AI Article Synopsis
- The study evaluated the effects of magnesium hydrogen phosphate (MHP) as an alternative phosphorus source for juvenile far eastern catfish, comparing it to three traditional sources: monocalcium phosphate (MCP), dicalcium phosphate (DCP), and tricalcium phosphate (TCP).
- Fish fed MHP achieved similar weight gain and feed efficiency to those fed MCP, while outperforming DCP, and showed higher plasma phosphorus levels than those fed TCP and control diets.
- Overall, MHP demonstrated comparable performance to MCP in terms of growth and feed utilization, indicating its potential as a viable phosphorus supplement in aquaculture.
Article Abstract
The present study was conducted to investigate a supplemental effect of magnesium hydrogen phosphate (MHP, MgHPO4) as an alternative phosphorus (P) source on growth and feed utilization of juvenile far eastern catfish (Silurus asotus) in comparison with three conventional P additives (monocalcium phosphate (MCP), dicalcium phosphate (DCP) and tricalcium phosphate [TCP]) as positive controls. A basal diet as a negative control was prepared without P supplementation and four supplemental P sources were added at the level of 2%. Five groups of 450 fish having mean body weight of 11.3 g following 24 h fasting after three week adaptation period were randomly distributed into each of 15 tanks (30 fish/tank). Fish were hand-fed to apparent satiety twice a day for 8 weeks. Fish fed MHP had weight gain (WG), protein efficiency ratio and specific growth rate comparable to those fed MCP. Fish fed MHP and MCP had feed efficiency (FE) significantly higher (p<0.05) than those fed DCP. Fish groups fed control and TCP showed the lower FE than the other groups which was significantly different (p<0.05) from those of fish fed the other diets. Survival rate was not significantly different (p>0.05) among treatments. Fish fed control had the lowest hematocrit, which was significantly different (p<0.05) from that of fish fed MHP. Fish fed MCP and MHP had plasma P higher (p<0.05) than fish fed the other diets. Relative efficiencies of MCP, DCP and TCP to MHP were found to be 100.5 and 101.3%, 92.0 and 91.6%, and 79.1 and 80.9% for WG and FE, respectively. P availability was determined to be 88.1%, 75.2%, 8.7%, and 90.9% for MCP, DCP, TCP, and MHP, respectively. Consequently, MHP recovered from wastewater stream showed that as an alternative P source its performance was comparative with MCP on growth and feed utilization of juvenile far eastern catfish.

Magnesium hydride (MgH) is a promising material for solid-state hydrogen storage due to its high gravimetric hydrogen capacity as well as the abundance and low cost of magnesium. The material's limiting factor is the high dehydrogenation temperature (over 300 °C) and sluggish (de)hydrogenation kinetics when no catalyst is present, making it impractical for onboard applications. Catalysts and physical restructuring (e.

Biodegradable magnesium (Mg) implant generally provides temporary fracture fixation and facilitates bone regeneration. However, the exact effects of generated Mg ions (Mg), hydrogen gas (H), and hydroxide ions (OH) by Mg degradation on enhancing fracture healing are not fully understood. Here we investigate the degradation of Mg intramedullary nail (Mg-IMN), revealing the generation of these degradation products around the fracture site during early stages.

To develop a direct production process for TiH powder from TiO, the reduction of TiO using Mg in molten MgCl - KCl salt under a high hydrogen chemical potential was investigated. The reduction of nano-sized TiO powder was conducted at 973 - 1073 K under an Ar or Ar and 10% H mixed gas atmosphere when the mass ratios of Mg to feed and salt to feed were 1.14 - 2.

The preparation of a solid dosage form containing bacteriophages, which meets pharmaceutical requirements and ensures long-term stability of the phage effect, is significant for implementing phage therapy in practice. A commonly used method for processing phages into a solid form is freeze-drying into a (so-called) freeze-dried cake; however, to date there have been no studies examining the pharmacopeial parameters of freeze-dried tablets with bacteriophages. In this study, we describe the preparation and properties of freeze-dried tablets containing a cocktail of purified pseudomonal bacteriophage DSM 33593 from the genus Pbunavirus and staphylococcal bacteriophage DSM 33473 from the genus Kayvirus (10 PFU/tablet) as the active ingredient.

Soil contamination with toxic heavy metals [such as aluminum (Al)] is becoming a serious global problem due to the rapid development of the social economy. Although plant growth-promoting rhizo-bacteria (PGPR) are the major protectants to alleviate metal toxicity, the study of these bacteria to ameliorate the toxic effects of Al is limited. Therefore, the present study was conducted to investigate the combined effects of different levels of (5 ppm and 10 ppm) of accession number of MT123456 on plant growth and biomass, photosynthetic pigments, gas exchange attributes, oxidative stress and response of antioxidant compounds (enzymatic and nonenzymatic), and their specific gene expression, sugars, nutritional status of the plant, organic acid exudation pattern and Al accumulation from the different parts of the plants, which was spiked with different levels of Al [0 µM (i.
