The operation of cracking Macadamia nuts is the most critical and delicate step for achieving high-quality kernels. The nuts, usually at high moisture content, are dried to a recommended moisture, before cracking, in a process that takes from 3 to 4 weeks at the expense of large energy consumption. The present paper examines the basis of shell rupture which is needed for the development of new methodologies or techniques to reduce the drying period and to obtain a more efficient kernel extraction ...

Abstract The selection of fungi resistant to currently used fungicides and the emergence of new pathogenic species make the development of alternative fungus‐control techniques highly desirable. Photodynamic antimicrobial chemotherapy (PACT) is a promising method which combines a nontoxic photosensitizer (PS) with visible light to cause selective killing of microbial cells. The development of PACT to treat mycoses or kill fungi in the environment depends on identifying effective PS for the different ...

Candida albicans is a human pathogenic fungus mainly affecting immunocompromised patients. Resistance to the commonly used fungicides can lead to poor treatment of mucosal infections which, in turn, can result in life-threatening systemic candidiasis. In this scenario, antimicrobial photodynamic treatment (PDT) has emerged as an effective alternative to treat superficial and localized fungal infections. Microbial death in PDT is a consequence of the oxidation of many cellular biomolecules, including ...

With the emergence of antifungal- and antibiotic-resistant microorganisms, aPDT has been suggested as a promising microbial control strategy. The treatment is based on a combination of visible light, a photosensitizer (PS), and molecular oxygen. Illuminating the PS with adequate light in the presence of oxygen will result in the generation of abundant reactive oxygen species (ROS), ...
