This study examines the effectiveness of mycorrhizal Rhizoctonia resistance induction in Phalaenopsis amabilis against Fusarium sp. Fusarium solani is known as pathogens that attack many orchids P. amabilis (Chung et al., 2011) compared to other pathogenic fungi. Attack of Fusarium sp. will cause rot and yellow colored leaves. Until now there has been known as a biological control orchid against Fusarium sp. In this study tested the endurance locations in Sleman and Surakarta to see the effectiveness of a good orchid growth induced by Rhizoctonia mycorrhizal or not to attack by Fusarium sp. The results of the study showed that mycorrhizal Rhizoctonia able to inhibit the attack of Fusarium sp. It is shown by the value of the index of disease resistance  (DSI) in P. amabilis orchid mycorrhizal Rhizoctonia induced lower than that not induced. Mycorrhizal Rhizoctonia induction results in Sleman provide a more real than mycorrhizal Rhizoctonia induction in Surakarta.

Citrus pulp is a highly abundant by-product of the citrus industry. The aim of this study was to assess the effects of replacing extruded maize (EM; 20% of total diet) by dried citrus pulp (DCP; 20%) in a mixed diet on rumen fermentation and microbial populations in Rusitec fermenters. The two diets contained 50% alfalfa hay and 50% concentrate, and the same protein level. Four Rusitec fermenters were used in a cross-over design with two 13-d incubation runs. After 7-d of diet adaptation, diet disappearance, fermentation parameters, microbial growth, and microbial populations were assessed. Fermenters receiving the DCP showed greater pH values and fiber disappearance (p < 0.001) and lower methane production (p = 0.03) than those fed EM. Replacing EM by DCP caused an increase in the proportions of propionate and butyrate (p < 0.001) and a decrease in acetate (p = 0.04). Microbial growth, bacterial diversity, and the quantity of bacteria and protozoa DNA were not affected by the diet, but the relative abundances of fungi and archaea were greater (p < 0.03) in solid and liquid phases of DCP fermenters, respectively. Results indicate that DCP can substitute EM, promoting a more efficient ruminal fermentation.

The suitability of Mugil liza for cold smoking was evaluated and the effect of four different salting treatments on physicochemical, microbiological, and sensory characteristics was assessed. The addition of sucrose (3%) and acetic acid (0.5%) to the brine lead to fillet dehydration with lower NaCl penetration, combined with higher reduction of pH. Brining at refrigerated temperature (5 ± 1 ℃) instead of room temperature (16 ± 2 ℃) was more effective in preventing microbial growth. Loads of bacterial groups assessed in all smoked samples were below 100 CFU/g and the aw, moisture, NaCl, and pH values achieved were within the typical stability range of smoked fish products. The obtained products were characterized by the smoked aroma and salty taste, differing in 7 of the 21 evaluated descriptors. The use of acetic acid in brine formulation showed an effect over color and texture descriptors. The affective test indicated the overall acceptability of products, being preferred the samples treated in the lowest NaCl concentration (5%).

Ikan pindang adalah salah satu olahan yang sangat disukai oleh masyarakat Indonesia. Hal ini dapat dilihat dari produksi ikan pindang yang setiap tahunnya mengalami peningkatan. Sebagai contoh di Kabupaten Bogor, produksi ikan pindang pada tahun 2013 sebesar 3.643,56 ton, meningkat menjadi 10.334,44ton pada tahun 2015. Ikan pindang disisi lain, sangat mudah mengalami kemunduran mutu disebabkan masih tingginya kadar air, pengemasan yang tidak memenuhi standar serta proses pengolahan yang pada umumnya kurang menerapkan prinsip sanitasi yang baik. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi kapang yang tumbuh pada bandeng presto. Sampel Bandeng presto diambil dari CV. Cindy Group. Kapang diisolasi dengan metode pengenceran bertingkat menggunakan media DRBC (Dichloran Rose Bengal Chloramphenicol Agar), kemudian diidentifikasi secara morfologi menggunakan media Malt Extract Agar dan Czapek’s Yeast Extract Agar. Nilai Aktivitas air (aw) bandeng presto memiliki kisaran rata-rata 0,96 – 0,97. Secara makroskopis terlihat adanya pertubuhan kapang pada permukaan ikan bandeng presto setelah penyimpanan selama 3 hari pada suhu ruang (20-250C). Sebanyak 5 isolat kapang diisolasi dari ikan pindang sampel bandeng presto. Hasil identifikasi secara mikroskopis diketahui bahwa kapang yang tumbuh ada ikan pindang tersebut adalah spesies Penicillium citrinum, Eurotium chevalieri, Fusarium solani, Fusarium sp, dan Cladosporium sp. Kadar aw ikan pindang resto yang masih tinggi (0,96-0,97) menyebabkan ikan pindang mengalami pembusukan yang diakibatkan oleh bakteri.

