the use of nature’s resources. This essay also examines the beauty of nature to enhance the protection and preservation of nature. This essay discusses the relationship of man with his environment by highlighting the harmony nature possesses. Through the use of poetry, this essay elucidates on aspects that have been covered by authors, but not by poets, reflecting the importance of poetry on nature. The method of research employed in this study is eco-criticism, and the primary data is Niyi Osundare’s The Eye of the Earth, from which selected poems are used. The analysis of the selected poems shall undergo line by line analysis and exploring the literary devices that enhance the main purpose of this essay. The results of the analysis are illustrations of nature decline as a result of human’s irrational use, and therefore the beauty of nature is tampered with. These results give an opinion on how the environment should be treated, adding that the preservation of nature will improve the living standards of humanity.

Microbial degradation of emulsion paints poses significant challenges in industrial and environmental settings, often leading to discoloration, structural breakdown, and reduced durability of coated surfaces. Among the key microbial agents, Bacillus spp. and Escherichia coli have been identified for their enzymatic capabilities and metabolic versatility in degrading paint components such as binders, pigments, and additives. These bacteria utilize organic compounds in paint as carbon sources, contributing to biodeterioration through acid production, biofilm formation, and enzymatic hydrolysis. This study presents a comparative analysis of the physiological and growth responses of Bacillus spp. and Escherichia coli over a 21-day incubation period under ambient laboratory conditions. Key parameters monitored included pH, optical density (OD), temperature, and total viable count (TVC), providing insights into microbial adaptation and proliferation trends. For Bacillus, the pH remained stable at 7.0 until Day 7, then declined to 6.0 by Day 14, suggesting increased metabolic activity and acid production, followed by a slight recovery to 6.2. OD values fluctuated, peaking at Day 14 (0.40), indicating active biomass accumulation, while TVC rose progressively from 0.675 ×10⁷ CFU/mL to 9.60 ×10⁷ CFU/mL by Day 21, reflecting robust growth. Temperature varied modestly between 24°C and 27°C, with no apparent inhibitory effect. In contrast, E. coli
exhibited a sharper pH decline from 6.8 to 5.6 by Day 14, consistent with its fermentative metabolism. OD decreased steadily from 0.51 to 0.26, suggesting reduced cell density or viability over time. However, TVC increased significantly, from 0.5 ×10⁷ CFU/mL to 8.35 ×10⁷ CFU/mL, indicating sustained proliferation despite declining OD. Temperature ranged from 26°C to 30°C, with peak microbial activity observed at higher temperatures. The results highlight distinct metabolic and growth profiles between the two species. Bacillus demonstrated resilience and biomass recovery, while E. coli maintained high cell counts despite reduced optical density. These findings underscore the importance of multi-parameter monitoring in microbial ecology and have implications for bioprocess optimization, environmental microbiology, and industrial fermentation systems.
