Biodegradation of oil-derived hydrocarbons by marine actinobacteria: A systematic review.

The intensive use of oil and its derivatives is related to a greater frequency of accidents involving the release of pollutants that cause harmful effects on ecosystems. Actinobacteria are cosmopolitan and saprophytic microorganisms of great commercial interest, but because they are predominantly found in soil, most research into the products of this phylum's metabolism has focused on this habitat. Marine actinobacteria exhibit unique metabolic characteristics in response to extreme conditions in their habitat, which distinguishes them from terrestrial actinobacteria.

Aspects of brucellosis vaccination in Maranhão state.

Bovine brucellosis is a zoonosis of great economic and public health relevance. Understanding the epidemiological aspects of this disease is a determining factor to help developing effective strategies and supporting decision-making processes. The aim of the present study is to carry out a situational vaccination diagnosis against brucellosis in Maranhão State's cattle in order to identify challenges set for vaccination operations and to help the Official Veterinary Service to plan health interventions.

Nursing care for parents who have experienced fetal demise: integrative review.

Objectives: to identify scientific evidence regarding nursing care for parents who have experienced grief following fetal demise.

Methods: an integrative review of original studies was conducted across six databases. The studies were classified according to the level of evidence.

An equatorial mid-Atlantic Ocean archipelago as nursery area for the cookiecutter shark: Investigating foraging strategies of neonates through bite mark inferences.

This study delves into the foraging ecology of the cookiecutter shark (Isistius brasiliensis) in the Saint Peter and Saint Paul Archipelago (SPSPA), assessing bite marks on pelagic fishes collected between March and September 2018. Examination of 200 individuals from five species revealed the shark's predilection for targeting adult fish, ensuring efficient removal of energy-rich tissue layers. However, a notable exception is Thunnus albacares, preyed on predominantly during its juvenile stage, possibly due to vertical spatial segregation.

Morphological diversity of actinobacteria isolated from oil palm compost (Elaeis guineensis).

Composting is a natural process of decomposition of organic matter that occurs by the action of microorganisms such as fungi, bacteria, and actinobacteria. The actinobacteria are present throughout the process due to their resistance to different environmental conditions. They are Gram-positive, filamentous bacteria with a high capacity for producing secondary metabolites of biotechnological importance.
