and evaluation of the nutritional value of various hydrolyzed feather meals and comparison of their effect on performance and carcass characteristics of broilers.

In the current study, the nutritional value of various hydrolyzed feather meals (HFM) was investigated in two separate experiments (an and an experiment). The experiment was based on a completely randomized design with five replications and seven treatments including (1) Raw feather meal (RFM), (2) HFM by autoclave (Au-HFM), (3) Fermented feather meal (FFM) by (Bl-FFM), (4) FFM by (Bs-FFM), (5) FFM by (An-FFM), (6) FFM by  +  +  (Co-FFM), and (7) HFM by an enzyme (En-HFM). The highest pepsin-pancreatin and apparent ileal CP digestibility were observed in Co-FFM, and the lowest amount belonged to RFM (P < 0.

Life cycle assessment and technoeconomic analysis of biofuels produced from polyculture microalgae cultivated in greywater.

This study evaluated the environmental and economic impacts of substituting synthetic media with greywater for cultivating microalgae in the biofuel production process. Life cycle assessment (LCA) and technoeconomic assessment (TEA) were employed to compare the impacts of two scenarios - one containing bold's basal (BB) media and another containing greywater as growth mediums for microalgae cultivation. Scenarios 1 and 2 mitigated 1.

Exploring effects of carbon, nitrogen, and phosphorus on greywater treatment by polyculture microalgae using response surface methodology and machine learning.

The microalgae-based wastewater treatment is a promising technique that contribute to achieving sustainable development goals (SDGs), such as SDG-6, "Clean Water and Sanitation". However, it is strongly influenced by the initial composition of wastewater. In this study, the impact of initial organics and nutrient concentration on the removal of total organic carbon (TOC), total carbon (TC), ammonium (NH), total nitrogen (TN), and phosphate (PO) from greywater using native polyculture microalgae was explored.
