A Gram-negative rod was isolated from the blood cultures of an 84-year-old man with foot cellulitis. The bacterium was first identified as Sphingobacterium spiritivorum on the basis of standard assimilation tests. However, sequencing analysis of its 16S rRNA genes and whole genome hybridization studies with other related bacteria showed that this isolate belongs to a so far undescribed species of Sphingobacterium, close to S. mizutae. This bacterium was susceptible to most of the antibiotics tested, including glycopeptides, but was resistant to aminoglycosides and polymyxins. Treatment with amoxicillin-clavulanate cured the infection.

The kitchen waste and garden waste (KW-GW) co-composting system provides an effective method for recycling these two types of municipal solid waste; however, further improvements are needed to enhance bioconversion performance. This study investigates a novel composting additive, calcium polypeptides (CPPs), derived from waste animal and plant proteins, which can enhance the bioconversion capacity of biomass in the KW-GW co-composting system. As a pH regulator and an available nitrogen source, CPPs significantly increase the compost matrix pH, prolong the thermophilic phase, and reduce emissions of exhaust gases such as CH, NO, NH, and HS by 52.

Introduction: Extreme water temperature affects the well-being of all aquatic animals, including fish. Higher temperatures can lead to the generation of reactive oxygen species (ROS), which can induce oxidative stress and negatively impact fish health and well-being. This study investigated the protective effects of seaweed extract on growth, antioxidant status, inflammatory responses, and gut microbiota to gain a better understanding of the acclimatization ability of Nile tilapia, in response to oxidative stress caused by high water temperatures.

Article Synopsis
- A disease called wilt is a big problem for growing bananas worldwide, and traditional ways to fight it aren't working as well anymore.
- Scientists are studying a special bacteria called NMS02 S296 from resistant banana plants to see how it can help prevent this disease.
- The researchers found that NMS02 S296 has many helpful genes and can stop the growth of the wilt-causing fungus, showing promise as a natural way to protect banana crops.
