The surface microlayer (SML) is the dividing border between air and water surface. It has physical, chemical biological properties which are distinctly from subsurface layer (SSL) waters. As its unique place air- water, SML remained in a distinct research corner. Surface characterized by capacity to accumulate of organic compounds specially proteins, carbohydrates lipid. presence such as energy...

In addition to being an integral part of the planet’s nitrogen cycle, bacterially facilitated nitrification is a process of great commercial importance in the wastewater treatment, aquaculture and agronomy industries. Twelve distinct species of heterotrophic bacteria, belonging to the genera Bacillus, Pediococcus and Lactobacillus, were isolated from BiOWiSH’s commercially available water treat...

Increase in the use of herbicides agricultural soil can cause multiple antibiotic resistance potential pathogens that undermine therapy. The study shows antimicrobial susceptibility aerobic heterotrophic bacteria and fungi isolated from soils polluted with different herbicides. A total sixteen (16) bacterial twenty-three (23) fungal isolates were subjected to sensitivity test (AST) using Kirby-...

The objective of the present study was to determine the shelf life of ready-to-eat cooked chicken breast fillets (shredded) stored in atmospheres that were modified with different concentrations of CO2 and to establish a relationship between the concentration of this gas and bacterial growth. The samples were divided into 7 groups with different packaging conditions: aerobiosis, vacuum, and 10,...

Photosynthetic microbial mats are sources of microbial diversity and physiological strategies that reflect the physical and metabolic interactions between their resident species. This study focused on the diversity and activity of polyhydroxyalkanoate-producing and -degrading bacteria and their close partnership with cyanobacteria in an estuarine and a hypersaline microbial mat. The aerobic het...

Aerobic granules were cultivated in a sequencing batch reactor (SBR). COD and ammonia nitrogen removal rate were 94% and 99%, respectively. The diameter, settling velocity and SVI10 of granules ranged from 2 to 5 mm, 80 to 110 m/h and about 40 mL/g, respectively. Freezing microtome images, DO concentration profiles by microelectrode, distribution of bacteria and EPS by confocal laser scanning m...
