Machine learning optimization of environmental factors influencing biomass and nutritional composition in local algal species

Royal Society Open Science, Год журнала: 2025, Номер 12(4)

Опубликована: Апрель 1, 2025

Algae are recognized for their potential in biofuel production due to high biomass yield, protein and lipid. This study investigates the influence of pH, temperature, light intensity, colour CO2 concentration on biochemical composition five algal genera (Chlorella, Botryococcus, Chlamydomonas, Tetraselmis Closterium). Algal samples were isolated from aquatic environments KPK-Pakistan cultured under controlled conditions. Environmental variables systematically varied: concentration. Biochemical analyses revealed ranging 0.2 2.1 g l-1, lipids 7.2-24.5% proteins 8-49.5%, with optimal conditions pH 7, 30°C, red light, 3000 lux 9% CO₂. Machine learning was applied optimize environmental conditions, random forest (RF) identified as most effective model. A novel metric, W_new, combining performance error metrics, facilitated robust model evaluation hyperparameter tuning. The model's feature importance analysis ranked CO₂ influential factors. RF achieved R² scores 0.686 (training) 0.534 (validation), demonstrating strong predictive performance. integrates experimental computational approaches, providing a detailed framework optimizing cultivation. We highlighted utility machine enhancing lipid productivity, advancing sustainable biofuel.

This study aimed to develop a conceptual framework for plastic bottles management in Small Island Developing State (SIDS), Mauritius. The environmental implications associated with the disposal or treatment of PET (polyethylene terephthalate) and PLA (Polylactic acid) were investigated from life-cycle perspective. analysis was based on 14 impact categories 4 damage using IMPACT 2002+. following scenarios assessed; Scenario 1: Landfilling bottles, 2: 3: Composting bottles. functional unit defined as 1000 units (PET/PLA) 1 contributed 35.5% more than 2 3 human health. Scenarios together 21.1% higher that scenario towards ecosystem quality. Towards climate change, showed 100% contribution while 20% 30% contribution, respectively. Regarding resources, 78.5% lower 1. Hence, recycling rate recommended be increased by 60%, remaining 40% sent landfill site. For it 50% composted, recycled 10% Mare Chicose
