Healthy land

Land has a wide variety of uses: agricultural, residential, industrial, and recreational. Microbes play a key role in the terrestrial ecosystem, providing symbiotic relationships with plants. Human use of land has led to the exhaustion of nutrients in soils, contamination of land, and a reduction in biodiversity. Applying our knowledge of microbes will be essential in restoring the biodiversity of affected ecosystems. Greater research into how microbes impact human life on land could all have a positive impact, by increasing crop production, repurposing areas of land and improving microbial biodiversity in soil, land, and water.

Bee hives found to be ‘living immune systems’ that protect bees

Researchers have discovered honey beehives act as ‘living immune systems’ that help protect the bee colony, their offspring, and food supplies from disease.   In a remarkable example of insect engineering each part of the hive is ‘built in’ strategically across different compartments of the hive.

    How plants unwittingly help fungal pathogens

    Infecting a maize plant is no simple task for a fungal pathogen such as Ustilago maydis. A group of researchers has now uncovered how the fungus detects that it has successfully entered its host. This signal triggers changes in fungal growth.

    Could plywood provide a better home for oil-degrading microbes?

    The material used to support microbial biofilms could influence their potential role in treating water generated during oil production. Researchers examined whether different supporting materials affect the formation, abundance, and composition of biofilms inside a 14-hectare constructed wetland treating oil-produced water.

    Virus-based tool opens a faster route to studying cowpea genes

    Genome sequencing of cowpea has provided researchers with numerous candidate genes, and genetic transformation has enabled studies of traits such as drought and heat tolerance. A new study reports sustained gene silencing across seven cowpea varieties and demonstrates the system’s utility for investigating jasmonate regulation during leafminer infestation.

Textile and food waste co-digestion boosts methane yields

Anaerobic co-digestion of textile waste with food waste (FW) could turn two stubborn waste streams into renewable methane while reducing landfilling and incineration. A study examined mono- and co-digestion of cotton, polycotton, and wool with FW under mesophilic conditions, testing substrate-to-inoculum (S/I) ratios of 0.5 and 1 and multiple feedstock mixing ratios.
