Spore‐Based Water‐Resistant Water‐Responsive Actuators with High Power Density

Advanced Materials Technologies, 2019
AbstractActive materials and surfaces that are less intrusive and more compatible with humans and their environment are critical for robotic applications. Humidity‐ and water‐responsive materials are emerging as versatile alternatives to commonly used actuators in robotic systems, due to ease of actuation with humidity gradients and pervasiveness of ...

Effect of Water's Microwave Power Density Memory on Fungal Spore Germination

Electro- and Magnetobiology, 1994
The effect of absorbed microwave power in water on germination of some fungal spores was seen. Water samples were exposed to 2.71 GHz microwave at varying incident power density. Incident and absorbed power by water were determined using power sensor and meter.

Loss of optical density in bacterial spores induced by partial cell irradiation.

Radiation research, 1977
Spores of Bacillus megaterium strain 14581 (ATCC) were subjected to partial cell irradiation in an attempt to localize the structure controlling the loss of extinction. The results indicate that damage by ionizing radiation to a barrier about 200 A thick and 450 A from the surface of the spore will induce loss of optical density in spores resuspended ...

Spore density and root colonization of vesicular-arbuscular mycorrhizas in tropical soil

Transactions of the British Mycological Society, 1987
Spore density and mycorrhizal colonization were studied in four plant species within two sites in a lowland rain forest for a period of 17 months. Although the dominant VA endophyte and plant species examined in each site were different, the variation in spore numbers and mycorrhizal colonization in both sites showed a similar pattern.

Reduction of Spore Density of Plasmodiophora brassicae in Soil by Decoy Plants

Journal of General Plant Pathology, 2001
The severity of clubroot (Plasmodiophora brassicae) on Chinese cabbage was reduced by growing plants such as oats, spinach and leafy daikon prior to Chinese cabbage in pot experiments. Resting spore densities of P. brassicae in the soil were 29–62%, depending on the pervious crop, as compared to unplanted control plot after ploughing under the ...

Density-dependent insect-mold interactions: effects on fungal growth and spore production

Mycologia, 2005
Larvae of saprophagous insects often have been suspected of being competitors of filamentous fungi on decaying organic matter, which negatively influence mold development. Of interest, the role of insects in determining fungal growth and the onset of sporulation largely has been ignored.

High-density spore production of a B. cereus aquaculture biological agent by nutrient supplementation

Applied Microbiology and Biotechnology, 2009
Previous studies have demonstrated the efficacy of our Bacillus cereus isolate (NRRL 100132) in reducing concentrations of nitrogenous wastes and inhibiting growth of fish pathogens. In vivo efficacy and tolerance to a range of physiological conditions in systems used to rear Cyprinus carpio make this isolate an excellent candidate for aquaculture ...

The Use of Density Gradient Centrifugation for the Separation of Germinated from Nongerminated Spores

Journal of Applied Bacteriology, 1972
S ummary : The density gradient centrifugation of a suspension of spores of B. subtilis 8057 on both sucrose and renografin gradients gave 2 distinct fractions.

Ganoderma basidiospore germination responses as affected by spore density, temperature and nutrient media

Tropical Plant Pathology, 2017
The present study investigated the axenic basidiospore germination of Ganoderma australe, G. mastoporum and G. philippii at three spore densities in five nutrient media encompassing a range of carbohydrate complexity, in combination with sawdust and/or ethanol as medium additives.

Factors Affecting Arbuscular Mycorrhizal Fungi Spore Density in the Chilean Mediterranean-Type Ecosystem

Journal of Soil Science and Plant Nutrition, 2019
Arbuscular mycorrhizal fungi (AMF) are highly important for plant communities in dry or seasonally dry ecosystems, such as the South American Mediterranean-type ecosystem (MTE), considered a biodiversity hotspot. While AMF hold potential for sustainable MTE management and conservation, they have been under investigated on this ecosystem and little is ...
