Soy protein concentrate (SPC), as a source, is widely used to replace partial fishmeal (FM) in aquafeeds, especially for carnivorous fish. This study investigated the effects of FM replacement by SPC juvenile pearl gentian grouper. The fish were fed with diets containing six levels (SPC 0, 15, 30, 45, 60, and 75) 6 weeks. At end feeding trial, average body weight gain (BWG), specific growth ratio (SGR), (WGR) had highest values diet followed that 0 while 75 lowest (P < 0.05). Fish 15 30...

ABSTRACT The production of short-chain fatty acids (SCFAs) through anaerobic fermentation is a significant strategy for the resource utilization excess sludge (ES). However, limitations low temperatures and slow ES hydrolysis rates have resulted in less than optimal volatile acid (VFA) accumulation. This study reports new method improving low-temperature VFA using peracetic (PAA) pretreatment elucidates underlying mechanisms. results showed that at 10 °C, PAA significantly enhanced release...

This study aims to acetylate Rehmannia glutinosa polysaccharides by acetic anhydride method, optimize process parameters and evaluate their antioxidant activity. With the degree of substitution(D_s) as a criterion, effects reaction time, anhydride-to-polysaccharides ratio temperature were investigated. Process optimized single-factor experiment response surface methodology. The infrared spectroscopy(IR) scanning electron microscopy(SEM) proved successful acetylation employed preliminarily...

Abstract Jujube is susceptible to biotic and abiotic adversity stresses resulting in abnormal phenotypic defects. Therefore, phenotype fruits should be removed during postharvest sorting increase added value. An improved maximum horizontal diameter linear regression (MHD‐LR) method for size grading of jujube prior detection defects was developed. The accuracy the MHD‐LR model 95%, with an error only 0.95 mm. In addition, a detecting established. It can effectively accurately classify seven...

The changes in cotton leaf characteristics are closely related to the spider mites’ damage level. Extracting distinguishable features of leaves is an effective method identify However, it faces enormous challenges for classification due various factors, such as illumination intensity, background complexity, shooting angle and so on. A recognition model proposed, which trained through transfer learning with two-stage rate from 0.01 0.001 based on MobileNetV1. experiments demonstrate that deep...
