Effect of mining activities on the rhizosphere soil bacteria of seven plants in the iron ore area

mycolabadmin

Iron ore mining damages soil and contaminates it with heavy metals, disrupting the beneficial bacteria that live around plant roots. This study examined seven plants growing in a mining area and found that each plant attracted different types of bacteria to survive the harsh conditions. Some bacteria help plants resist metal toxicity through various mechanisms. Understanding which bacteria naturally thrive in contaminated soils could help restore degraded mining areas.

Recent Advances and Developments in Bacterial Endophyte Identification and Application: A 20-Year Landscape Review

mycolabadmin

Bacterial endophytes are beneficial bacteria living inside plants that help them grow stronger, resist diseases, and even clean up polluted soil. Scientists have studied these helpful microbes for 20 years and discovered they can be identified using both traditional laboratory methods and advanced DNA technologies. These bacteria show promise for making farming more sustainable by reducing the need for chemical pesticides and helping crops survive droughts and other stressors.

Effects of Cordyceps militaris solid medium on the growth performance, immunity parameters and intestinal health of broilers

mycolabadmin

This research shows that a byproduct from growing Cordyceps militaris mushrooms can be used as a feed additive for chickens. When added at low doses to chicken feed, this mushroom byproduct improved the chickens’ growth, boosted their immune system, and created a healthier gut environment with beneficial bacteria. This offers a natural, non-antibiotic option for improving poultry farming.

Arbuscular Mycorrhizal and Trichoderma longibrachiatum Enhance Soil Quality and Improve Microbial Community Structure in Albic Soil Under Straw Return

mycolabadmin

Researchers found that combining two beneficial soil fungi—arbuscular mycorrhizal fungi and Trichoderma longibrachiatum—significantly improved poor quality albic soils when straw was returned to fields. The combined treatment increased soil pH, nutrients, and enzyme activity while promoting beneficial bacteria like Sphingomonas. This microbial approach offers farmers a sustainable, environmentally friendly way to restore degraded soils and improve agricultural productivity in regions with challenging soil conditions.

Soil microorganism colonization influenced the growth and secondary metabolite accumulation of Bletilla striata (Thunb.) Rchb. F.

mycolabadmin

Chinese ground orchid (Bletilla striata) is a medicinal plant whose growth and medicinal compound production depend heavily on soil microorganisms. Researchers found that different soil types harbor different beneficial microbes: sandy loam soils boost plant growth, while sandy clay soils increase medicinal compound concentration. Specific microbes colonize different plant parts, with some promoting growth in roots and tubers, while others enhance the production of militarine, a compound with potential anti-aging and cognitive benefits.

Tackling Conifer Needle Cast and Ash Dieback with Host-Derived Microbial Antagonists Exhibiting Plant Growth-Promoting Traits

mycolabadmin

Scientists discovered beneficial bacteria living on ash and pine trees that can fight two major forest diseases: ash dieback and needle cast. These bacteria not only kill the harmful fungi but also help trees grow stronger by improving nutrient absorption. This research offers promise for protecting European forests without relying on chemical fungicides, creating a more natural and sustainable approach to forest health.

Effects of a biotechnologically produced Pleurotus sapidus mycelium on gut microbiome, liver transcriptome and plasma metabolome of broilers

mycolabadmin

Researchers tested whether mushroom mycelium (the root structure of mushrooms) grown in large bioreactors could be used as a supplement in chicken feed as a sustainable alternative to traditional ingredients. Over 5 weeks, broilers received feed with 0%, 2.5%, or 5% mushroom mycelium, with no negative effects on growth, digestion, or overall health observed. The study suggests that this biotechnologically produced mushroom biomass is a safe and potentially sustainable feed ingredient for poultry production.

Morphological, Genetic, and Microbiological Characterization of Tuber magnatum Picco Populations from Alto Molise, Central-Southern Italy

mycolabadmin

This research studied Italian white truffles from the Molise region, one of Italy’s most important truffle-producing areas. Scientists examined 20 truffles from four different locations, analyzing their physical characteristics, genetic makeup, and the bacteria and fungi living inside them. They discovered a unique genetic pattern found only in Molise truffles and identified complex microbial communities that may help authenticate where truffles came from, helping prevent food fraud and protect truffle producers.

Multi-omics reveals novel forage advantages of Potentilla anserina Linnaeus in high-salt habitats

mycolabadmin

Potentilla anserina, a traditional Tibetan plant, can be grown as animal feed on salty, unused land. Researchers found that when the plant is fermented as silage, it becomes more nutritious and develops beneficial microbes that help it resist salt and drought. This makes it a promising sustainable feed option for livestock raised in areas with saline soils.

Inonotus hispidus Protects against Hyperlipidemia by Inhibiting Oxidative Stress and Inflammation through Nrf2/NF-κB Signaling in High Fat Diet Fed Mice

mycolabadmin

Inonotus hispidus is an edible mushroom that may help treat obesity and high cholesterol by reducing fat levels and inflammation in the body. In mice fed a high-fat diet, the mushroom improved cholesterol profiles, reduced liver damage, and promoted beneficial gut bacteria. The beneficial effects appear to work through activating the body’s natural antioxidant defenses and reducing inflammation-causing proteins.
