A sustainable and effective bioprocessing approach for improvement of acid phosphatase production and rock phosphate solubilization by Bacillus haynesii strain ACP1

Scientific Reports, 2022
There is indeed a tremendous increase in biotechnological production on a global scale, more and more innovative bioprocesses, therefore, require to perform ideally not only in a small lab- but also on large production scales. Efficient microbial process

Agronomic efficiency of partially acidulated and granulated Arraias phosphate rock [PDF]

Revista Brasileira de Ciência do Solo
Natural phosphate rocks (PR) are characterized by low phosphorus (P) solubility in water. Acidulation is the normal method to raise P solubility of these materials, however, it increases the cost and causes operational issues.

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1677-1691, April 2026.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Corrosion behavior of zirconia in acidulated phosphate fluoride [PDF]

Journal of Applied Oral Science, 2016
The corrosion behavior of zirconia in acidulated phosphate fluoride (APF) representing acidic environments and fluoride treatments was studied.Zirconia rods were immersed in 1.23% and 0.123% APF solutions and maintained at 37°C for determined periods of time.

Differences in Recycled Amendment Phosphorus Solubility and Transport When Interfaced to Soils of Dissimilar Characteristics

Soil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Increasing phosphorus (P) fertilizer use efficiency from bio‐based waste products (i.e., recycled amendments) requires promoting a larger proportion of bioavailable P in soil for plant uptake. Therefore, this study aimed to elucidate how recycled amendment P solubility and movement vary when interfaced with soils of contrasting characteristics.

Optimization of Photocatalytic Conversion of Lignocellulosic Waste: A Green Route to Long‐Chain Alcohols

Chemistry–Methods, Volume 6, Issue 1, January 2026.
Tall oil fatty acids are first converted into their corresponding soaps, which subsequently undergo decarboxylation in the photoreactor to yield the respective alkenes. Through hydration with sulfuric acid, these alkenes are further transformed into the corresponding alcohols, which can serve as valuable precursors in downstream processes for the ...

Evaluation of phosphate sources using ruminal fiber transit kinetics methodology

Frontiers in Animal Science
IntroductionSince the low phosphorus content is one of the reasons for the low degradation of fiber in roughage such as pasture and by-products, fiber transit kinetics can be an important tool to evaluate differences in digestion depending on phosphorus ...

Acidification and Sodium Citrate Modulate the Yield, Functionality, and Acceptability of Artisanal Asadero Cheese Made From Raw Milk

Journal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
Artisanal asadero cheese is a fresh pasta filata–type product whose functional quality depends on the control of acidification and mineral balance of the casein matrix. The objective of this study was to evaluate the effect of different technological routes: (1) fermentation, (2) direct acidification, and (3) mineral adjustment with sodium citrate on ...
