Food production must be increased to respond the demands of a growing world population and challenges posed by climate change. Higher temperatures, unpredictable rainfall weather patterns, changes in seasons, occurrences drought extreme events will exert greater strain on agriculture. Emerging evidence suggests that change cause shifts food yield loss due more hostile patterns. A key strategy adapt changing is development promotion underutilised crop species. The today relies small number...

Solid waste disposal, particularly of plastic and rubber, significantly impacts the environment human health; thus, encouraging consumers to u sustainable alternatives is essential ensure a resilient future. In recent decades, bio-based material research has primarily focused on bioplastics and, accordingly, current knowledge alternative materials (such as biorubber) fragmented, with consumer misconceptions posing key challenge. This paper provides comprehensive overview fundamentals...

This study addresses the challenge of enhancing gamma-aminobutyric acid (GABA) content in soy sauce through optimized fermentation condition. Using a multiple starter culture, consisting Aspergillus oryzae strain NSK, Bacillus cereus KBC and Tetragenococcus halophilus KBC, incubation conditions including percentage bacterial inoculum (10, 15 20 %), pH (3, 5 7) agitation speed (100, 150 200 rpm) were Response Surface Methodology (RSM). Under optimal (20 % inoculum, 7 stirring at 100 rpm),...

Globally, farming systems are mostly dominated by monoculture, which has the advantage of profitability at expense ecological systems. Recent years have witnessed an increasing momentum in global efforts to deploy sustainable agriculture practices that mimic processes, with agroecology forefront. In addition aspect, also encompasses economic and social aspects targeting whole food system. Transformative been recognized as a stepping stone achieving several Sustainable Development Goals...

Abstract Worldwide, many mangrove species are experiencing significant population declines, including Rhizophora apiculata , which is one of the most widespread and economically important in tropical Asia. In Malaysia, there has been an alarming decline R. populations driven primarily by anthropogenic activities. However, lack genetic demographic information on this hampered local efforts to conserve it. To address these gaps, we generated novel for based 1,120 samples collected from 39...

The polymorphisms of Waxy (Wx) microsatellite and G-T single-nucleotide polymorphism (SNP) in the Wx gene region were analyzed using simplified techniques fifteen rice varieties. A rapid reliable electrophoresis method, MetaPhor agarose gel (MAGE), was effectively employed as an alternative to polyacrylamide (PAGE) for separating alleles. amplified products containing ranged from 100 130 bp length. Five alleles, namely (CT)(10), (CT)(11), (CT)(16), (CT)(17), (CT)(18) identified. Of these,...

Purpose The purpose of this paper is to identify the strain oyster mushroom (OM) Pleurotus sapidus cultivated in a local (commercial) farm, and generate total quality index (TQI) on using different modified atmosphere packaging (MAP) gas mixtures. Design/methodology/approach A phylogenetic tree was constructed MEGA software specific P. grown farm. effects MAP fresh fruiting bodies identified were determined under three conditions: high carbon dioxide (HCP: 20 per cent CO 2 , 15 O ), low...

ABSTRACT: An experiment was conducted to investigate the effects of different shading regimes [i.e., 60% (heavy), 30% (moderate), and 0% (control)] on 25 traits associated with morphological features, photosynthetic gas exchange agronomic characteristics winged bean (Psophocarpus tetragonolobus), an underutilized protein-rich legume from tropics. Collectively, 80% studied variables displayed significant differences (P<0.05) between at least two shade treatments. Shading generally showed...

While it is crucial for developing countries like Malaysia to achieve self-sufficiency in rice (Oryza sativa L.), equally critical be able produce high-quality rice, specifically fragrant which demands are often met through importation. The present study was aimed at high-yielding a timely and cost-effective manner. A marker-assisted backcross (MABC) approach optimised introgress the fragrance gene (fgr) into two Malaysian varieties, MR84 MR219, within years utilising less than 50 molecular...
