Ebook "Defence against bioterrorism: Methods for prevention and control" examines microorganisms and their possible use in forensics, i.e. as possible detection tool that could enable fast and precise detection of possible treats. A number of plant derived components are also discussed as possible agents in bioterrorism attacks, and in relation to infectious disease pathology. Another integral part is food safety, especially in terms of large food supply chains, like airline caterings, institutionalized kitchens etc.

Ebook "Advances in food mycology (Advances in experimental medicine and biology, Volume 571)" was attended by some 35 participants, drawn from among food mycology and related disciplines around the world. The workshop was highly successful, with papers devoted to media and methods development in food mycology, as is usual with these workshops. Particular emphasis was placed on the fungi which produce mycotoxins, especially their ecology, and through ecology, potential control measures.

Ebook "Ane’s encyclopedic dictionary of general and applied entomology" has been written keeping in view the fact that different terminology employed in teaching and researchers on different aspects of studies on insects and their management is found in scattered sources. Moreover, in the last 3-4 decades, many developments have been made especially in economic entomology. An attempt has been made to present the terminology in entomology and pest management in the most authentic and comprehensive way keeping the requirements of teachers and researchers in mind.

Striped catfish or Vietnamese catfish mainly contributes to national aquaculture exports. However, bacterial diseases result in the decrease of striped catfish production efficiency and the most popular disease is hemorrhagic septicemia caused by Aeromonas hydrophila. Bacteriophages or bacterial viruses have been investigated as alternative biological agents to control pathogenic bacterial infections in aquaculture for many decades.

In this study, it was aimed to obtain 3D scaffolds using medical grade chitosan (MC) with a high deacetylation degree (DD ≥ 92.6%) to overcome the spheroid formation of rat adipose tissue derived mesenchymal stem cells (rAdMSCs) on control chitosan (C, DD = 75%–85%) scaffolds. Genipin was used as a biological chemical crosslinker, and glycerol phosphate salt was used both as a pH adjusting agent and physical crosslinker.

This work investigated the effect of adding low concentrations of nano-SiO2 (0.5, 1.0 and 1.5%) in the properties of films based on sodium alginate, to identify lower thresholds in the proportion of the reinforcing agent. It was found that, even in the smallest proportion, thermal stability of the nanocomposites improved significantly (with degradation onset increased by almost 15% compared with the control film).

CRISPR-Cas9 has been developed as a therapeutic agent for various infectious and genetic diseases. In many clinically relevant applications, constitutively active CRISPR-Cas9 is delivered into human cells without a temporal control system. Excessive and prolonged expression of CRISPR-Cas9 can lead to elevated off-target cleavage.

In vitro analyzing the antagonistic activity of seventy native bacterial isolates towards plant tumorigenic Agrobacterium tumefaciens resulted in a selection of eight potential biocontrol agents. These isolates were screened for their antagonistic effect in vitro as well as their efficacy in reducing gall formation in planta.

The rose sawfly, Arge rosae L. (Hymenoptera: Argidae), is one of the most destructive pests of roses grown both indoors and outdoors in Antalya province (south-western part of Turkey). Especially in greenhouse rose cultivation, growers depend heavily on synthetic pesticides to control this pest along with other arthropod pests in their crops. The aim of this study was to evaluate biocontrol potential of some indigenous soil-borne entomopathogenic fungi (EPF) against the pest. In pathogenicity assays, a total of 17 EPF isolates, belonging to three species [Beauveria bassiana (Bals.) Vuill.

In Turkey, Tinocallis (Sappocallis) saltans (Nevsky) on Ulmus glabra Hudson was detected for the first time, and it was determined that it caused a considerable amount of damage. The study was conducted for the purpose of determining the usability of enthomopathogens in the control against it, while avoiding the negative effects of chemicals on the environment and human health. A total of 12 bacteria strains were tested for control efficacy and verified: Brevibacillus brevis (2), Bacillus thuringiensis (1), Bacillus thuringiensis subsp. kenyae(2), Bacillus thuringiensis subsp.

In this study, silver nanoparticle (AgNP) synthesis was carried out using Onosma sericeum Willd. aqueous extract for the first time, with a simple, economical, and green method without the need for any other organic solvent or external reducing or stabilizing agent. A variety of AgNPs, all of different particle sizes, were synthesized by controlling the silver ion concentration, extract volume, temperature, and pH. It was determined that the optimum conditions for AgNP synthesis were 1 mM AgNO3 , pH 8, 25 °C, 20 g/200 mL extract, silver nitrate, and extract ratio 5:1 (v/v).
