A total of 118 isolates thought to belong to the genus Penicillium based on morphological features were obtained from the Fungus Testing Laboratory at the University of Texas Health Science Center in San Antonio (United States). The isolates were studied phenotypically using standard growth conditions There are over 300 species of Penicillium. It is perhaps best known as the fungus (P. Chrysogenum) that produces penicillin, a molecule that has saved countless lives as an antibiotic. Many. Penicillium sp., under low temperature conditions. Our previous study reported the biodegradation of alkyl-phenols by Penicillium sp. CHY-2 isolated from Antarctic soil.18 Consequently, the present work demonstrates the ability of Penicillium sp. CHY-2 to degrade hydrocarbons and PAHs under low temperature conditions and suggests that. Growth of the fungus decreased by increasing or decreasing the pH level from the natural level. Aspergillus flavus and Penicillium chrysogenum showed maximum growth at temperature 30°C. The fungus grew at the temperature range of 10-35°C

Filamentous fungi Penicillium sp. have received much attention as potential candidates for the degradation of a wide range of PAHs. 13 The rapid growth rate, ability to grow under different environmental conditions, and ability to utilize a wide range of substrates as carbon and nitrogen sources enhanced the application of Penicillium sp. in. In some other sp. of Penicillium, the peridium is compact and pseudoparenchymatous. The asci are borne singly and terminally on one-celled lateral branches of the ascogenous hyphae within it. The cleistothecium of Penicillium or Aspergillus represents the following three generations: (i) Parent haplophase

Penicillium sp. KC6-W2 Penicillium strain KC6-W2 was the most effective inoculant at increasing plant growth, providing significant PGP in seven of the nine experiments presently described. Inoculation of seed with Penicillium sp. KC6-W2 increased the growth of each of the three different plant species across a range of soil types and was the. (PTCC: 5224) and Penicillium sp. (PTCC: 5224) in vitro was measured on historical papers. The aw of the media was controlled with glycerol. Findings and Conclusion: The most important factor influencing the growth of the above mentioned fungi is water activity, then temperature and finally pH. Therefore Penicillium sp. was detected in endosperm with bran but not in embryo. Gaseous chlorine dioxide (ClO 2) effectively inhibited growth of Penicillium sp. at concentration of 5 to 20 μg/ml. As treatment duration was extended from 1 to 3 h, growth of Penicillium sp. was completely suppressed even at 10 μg/m

Furthermore, Penicillium sp. also produce antimicrobial compounds that could control a wide spectrum of microorganisms (Komai et al ., 2006; Wang et al ., 2008). In this study, we reported the screening and isolation of endophytic fungi from healthy dragon fruit plant design, under previously defined cultivation conditions. After biosynthesis, the samples of cultivation media were analysed and antifungal activity of each cultivation broth was examined against a Penicillium sp. In order to investigate the effects of chosen factors (glycerol, NaNO 2 and K 2 HPO 4 content) on appropriately selected response Penicillium chrysogenum (also known as Penicillium notatum) is the source for penicillin, the first antibiotic. Penicillin works against gram-positive bacteria, such as Staphylococcus and Pneumococcus by disrupting bacterial cell wall synthesis-- crosslinking of the peptidoglycan polymers is. Material/methods: A total of 100 isolates previously identified as Penicillium sp. were received from the Fungus Testing Laboratory at the University of Texas Health Science Center in San Antonio (USA).
