Sesame, Pistachio, and Macadamia Nut: Development and Validation of New Allergenic Systems for Fast Real-Time PCR Application.
Food allergy is a worldwide health problem that concerns infants to adults. The main health risk for sensitised individuals is due to the presence of traces of allergens as the result of an accidental contamination during food processing. The labelling of allergens such as sesame, pistachio, and macadamia nut on food products is mandatory according […]
Palladium nanoparticles dispersed on functionalized macadamia nutshell biomass for formic acid-mediated removal of chromium (VI) from aqueous solution.
Driven by the need for sustainably sourced catalysts and the use of reaction systems that generate environmentally benign by-products, the present study aimed to deposit stable, dispersed palladium (Pd) nanoparticles on the modified surfaces of granular macadamia nutshell (MNS) biomass for catalytic reduction of hexavalent chromium (Cr(VI)) to trivalent chromium (Cr(III)). Through wet impregnation with […]
The Equilibrium, Kinetics, and Thermodynamics Studies of the Sorption of Methylene Blue from Aqueous Solution Using Pulverized Raw Macadamia Nut Shells.
In this study, the potential for pulverized raw macadamia nut shell (MNS) for the sequestration of methylene blue from aqueous media was assessed. The sorbent was characterized using scanning electron microscopy for surface morphology, functional group analysis was performed with a Fourier-transform infrared spectrometer (FT-IR), and Brunauer-Emmett-Teller (BET) isotherm was used for surface area elucidation. […]
Genetic Structure of Wild Germplasm of Macadamia: Species Assignment, Diversity and Phylogeographic Relationships.
Macadamia is an Australian native rainforest tree that has been domesticated and traded internationally for its premium nuts. Common cultivars rely upon a limited gene pool that has exploited only two of the four species. Introducing a more diverse germplasm will broaden the genetic base for future crop improvement and better adaptation for changing environments. […]
Microwave Pyrolysis of Macadamia Shells for Efficiently Recycling Lithium from Spent Lithium-ion Batteries.
To reduce harm to the environment and human health and improve economic benefits, the large number of spent lithium-ion batteries that have been produced in recent years need to be reasonably recycled. The purpose of this article is to study a new method, microwave pyrolysis of the shells of macadamia nuts, for efficient recycling of […]
Metaphycus macadamiae (Hymenoptera: Encyrtidae)–a biological control agent of macadamia felted coccid Acanthococcus ironsidei (Hemiptera: Eriococcidae) in Hawaii.
A new species of encyrtid wasp, Metaphycus macadamiae Polaszek & Noyes sp. n., (Hymenoptera: Encyrtidae: Encyrtinae) is described as a solitary endoparasitoid of the invasive macadamia felted coccid, Acanthococcus ironsidei (Hemiptera: Eriococcidae) in Hawaii. This parasitoid is native to Australia, and the species description is based on material collected from a Macadamia integrifolia Maiden & […]
Draft genome of the husk spot pathogen, Pseudocercospora macadamiae, infecting macadamia.
Pseudocercospora macadamiae causes husk spot in macadamia in Australia. Lack of genomic resources for this pathogen has restricted acquiring knowledge on the mechanism of disease development, spread and its role in fruit abscission. To address this gap, we sequenced the genome of P. macadamaie. The sequence was de novo assembled into a draft genome of 40 Mb, […]
Macadamia Nuts Oil in Nanocream and Conventional Cream as Skin Anti-Aging: A Comparative Study.
Background: The effect of an active substance in a dosage form can be influenced by the different method of preparation. Nanotechnology has been used widely in all aspects including drug delivery system. Nanocream is one of the cosmetic dosage forms to improve the absorption of active substances on the skin. Aim: The study was to […]
Spatio-temporal Spread of Abnormal Vertical Growth of Macadamia in Australia Informs Epidemiology.
Australian macadamia production is threatened by a disorder known as abnormal vertical growth (AVG), for which the aetiology is unknown. AVG is characterized by vigorous upright growth and reduced lateral branching, flowering and nut set that results in over 70% yield loss annually. Six commercial macadamia orchards were surveyed in 2012 and again in 2018 […]
Genome-wide association studies for yield component traits in a macadamia breeding population.
Background: Breeding for new macadamia cultivars with high nut yield is expensive in terms of time, labour and cost. Most trees set nuts after four to five years, and candidate varieties for breeding are evaluated for at least eight years for various traits. Genome-wide association studies (GWAS) are promising methods to reduce evaluation and selection cycles […]
