AI Article Synopsis
- Lecanicillium fungicola is a pathogen that causes dry bubble disease in white button mushrooms (Agaricus bisporus), leading to significant economic losses for growers.
- Researchers used GC/MS techniques to analyze volatile compounds emitted from infected and control mushroom cultures to find potential early warning signs of the disease.
- Compounds like β-copaene, β-cubebene, and α-cedrene appeared with disease symptoms, while infected mushrooms showed high levels of β-barbatene and another unidentified diterpene, indicating a defense response to the infection.*
Article Abstract
Lecanicillium fungicola is a pathogen of the commercial white button mushroom (Agaricus bisporus) and is the causal agent of dry bubble disease, which can cause severe economic losses to mushroom growers. Volatile compounds were measured by GC/MS techniques over pure cultures of mycelia on agars, over microcosms of growing mushrooms, and over harvested mushrooms to identify compounds that might give an early warning of the disease. The mushroom strain tested was Agaricus bisporus, strain Sylvan A15; either deliberately infected with L. fungicola or water as a control. Over microcosms, the appearance of β-copaene, β-cubebene, and α-cedrene coincided with, but did not precede, the earliest visual signs of the disease. Mushrooms with dry bubble symptoms also had high levels of β-barbatene and an unknown diterpene (UK 1821). Over some harvested mushroom sets, high levels of cis-α-bisabolene developed as a defence reaction to infection.

Experimental assessment and analysis of mass transport limiting current density in water vapor-fed polymer electrolyte membrane electrolyzers.

Department of Mechanical Engineering, Carnegie Mellon University, Pittsburgh, PA, USA.
Polymer electrolyte membrane water electrolyzers (PEMWEs) are a critical technology for efficient hydrogen production to decarbonize fuels and industrial feedstocks. To make hydrogen cost-effective, the overpotentials across the cell need to be decreased and platinum-group metal loading reduced. One overpotential that needs to be better understood is due to mass transport limitations from bubble formation within the porous transport layer (PTL) and anode catalyst layer (ACL), which can lead to a reduction in performance at typical operating current densities.

Molten metal catalysts for methane pyrolysis and dry reforming are becoming recognized for their potential in decarbonization efforts. Their use in bubble column reactors facilitates continuous operation by allowing the produced carbon to float to the surface for removal. While most reported molten metals produce low-value amorphous carbon or graphitic sheets containing some metals, our study introduces a Cu-In alloy that selectively produces high-purity carbon nanofibers.

This study aimed to explore the combined effects of micro-nano bubble water drip irrigation and different phosphorus (P) application rates (P0: 0 kg·hm; P1: 86 kg·hm; P2: 172 kg·hm; P3: 258 kg·hm) on maize growth, soil phosphorus dynamics, and phosphorus use efficiency to optimize irrigation and P fertilizer use efficiency. Through a field column experiment, the impact of micro-nano bubble water drip irrigation on maize plant height, stem diameter, leaf SPAD values, biomass, and yield was evaluated. The results showed that (1) irrigation methods significantly affected maize growth indicators such as plant height, stem diameter, and root dry weight.

Article Synopsis
- The study focuses on producing syngas from six bamboo biomass species in Mizoram, India, using a double-tapered reactor for efficient gasification.
- Various pre-processing methods and reactor conditions (temperature, particle size, and feeding rates) are examined to enhance syngas yield, with specific attention to factors like bed dynamics and carbon conversion efficiency.
- Results indicate that higher temperatures lead to increased hydrogen and carbon monoxide production, while optimal particle size (1.18 mm) improves gas yield and efficiency, highlighting the potential of biomass energy as a sustainable resource.

All over the world, the oceans are the final destination of sewage transported by river estuaries, rainwater and other coastal discharges. The risks to human health related to direct contact with water and consumption of contaminated fish are well known, but little is known about the potential for atmospheric exposure to pollutants and pathogens from contaminated seawater. The release of microbial particles from the sea into the atmosphere occurs mainly by the eruption of rising bubbles through the sea surface microlayer (SML) or by sea spray.
