Methanogens and what they tell us about how life might survive on Mars.

Space exploration and research are uncovering the potential for terrestrial life to survive in outer space, as well as the environmental factors that affect life during interplanetary transfer. The presence of methane in the Martian atmosphere suggests the possibility of methanogens, either extant or extinct, on Mars. Understanding how methanogens survive and adapt under space-exposed conditions is crucial for understanding the implications of extraterrestrial life.

Identification of genotypic variants and its proteomic mutations of Brazilian SARS-CoV-2 isolates.

The second wave of COVID-19 caused by severe acute respiratory syndrome virus (SARS-CoV-2) is rapidly spreading over the world. Mechanisms behind the flee from current antivirals are still unclear due to the continuous occurrence of SARS-CoV-2 genetic variants. Brazil is the world's second-most COVID-19 affected country.

Development of top-dressing automation technology for sustainable shrimp aquaculture in India.

Globally, the shrimp farming industry faces increasing challenges and pressure to reduce the broken shrimps and maintain a healthier pond environment. Shrimps lack an adaptive immune system to combat invading pathogens due to an imbalance in beneficial gut microbiota. The use of top-dressing agents like probiotics and pond optimizes is an alternative strategy to improve the innate immune system leading produce disease-free shrimp in international markets.

Growth-associated catabolic potential of Acetoanaerobium sticklandii DSM 519 on gelatin and amino acids.

Acetoanaerobium sticklandii DSM 519 is a hyperammonia-producing anaerobe that catabolizes proteins and amino acids into organic solvents and volatile acids via the Stickland reactions. However, the specific growth rate and metabolic capability of this organism on proteins and amino acids are not yet known. Therefore, the present study was intended to evaluate its specific growth rate and metabolic potential on gelatin and amino acids in the experimental media.

Structure, Function and Evolution of Clostridium botulinum C2 and C3 Toxins: Insight to Poultry and Veterinary Vaccines.

Clostridium botulinum group III strains are able to produce cytotoxins, C2 toxin and C3 exotoxin, along with botulinum neurotoxin types C and D. C2 toxin and C3 exotoxin produced by this organism are the most important members of bacterial ADP-ribosyltransferase superfamily. Both toxins have distinct pathophysiological functions in the avian and mammalian hosts.
