Gelatin reinforced with cncs as nanocomposite matrix for Trichoderma harzianum KUEN 1585 spores in seed coatings
Get PDFIncreasing interest on sustainable agriculture has led to the development of new materials
which can be used as seed coating agents. In this study, a new material was developed based on
gelatin film reinforced with cellulose nanocrystals (CNC) which was further used as nanocomposite
matrix for Trichoderma harzianum KUEN 1585 spores. The nanocomposite films were characterized
by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron
microscopy (SEM), showing the formation of new hydrogen bonds between the components with a
good compatibility between them. Measurements of water contact angles and tests of water vapor
sorption and swelling degree revealed an improvement in the water vapor absorption properties
of the films as a result of their reinforcement with CNC. Furthermore, by adding the Trichoderma
harzianum KUEN 1585 spp. in the seed coating material, the germination percentage, speed of
germination and roots length of the corn seeds improved. The polymeric coating did not inhibit the
growth of T. harzianum KUEN 1585, with this material being a good candidate in modern agriculture

Technical and functional characteristics of the irrigation system from S.C. Livada mere de Iteşti s.r.l. Bacău
No full textHigh-performance agriculture is achievable based on investment: starting from a high-quality seed or propagating
material, ensuring optimum conditions for growth and development to reach, in the end, a higher value for production.
By providing the crops and plantations with the water need, a significant increase in productions obtained. To this
purpose, it is necessary to invest in irrigation systems, because the annual rain fall is not sufficient or we do not benefit
from it in the critical phenophases of the crops. In the fruit-growing farm SC Livada mere de Itesti SRL Bacau, the drip
irrigation system, which is currently considered the best method for irrigating the orchards, is installed. Designed on an
area of 17 acres cultivated with apple trees, of different varieties, the irrigation system consists of: front assembly,
transport-distribution pipe, connecting pipes, and watering pipes provided with droppers. By accessing European funds,
through the PNDR, it was possible to make are conversion investment of the fruit plantation, to equip it with a drip
irrigation system, as well as to modernize the fleet of agricultural machines and equipment. The work aims to present an
irrigation development model, a model successfully implemented, thanks to the funds
Bovine papillomavirus type 2 detection in blood of asymptomatic limousine breed cattle
Get PDFBovine Papillomaviruses (BPV) are double-stranded DNA viruses, known to infect ruminants and equines. In bovines,
up to 29 genotypes of BPV have been described and classified based on the nucleotide sequence identity of L1 open
reading frame. The aim of this study was to detect bovine papillomavirus type 1, 2 and 4 in the blood collected from
clinically healthy Limousine cattle, with history of papillomatosis. Fourteen blood samples were collected from a cattle
farm, located in Suceava County, Romania. The viral DNA was extracted using PureLink™ Genomic DNA Mini Kit,
following the manufacture’s instruction. Papillomavirus DNA was confirmed by PCR, using type specific primers for
BPV-1 L1 gene, BPV-2 L2 gene and BPV-4 E7 gene detection. PCR products were electrophoresed on 2% agarose gel
and visualized with UV transillumination. None of the blood samples tested positive for BPV-1 nor BPV-4. A fragment
of 164 base pairs corresponding to BPV-2 L2 gene was amplified in 10 (92,2%) samples, while 4 samples were
negative (7,8%). This is the first time when in Romania, to authors best knowledge, BPV-2 is detected in blood samples
collected from cattle. Moreover, BPV-2 persists and is maintained in the bloodstream of the asymptomatically cattle,
representing a potential reservoir of viral infection
Efficiency of some screening methods used in monitoring the quality of vegetable substrates and the presence of mycotoxins
No full textThe purpose of this study was to evaluate the effectiveness of screening methods applied in the analysis of plant products
(cereal seeds, feed, hay, etc.) used in agriculture and animal husbandry. Their screening can be done both during the
harvesting season aswell as during their storage for the cold season. Information regarding the physico-chemical parameters
and mycotoxicological load may be obtained by applying this rapid screening techniques. Near-infrared spectroscopy (NIRS)
screening techniques can provide a quick result regarding the quality of plant products. In this study, the efficiency of using
the Perten FT-NIR Analyzer in determining the physico-chemical parameters was tested. The sample were scanned and the
values were provided shortly after. The analyzed products were also tested from a mycotoxicological point of view by
identifying the presence of different types of mycotoxins in plant products by applying thin layer chromatography (TLC). The
use of fast screening methods leads to lower costs, elimination of toxicity and shortening of the time to results
The effect of myco‐biocontrol based formulates on yield, physiology and secondary products of organically grown basil
No full textThe development of organic farming as a result of increasing consumer preference for
organic food has led to the development and registration of new pest‐control products for certified
organic production. In this study, the effects of three biocontrol products containing spores and
mycelium of Arthrobotrys oligospora—Artis®, Beauveria bassiana—Bora®, and Coniothyrium minitans—
Öko‐ni® were tested on four basil (Ocimum basilicum L.) cultivars: ‘Aromat de Buzau’, ‘Serafim’,
‘Macedon’ and ‘Cuisoare’. The application of Öko‐ni® increased basil yields by 8% relative to Control.
