Sideróforos: uma resposta dos microorganismos [PDF]

Quimica Nova, 2002
Siderophores (from the Greek: "iron carriers") are defined as relatively low molecular weight, ferric ion specific chelating agents elaborated by microorganisms growing under low iron stress. The role of these compounds is to scavenge iron from the environment and to make this essential chemical element available to the microbial cell.

Safracin B as a Synthetic Linchpin: From Natural Product to Drug Intermediate and Beyond

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
Safracin B is employed as a key precursor for the streamlined preparation of cyanosafracin B and safracin A. Careful tuning of the reaction parameters affords these derivatives in high efficiency, and full nuclear magnetic resonance signal assignments are established for the complex safracin frameworks.

Biofertilization of canola seeds with Peribacillus simplex and Paenibacillus polymyxa bacteria increases tocopherol content

JSFA reports, Volume 6, Issue 7, Page 252-255, July 2026.
Abstract Background Biofertilization with plant growth‐promoting bacteria (PGPB) is a reliable strategy to reduce the amounts of chemical fertilizers applied to crops. Nevertheless, the effects of biofertilizers on plant chemical constituents that influence food quality and human health should be evaluated.

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 783-791, May 2026.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

Photoacclimation of cryptophytes and diatoms to light variability in the Western Antarctic Peninsula

Journal of Phycology, Volume 62, Issue 2, Page 643-665, April 2026.
Abstract Meltwater stratification during austral summer along the rapidly warming Western Antarctic Peninsula (WAP) exposes coastal phytoplankton to sudden light shifts. Such variability is thought to modulate phytoplankton dynamics, yet the photoacclimation capacity of Antarctic phytoplankton, especially cryptophytes, remains unclear.
