Use of multispecies (Nannochloropsis oceanica, Artemia franciscana, and Arbacia nigra) approach to assess the quality of marine water from Callao Bay, Peru

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 7, 2025

Multi-species tests in bioassays offer a holistic view of the ecosystem's response to toxicity, as different species display varying sensitivities pollutants. This research aimed assess ability toxicity tests' distinguish contamination levels, examine site-specific effects, and investigate seasonal variability. Using multispecies approach (Nannochloropsis oceanica, Artemia franciscana, Arbacia nigra), evaluated marine water quality from Callao Bay Peru across four sampling areas (Naval School: PA1, Peruvian Marine Institute: PA2, Pier: PA3, San Lorenzo Island: PA4). These species, with sizes morphologies, are relevant systems ideal for testing, contributing broader environmental impact discussions. To conduct bioassays, evaluations were performed fall, winter, spring, summer. Brine shrimp displayed variations values, notable mortality rates during winter. Nannochloropsis oceanica was most sensitive showing moderate seasons. Areas impacted by pollution sources, such wastewater maritime traffic, exhibited highest levels (PA3 fluctuations underscore need consider local conditions when assessing organism sensitivity seawater contaminants. Additionally, they reveal complex interplay between factors, quality, responses ecosystems.

Investigating the effect of chitosan on the expression of P5CS, PIP, and PAL genes in rapeseed (Brassica napus L.) under salt stress

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Feb. 18, 2025

Chitosan, a non-toxic and biodegradable compound, enhances plant growth secondary metabolite production, presenting innovative approaches to mitigating stress. Salinity, common abiotic stress, significantly impairs development. This study investigates the effects of chitosan on physiological, biochemical, gene expression responses salt-stressed Brassica napus L. exposed NaCl concentrations 0, 50, 100, 150 mM. Chitosan was applied as foliar spray at 5 10 mg/L. The research focuses changes in P5CS, PIP, PAL genes roots shoots napus, revealing notable alterations, particularly PIP under saline conditions. also observed enhanced enzyme activity, increased chlorophyll proline levels, iron, potassium, nitrogen content. These findings demonstrate chitosan's potential improve resilience salt By modulating enhancing physiological responses, presents promising solution for tolerance salinity, with valuable implications agricultural practices.

Amino Acid and Carotenoid Profiles of Chlorella vulgaris During Two-Stage Cultivation at Different Salinities

Bioengineering, Journal Year: 2025, Volume and Issue: 12(3), P. 284 - 284

Published: March 13, 2025

Microalgae are valuable sources of bioactive compounds. However, their production requires strategies to enhance metabolic responses. This study explores how Chlorella vulgaris responds different salinity conditions using a two-stage cultivation strategy, assessing the change in amino acid and carotenoid content on microalgae over time. First, were cultivated under optimal conditions, followed by exposure levels (150 mM 300 NaCl). Growth kinetics, nutrient uptake, biochemical composition analysed, revealing distinct salinity-induced Similar specific growth rates achieved across all assays, while nitrate removal improved phosphate uptake decreased. Amino profiling showed significant declines several compounds also presented declining trends, although moderate mitigated degradation key pigments. Principal component analysis identified high correlations between acids carotenoids contents, forming groups with similar variations. These findings contribute better understanding response C. vulgaris, offering insights for biotechnology applications. By optimising could compound retention, supporting development sustainable microalgae-based products.

Received: 18 January 2025; Revised: March Accepted: 6 Published: April 2025 Abstract: Microalgae are versatile platforms producing biofuels high-value metabolites, such as lipids, proteins, carotenoids. Numerous stress strategies have been adopted improve microalgal cultivation biomolecule yield. This review examines how conventional factors (light salinity) unconventional treatments (electric field treatment) influence growth metabolite accumulation. Light intensity, spectrum, photoperiod significantly affect photosynthesis, biomass yield, carotenoid biosynthesis, with moderate intensities found enhance efficiency. However, excessive levels may induce photoinhibition. Salinity induces activation antioxidant systems lipid accumulation, optimizes biofuel properties. high salinity can impair the microalgae. In review, we focused on electric treatment a potential strategy enhancing productivity, representing major novelty study. Unlike traditional that primarily adaptive metabolic shifts, offers unique an understudied approach modulating cellular physiology. Electric technology energy-efficient method stimulating cell differentiation pigment production while reducing environmental effects. Integrating these be attractive controlling over metabolism, supporting sustainable scalable biorefinery applications.
