The present experiment was performed to study the peri-implant tissue response to non-submerged (1-stage) and initially submerged (2-stage) implant installation procedures. 6 beagle dogs were used. All mandibular premolars and the 1st, 2nd and 3rd maxillary premolars were extracted. After 3 months of healing, 3 fixtures of the Astra Tech System were installed and submerged in the right (or the ...

Investigations on Ganoderma lucidum fermentation suggested that the responses of the cell growth and metabolites biosynthesis to pH and dissolved oxygen tension (DOT) were different. The ganoderic acid (GA) production of 321.6 mg/L was obtained in the pH-shift culture by combining a 4-day culture at pH 3.0 with the following 6-day culture at pH 4.5, which was higher by 45% and 300% compared wit...

Stoichiometric homeostasis of element composition is one of the central concepts of ecological stoichiometry. We analyzed concentrations of macroelements (C, N, P, Ca, K, Mg, S), microelements (Cu, Fe, Mn, Mo, Ni, Zn) and beneficial elements (Na, Se, Si) in submerged macrophytes, water and sediments across 20 Yunnan plateau lakes. We predicted that tissue element composition in submerged macrop...

Pigments from bacteria, fungi, yeast, cyanobacteria, and microalgae have been gaining more demand in the food, leather, textile industries due to their natural origin effective bioactive functions. Mass production of microbial pigments using inexpensive ecofriendly agro-industrial residues is current research low cost, origin, waste utilization, high pigment stimulating characteristics. A wide ...

Two hundred thirty four fungal strains were isolated by baiting method, for their feather degradation and keratinase producing ability. Fungi were tested on solid milk agar plates and in submerged culture. Maximum clearing zone was made by Chrysosporium indicum (7mm) on solid agar plates. The highest keratinase production was found in case of Acremonium strictum (74.40Unit/mL & 124.72 Unit/ml i...

The effects of selected metals (Mg, Mn, Zn, and Fe) on 3-acetyldeoxynivalenol (3-ADN) production by Fusarium graminearum R2118 and on its mycelial growth were investigated by using a two-stage submerged-culture technique. In certain concentrations ranges, Mg and Fe stimulated growth but suppressed 3-ADN production; at other concentrations, Mg, Fe, and Zn suppressed growth but stimulated 3-ADN p...

Kozakia baliensis belongs to the family Acetobacteraceae and was described for the first time in 2002. These acetic acid bacteria are able to produce acetic acid from various carbon sources and 2- and 5-keto-d-gluconate from glucose. The novel K. baliensis strain SR-745 was isolated from a pineapple fruit bought in a German supermarket. The strain produces large amounts of organic acids when gr...

Xylanase execute a large variety of function and have many important in biotechnological application. Its application in paper industry, pulp industry, increases the self life of bread, food ndustry. The production of xylanase was investigated in submerged culture of Aspergillus niger. This study was carried out in isolation and screening of xylanase enzyme from the Aspergillus niger fungus. Th...

The analysis of the propagation phase plays a fundamental role in the assessment and forecasting of risks related to the occurrence of submerged and coastal landslides. At present there are few numerical models able to simulate the propagation of such a type of events. This paper presents fully 3D models and approaches developed by the authors and suitable for the simulation of both completely ...

A submerged biofilter (SBF) with 0.1 m of filter medium was maintained without backwash at four different water temperatures (14°C, 18°C, 22°C and 26°C) in four different recirculating systems stocked with green tiger shrimp (Penaeus semisulcatus). The ammonia removal profile and nitrification performance of the SBF was evaluated at feed loading rates of 2.65 g day at 14°C, 5.52 g day at 18°C, ...
