GREENHOUSES AND POND LINERS
Role of pond lining in dynamics of sulfur recycling bacteria in Pacific White Shrimp, Penaeus vanammei grow out culture ponds Plastic lining ponds provide better management and healthier environmental conditions, and sulfur cycling bacteria can be used as an indicator of pond environmental conditions. The present investigation, developed by researchers from Universities Bharathidasan and Navsar and the Aquatic Animal Health and Environment Division Central Institute of Brackishwater Aquaculture (CIBA) in India, compares observations on the trend of total heterotrophs, total vibrios, and the sulfur cycling

process of mineralization. Microorganisms are involved in the production and breakdown of organic matter and nutrient recycling in aquatic environments. Heterotrophic bacteria oxidize organic matter, whereas the autotrophic nitrifying and sulfur
bacteria oxidize problematic compounds like ammonium, nitrite, or sulfide, respectively (Moriarty, 1997). Sulfur-reducing bacteria (SRB) and sulfuroxidizing bacteria (SOB) are predominately involved in the reduction and oxidation of sulfates and APRIL-MAY 2021
