Opis:: The increase in number of antibiotic resistant bacteria poses a serious environmental and health problem. The development of microbial resistance is intensified by the widespread use of antibiotics in medicine, veterinary, farming and aquaculture. The wastewater treatment plants receiving the wastewater from hospitals, slaughterhouses, farms, pharmaceutical industry and houses can be potential places of spreading of antibiotic resistant genes. The molecular mechanisms of the bacterial resistance, including the horizontal transfer of antibiotic resistant genes and the presence of mobile genetic elements can be responsible for the increase in antibiotic resistance during wastewater treatment. The aim of this study was to analyze the phenomenon of bacterial resistance to selected β-lactam antibiotics (ESBL) by detecting the genes that determine this resistance. The PCR method was used to analyze the occurrence of two genes: blaPER and blaGES in wastewater samples. It was revealed that the resistant/total bacteria ratio was significantly higher in the effluent compared with the influent wastewater. Genes blaPER and blaGES were isolated from several strains predominating in both aeration tank (5% and 20% respectively) and effluent wastewater (15% and 12% respectively).

Opis:: Downy mildew (Sclerospora graminicola (Sacc) Schroet.) of pearl millet [Pennisetum glaucum (L.) R.Br.] is a devastating disease that has greatly led to grain yield loss in Nigeria. A field experiment was carried out in 2010 at Bakura (Zamfara State) and Zaria (Kaduna State) in North West Nigeria. The objective of this paper was to evaluate downy mildew resistance in some pearl millet using Complete Randomized Block Design. Four resistant male varieties (PEO5532, SOSATC88, P1449 and DMR15) and four susceptible female varieties (BDP1, MOP1, LCIC9702 and PEO5984 were used in this study. The resistant varieties were crossed with the susceptible varieties using North Carolina design 11 for the mating to form sixteen (F1) hybrids. The F1 hybrids were further evaluated along with their parents for downy mildew resistance, grain yield and other agronomic traits (such as: Plant height, panicle height, number of tillers per plant, panicle diameter and number panicles per plot). The resistant male parents were found to be susceptible while none of the hybrids was resistant to downy mildew. However, the degree of incidence and severity of downy mildew disease defer in the two locations. The hybrids exhibited tolerance to downy mildew disease and their yields were higher than their parents. The analysis of variance (one tale ANOVA or which one?) showed highly significant difference among parents and hybrids for all agronomic characters except disease severity and number of tillers per plant. Location × genotype interaction effects were only significant for grain yield and number of panicles per plot.

Tytuł:: Diversified role and applications of marine actinomycetes in the field of biology

Opis:: Actinomycetes are the most profitable and biotechnologically valued prokaryotes representing the genera consisting of Streptomyces, Arthrobacter, Actinomyces, Cornyebacterium, Micrococcus, Micromonospora and other diverse species of microorganisms. Actinomycetes represent a group of one of the most powerful secondary metabolite producers which possess a wide range of biological activities. Streptomyces, an important genus under actinomycetes, alone serves as the huge producer of a number of biologically active molecules. This genus possesses a huge potential of synthesizing various different and novel active metabolites. Due to the gradual reduction of the chances of isolation of novel compounds within Streptomyces coming from terrestrial environs resulting in the increase of resistant pathogenic microorganisms, marine actinomycetesmay form a platform for novel drug synthesis, which in-turn may form an extraordinary tool for combating a wide range of resistant microbes. The role of marine actinomycetes extends to diverse fields such as antibiotic production, production of antibacterial and antifungal compounds, synthesis of enzymes and enzyme inhibitors, synthesis of anticancer drugs and various other lifesaving molecules. Marine actinomycetes also play an important role in biofouling and nanoparticle synthesis. Thus speakingsuccinctly, marine actinomycetes are biologically very important as they serve their useful purpose in various fields of biology.
