Copper tolerant fungi are known for more than 60 years but the complete mechanisms of copper tolerance by these fungi are still not fully understood. Copper tolerance has previously been linked to oxalic acid excretion by copper tolerant brown rot fungi. The oxalic acid then reacts with copper in the wood to form an insoluble and therefore less toxic copper oxalate. It has been suggested that c...

Bovine chymotrypsinogen Q! was examined for N-terminal groups by Rovery et al. (l), using both the dinitrophenyl (DNP) and the phenyl isocyanate techniques (2, 3). Their failure to find evidence for any such group, together with the absence of a C-terminal residue reactive towards carboxypeptidase (4), suggested that this protein consists of one or more cyclic peptide chains. Evidence has now b...

background: phenol and its derivatives like dinitrophenol and pentachlorophenol (carbolic acid) are widely used as insecticides, but they are very toxic substances. phenol is a general protoplasmic poison with corrosive local effects that denature proteins. poisoning with phenol compounds may occur by ingestion, inhalation, and absorption through skin. in this report we presented the toxicity e...

Brown eggs have gradually entered the traditional white-egg markets as a distinctive mode for packaging specialty eggs. A test was conducted at the Brigham Young University Sensory Laboratory (Provo, UT) to understand how consumers view attributes of the brown egg relative to the white egg. The objectives were to see how the consumer viewed properties of eggs by color and to examine the prefere...

Recently, the Q biotype of tobacco whitefly has been recognized as the most hazardous strain of Bemisia tabaci worldwide, because of its increased resistance to some insecticide groups. As an alternative control agent, we selected an Isaria javanica isolate as a candidate for the development of a mycopesticide against the Q biotype of sweet potato whitefly. To select optimal mass production med...

The aim of this study was to evaluate the in vitro antimicrobial activity of Brazilian brown propolis as an intracanal medication against Enterococcus faecalis. Thirty dentin discs prepared from intact freshly extracted bovine maxillary central incisors were infected with E. faecalis for 21 days. The specimens were distributed into six groups according to the medicament used as follows: G1- cal...

The research carried out at the Experimental Station of University Agriculture in Krakow aimed to assess utility value turf a lawn sown with “Super Trawnik” mixture. experimental factor was spraying an amino acid preparation form AMINO ULTRA Fe-20 fertilizer three doses: 0.3, 0.5, and 0.7 dm3·ha−1. iron tested is complexed glycine, natural plant transporter microelements. A total 60 g (variant ...

Extracts of four species of seaweeds, Ulva lactuca L. (green), Liagora farinosa Lamouroux (red), Padina pavonia L. and Turbinaria ornata Turn (brown), were screened for their antimicrobial, and antimalarial activities, and binding affinity for human opioid receptors. Phytochemical analysis led to the isolation and identification of 10 constituents: fucosterol, stearic acid, palmitic acid, palmi...

Distribution, abundance, habitat selection, and activity of bats in Wayne National Forest, Ohio, were studied during the winters and summers of 1979 and 1980. Methods included winter surveys of abandoned mines and mist netting of riparian sites in summer. Four species of bats were found hibernating in 23 of 65 coal mine shafts examined, and big brown bats, Epteskus fuscus, were most abundant. M...
