The present study evaluated the effects of dietary microbial phytase on the growth and gut health of hybrid tilapia (Oreochromis niloticus ♀×Oreochromis aureus ♂), focusing on the effect on intestinal histology, adhesive microbiota and expression of immune-related cytokine genes. Tilapia were fed either control diet or diet supplemented with microbial phytase (1000 U/kg). Each diet was randomly assigned to four groups of fish reared in cages (3×3×2 m). After 12 weeks of feeding, weight gain and feed conversion ratio of tilapia were not significantly improved by dietary microbial phytase supplementation. However, significantly higher level of P content in the scales, tighter and more regular intestinal mucosa folds were observed in the microbial phytase group and the microvilli density was significantly increased. The adhesive gut bacterial communities were strikingly altered by microbial phytase supplementation (0·41

Article Synopsis
- This review highlights recent advancements in engineering thermostable phytase through genetic modification and immobilization techniques over the last seven years.
- Genetic modifications have improved the enzyme's thermostability and functionality, while immobilization methods have helped retain 50-60% of its activity at temperatures above 50°C.
- Phytase is essential in the food and feed industries, as it reduces phytate content to enhance nutritional value in flour and poultry feed, making it a robust option for high-temperature applications.

The need for sustainable and safe alternatives to antibiotic growth promoters has driven researchers to explore organic acids (OAs) inclusion in broiler diets. Citric acid (CA), a notable OA, has emerged as a promising alternative due to its various physiological benefits, including improved nutrient digestibility, antioxidant properties, and enhanced weight gain. Despite the improved growth performance, the feed conversion ratio (FCR) does not seem to be consistently affected by CA inclusion.

Introduction: The Longan fruit tree of the Vietnam Mekong Delta is grown in raised beds to improve water drainage during the rainy season and can live as long as 100 years.
Objective: This research explores the extent to which the soil microorganisms as well as soil physical and chemical properties of these raised beds degrade over a period of 60 years under traditional management practices.
Materials And Methods: Raised bed topsoil samples at depths of 0-20 cm were obtained from four different Longan orchards raised bed age groups: group 1) 15-25 years (L1-L5); group 2) 26-37 years (L6-L10); group 3) 38-45 years (L11-L15); and group 4) 46-60 years.

Deciphering effects of sealed environment on phosphorus (P) availability and microbial community during water-logged composting is an essential but underestimated theme. Research targets are to unveil divergences in P fractions and bacterial landscapes between breathable and sealed systems using molecular and statistical tools. Water-logged composting with sealed system enhanced P availability, with soluble reactive P in overlying water notably increasing from 1.

The impact of chemical fertilizers on soil microbial communities is well acknowledged. This study assesses the influence of various phosphorus sources on soil bacterial composition, abundance, and Phosphorus Cycle Gene Abundance. Three phosphorus sources (natural phosphate rock, triple super phosphate (TSP), and chemical fertilizer NPK) were field tested following two rice cultivation cycles.