The application of Bora® increased chlorophyll content of basil leaves by 2% and the activity of
photosynthesis by 66% relative to the Control. Basil essential oil (EO) content was increased by 18%
with the application of Artis® and by 34% with the application of Bora® and Öko‐ni®, respectively.
The content of phenolic compounds analyzed by HPLC varied; caffeic acid concentration was
higher in the plants treated with Öko‐ni®, hyperoside, isoquercitrin and rutin concentrations were
higher in those treated with Artis®, while the quercitrin content was higher in Bora®‐treated plants.
The two main EO constituents that were identified were linalool and methyl chavicol in ‘Aromat de
Buzau’, linalool and eugenol in ‘Serafim’, neral and geranial in ‘Macedon’, also linalool and eugenol
in ‘Cuisoare’. The investigated myco‐biocontrol products had positive effects on basil fresh biomass
and EO content and also influenced the content of phenolic compounds
Bacteriological agents in farmed cyprinids from the Prut river basin
Get PDFThe current paper aims to outline what could be the most common bacterial agents that can have a pathogenic effect on
farm cyprinids form the Prut river basin in order to reduce fish health risks and even prevent future disease outbreaks that are
bacterial in nature. Two field works expeditions to Rompescaris farm -Podu-Iloaiei from Iasi county and to Dracșani fish
farm from Piscicola-Botoșani county were undertaken in May 2021 in order to collect biological samples. The
following fish species were harvested: carp (Cyprinus carpio), silver carp (Hypophthalmichthys molitrix) and mirror
carp (Cyprinus carpio var. specularis) using net fishing and the only the specimens with visible lesions or the moribund
ones were collected. The fish that were apparently healthy were released and the ones that were harvested underwent a
clinical, parasitological and bacteriological investigation
Folosirea compozițiilor vegetale pentru zonele cu perioadă scurtă de insolație
Get PDFRecent studies in the field of sustainable urban planning focus on the plant component, favoring the implementation and conservation of plant material at the highest possible level of quality and performance. In order to better understand the ideology of using dendrological and flowering plants in areas with low insolation, we resorted to their use in a proposal to arrange a private garden. The paper aims to present the methods of arranging private or public gardens taking into account, at the time of design, the needs and requirements of the beneficiary and also the elaboration of a proposal in case the space that is going to be arranged has atypical characters. Here reference is made to the way of designing spaces in which the degree of sunlight is reduced and involves treating them as spaces with semi-shade or shade. In the foreground of this work is the way we use shade and semi-shade plants and how the spaces that benefit from a low degree of insolation are capitalized and integrated
The role of sensory evaluation in food quality control, food research and development: a case of cream cheese study
No full textSensory evaluation is a method of analysing, measuring and interpreting sensory perception responses to food, based on
the five human senses, charac terised, in line with other scientific methods of measurement, by precision, accuracy and
sensitivity. The material studied consisted of six varieties of cream cheese purchased on the commercial market and
produced by a usual technological process. The sensory evaluation session involved assessment of colour, aroma,
texture and taste by a group of 20 tasters over three series of tastings. From a ranking point of view, in descending
order of the average scores obtained in the sensory evaluation of the characteristics of appearance, colour, texture,
smell, taste and creaminess, the samples can be classified as follows: Philadelphia (S2), Hochland (S3), LaDorna (S1)
Goldessa (S5), Delaco (S6) and KClassic (S4)
