Abstract:
... An important area of physiology of the honeybee (Apis mellifera) is chemical communication between individuals and castes in the swarm, which maintains its integrity and function. The highly complex social organization of honeybees is mediated through pheromones. Releaser pheromones cause rapid changes in the behaviour of the recipient, while primer pheromones have relatively slow and long-term ef ...

Abstract:
... The constituents of the volatile oil of air-dried aerial parts of Mentha pulegium L. (Lamiaceae) plants wildly growing in Northwest Iran were analysed by GC/MS. 46 components were identified, comprising 96.6% of the essential oil. Monoterpenes (78.9%) were the main class of the identified components followed by a minor proportion of sesqui-
terpenes (11%). Oxygenated monoterpenes (75.3%) were ...

Abstract:
... Carbon monoxide (CO), while a potent toxin, is also a key intermediate in major autotrophic pathways such as methanogenesis and acetogenesis. The ability of purple sulfur bacteria to use CO as an energy source was first described by Uffen in 1976. The prototype extremely thermophilic carboxydotroph Carboxydothermus hydrogenoformans was described in 1991. Eight bacteria and one archaeon that utiliz ...

Abstract:
... The spruce coneworm, Dioryctria abietella Denis & Schiffermüller (Lepidoptera: Pyralidae), is a major pest in spruce seed orchards in Europe. Initial work on its pheromone ecology reported significant attraction of males to (9Z,11E)‐tetradecadienyl acetate (9Z,11E‐14:OAc), but this compound appeared to be a very weak attractant in field trials. In this study, we show that a second female‐pr ...

Males of several species in the large cerambycid beetle subfamily Lamiine, native to South and North America, are known to produce aggregation-sex pheromones composed of three related structures: the sesquiterpene catabolic product geranylacetone, its corresponding alcohol (known as fuscumol), and the acetate ester of the alcohol (fuscumol acetate). Here, we show that males of two lamiine species ...

... Ionic liquids (ILs) have been considered as promising alternatives to traditional reagent for lignocellulosic biomass pretreatment because of their tunable physicochemical and “green” properties. In the study, the influence of 1-Butyl-3-methylimidazolium acetate ([Bmim]acetate) pretreatment of giant reed on H₂ yield improvement via photo-fermentation (PF) was evaluated. Under the optimal pretreatm ...

The oxidative depolymerization of alkali lignin (AL) in 1-ethyl-3-methylimidazolium acetate ([C₂C₁im]OAc) system without additional catalyst was investigated under mild conditions (initial O₂ pressure of 1.5 MPa, 80 °C–100 °C). Compared with other ionic liquids (ILs), the cooperation of imidazolium cation and acetate anion successfully enhanced AL conversion. Among the investigated imidazolium ace ...

Pretreatment with ionic liquids (IL) such as 1-ethyl-3-methylimidazolium chloride or acetate is an effective method for aiding deconstruction of lignocellulosic biomass; however, the residual IL remaining in hydrolysates can be inhibitory to growth of ethanologenic or oleaginous yeasts that have been examined in the literature. The aim of this study was to identify oleaginous yeasts that are toler ...

Previous research has shown that induction of an accessory corpus luteum (CL) by administration of gonadotrophin-releasing hormone (GnRH) on Day 5 increases circulating progesterone and reduces pregnancy loss between Days 33 and 60 in heifers receiving invitro-produced (IVP) embryos. Therefore, the objective of the present study was to determine whether timing of induction of an accessory CL influ ...

Abstract:
... Alpacas, like other camelids, are classified as induced ovulators because an external stimulus is required for the occurrence of ovulation. Recent studies have identified the β-nerve growth factor (β-NGF), a protein present in the seminal plasma (SP), as responsible for inducing ovulation in this species and having potent luteotropic function. We speculate that SP can be used in reproductive biote ...