Drought of fruits and vegetables is a promising food processing technology that increases shelf life of products for almost a year. It is a value of process that can save the losses of seasonal agriculture products. The Solar dryers can be used to carry food dehydration without on electricity. India is most of agriculture-dependent country. Fruits and vegetables are an basically part of human diet providing micronutrients, vitamins, enzymes, and minerals. Most fruits and vegetables it content moisture and water activity. This makes it is vulnerable to bug and other spoilages due to biochemical reactional, such as enzymatic activity, respiration, and senescence. Then, preventive measures are taken to lower water activity; drying or dehydration is we such one method. Drying is a process of mostly used removal of water from the food to in biochemical processes and microbial growth. Drying increases the service life of the product, so that it can be available during off season.

Interesting Alternative

The installation of in-mill biological treatment for reducing the concentration of dissolved organic matter and microbial growth in the whitewater system h as been shown to be an interesting alternative for facilitating further closure of paper mill water circuits. In the present study the possibility of operating biological treatment of whitewater from different types of paper production under the environmental conditions prevailing in respective whitewater system, i.e. temperatures between 37 and 52°C and pH-values from 3 to 8. It was shown that high removals of soluble COD, 70-90%, could be achieved even at high temperatures and non-optimal pH-levels. Laboratory scale whitewater systems operated with and without a bioprocess were used for studies of the effect of a bioprocess on key parameters such as slime growth, spore formers and odorous compounds. The introduction of a bioprocess in the whitewater circuit effectively lowered the amount of soluble organic matter and eliminated odorous VFA. However, the operation strategy and control of the bioprocess showed to be crucial, especially the dosing of nutrients, in order to avoid increased rather than decreased biofilm growth in the whitewater system.

Salt Level

Five pork carcasses were used to determine the effects of hot boning and various combinations of salt (0, 1.5 or 3.0%) and a phosphate mixture (0 or 0.5%) on microbial, TBA and pH values of preblended pork (preblends). In both HB (hot boned within 2 h postmortem) and CB (conventionally boned at 24 h postmortem) preblends, salt increased (P&lt;0.05) TBA values and decreased (P&lt;0.05) psychrotrophic counts, whereas phosphate increased (P&lt;0.05) pH and decreased TBA values. Salt level could be reduced from 3.0 to 1.5% in preblends without any storage problems if phosphate (0.5%) was included. Phosphate (mixture pH 7.2) seemed to have little influence on microbial growth of preblends during cooler storage.

Ice Pack

The paint effluent was collected directly from one paint industry in Lagos from the releasing tank into a sterile bottle, and was transported with the use of ice pack to the laboratory to prevent contamination. Paint effluents contain a complex mixture of chemicals which may have potential threats to biota. The present study was carried out to assess the potential impacts of paint effluents entering the aquatic environment. The concentration of the toxicant was varied into 1.25mls/l, 2.50mls/l, 3.75mls/l, 5.0mls/l and 6.25mls/l into the separate tanks to pollute Claris garipenius. The heavy metals present in the paint effluent were lead (0.34±0.01ppm) and zinc (1.20±0.01 ppm). The volume of water used was 20 litres in the aquaria and concentration of the toxicant was varied into 1.25mls/l, 2.50mls/l, 3.75mls/l, 5.0mls/l and 6.25mls/l into the separate tanks containing the fish. Differences were observed in pH and the BOD5 of the fish water which were monitored for 96hours. There were increases in the fungal population with increase in the treatments of the pollutant. Fungi were isolated from the polluted fish aquaria and parts of the harvested fish. The fungi isolated include; Penicillium italicum, Aspergillus niger, Aureobasidium pullans, Articolospora inflata, Trichosporon sp, Mucor mucedo Rhodotorula rubra Rhizopus stolonifer Candida albicans. The fish water affect the pH, BOD5, fungal loads, fungal types, leads to bioaccumulation of heavy metals in catfish. The overall result of the research requires that care should be taken in discharging the effluent into the water bodies so as to minimise its impact on aquatic organisms.
