Valorizing sunflower processing byproducts for a sustainable bioeconomy: Fungal fermentation and characterization of hulls and screens

JSFA reports, Volume 5, Issue 6, Page 266-277, June 2025.
Abstract Background Sunflower hulls (SFH) and screens (SFS) are byproducts of sunflower seed processing with limited alternative applications. This study investigates the submerged fermentation of SFH and SFS by Aureobasidium pullulans‐(Ap), Trichoderma reesei‐(Tr), Aspergillus oryzae‐(Ao), Neurospora crassa‐(Nc), and Aspergillus niger‐(An) to alter ...

Response of broiler chickens to diets containing different levels of sodium with or without microbial phytase supplementation

Journal of Animal Science and Technology, 2019
Phytate induced excessive mineral excretion through poultry litter leads to poor performance and environmental pollution. Exogenous microbial phytase supplementation to poultry diets reduce the environmental ...

Methanol‐Free Protein Expression in Komagataella phaffii With Magnetic or Non‐Magnetic Heating

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
We describe a methanol‐free protein expression platform for Komagataella phaffii. This platform uses a HSP70 promoter induced by magnetic or non‐magnetic heating. ABSTRACT Komagataella phaffii is among the most widely used expression systems, with methanol‐inducible promoters being preferred for protein expression due to their stringent regulation and ...

Properties of Chick Intestinal Phytase

Poultry Science, 1972
Abstract Optimum conditions for the assay of chick intestinal phytase were studied on native and commercial “technical” and “purified” preparations. Activity was near maximum when the substrate concentration was about 0.25 mM sodium phytate (1.5 mM phytate P) in the presence of 1.0 mM MgCl2 and pH about 7.2.

Simplex and multiplex CRISPR/Cas9‐mediated knockout of grain protease inhibitors in model and commercial barley improves hydrolysis of barley and soy storage proteins

Plant Biotechnology Journal, Volume 23, Issue 6, Page 2418-2428, June 2025.
Summary Anti‐nutritional factors in plant seeds diminish the utilization of nutrients in feed and food. Among these, protease inhibitors inhibit protein degradation by exogenous proteases during digestion. Through conventional and selection‐gene‐free genome editing using ovules as explants, we used simplex and multiplex CRISPR/Cas9 for studying the ...

Review on Desirable Microbial Phytases as a Poultry Feed Additive: Their Sources, Production, Enzymatic Evaluation, Market Size, and Regulation

International Journal of Microbiology
Poultry’s digestive tract lacks hydrolytic phytase enzymes, which results in chelation of dietary minerals, vital amino acids, proteins, and carbohydrates, phytate-phosphate unavailability, and contamination of the environment due to phosphorus ...

Effect of phytase on phosphorous balance in 20-kg barrows fed low or adequate phosphorous diets

Animal Nutrition, 2020
The effects of phytase on phosphorus (P) digestibility are well established. However, there are few studies that report P balance, particularly when phytase is used in diets that have adequate or deficient P.

Genome Editing Technologies to Improve Health‐Related Phytocompounds in Crops

Food Frontiers, Volume 6, Issue 3, Page 1271-1286, May 2025.
ABSTRACT Due to rapid global population growth and the resulting significant increase in food demand, the world is facing an epidemic of malnutrition. Although yield improvement remains one of the main targets of breeding programs, much attention is being paid to the nutritional aspects of crops, including nutrients and bioactive compounds that are ...
