Abstract:

The effect of exposing cockroaches to entomopathogenic bacteria isolated from the diseased specie was examined based on established parameters. Cockroaches were collected from residential areas in Akure metropolis in Nigeria using a bread and beer trap, brought to the laboratory, housed in wooden cages with wire nettings, provided with starch-based food and sterile water. Collected cockroaches were observed for the onset of possible disease symptoms amongst the population for several weeks. Resulting moribund and dead cockroaches were aseptically picked, surface sterilized and homogenized insi

ABSTRACT The number and disposition of flagella harbored by eubacteria are regulated by a specific trait successfully maintained over generations.

The characterization of a spontaneous ifm mutant of B. subtilis, displaying diverse degrees of cell flagellation in both liquid and solid media, raised the question of how the ifm locus governs the number and assembly of functional flagella.

Abstract:

Fermented soybean meal (FSM) is an important feed material that can replace fish meal to solve the shortage of animal protein. To improve the utilization of FSM, we optimized the co-fermentation conditions of soybean meal using Bacillus subtilis and Enterococcus faecium and studied the effects of replacing fish meal with different proportions of FSM on serum antioxidant indices and gut microbiota (GM) composition of crucian carp (Carassius auratus). Our results showed that the co-fermentation of soybean meal was the most effective when the ratio of B. subtilis X-2 and E. faecium X-4 was 2:3, g

From biotic factors chocolate spot (Botrytis fabae Sard.) is the major fungal disease hampering faba bean production in Ethiopia.). It is a highly prevalent and destructive disease, causing yield loss up to 61% on a susceptible and 34% on tolerant faba bean genotypes i

Micoscopic observations revealed that strain GIMV4.0001T produced long, straight chains of cylindrical spores, and chemotaxonomic data confirmed that it belongs to the genus Streptomyces.
