Polystyrene (PS) is one of the major plastics contributing to environmental pollution with its durability and resistance to natural biodegradation. Recent research showed that mealworms (Tenebrio molitor) and superworms (Zophobas morio) are naturally able to consume PS as a carbon food source and degrade them without observable toxic effects. In this study, we explored the effects of possible food additives and use of worm frass as potential plant fertilizers. We found that small amounts of sucrose and bran increased PS consumption and that the worm frass alone could support dragon fruit cacti (Hylocereus undatus) growth, with superworm frass in particular, supporting better growth and rooting than mealworm frass and control media over a fortnight. As known fish and poultry feed, these findings present worms as a natural solution to simultaneously tackle both the global plastic problem and urban farming issue in a zero-waste sustainable bioremediation cycle.

The antibody responses to toxoids were measured to investigate whether Clostridium perfringens beta and epsilon toxoids induced protective humoral immune responses in buffalos. Total of 24 buffalos were divided into 4 groups (n = 6), beta toxoid, epsilon toxoid, combination and control groups. These buffalo groups were administered each of the designated toxoids. Immunizations in the beta and epsilon toxoid groups induced strong antibody responses. The neutralizing antibody titres from the beta and epsilon toxoid groups were equally log101.2 on day 21 after inoculation whereas there was no antibody titre detected from the control group. A statistically significant (P < 0.01) increase in antibody titre was observed from day 0 to day 14 and 21 after inoculation. The antibody production did not vary significantly due to day of inoculation and toxoid interactions.

Crop losses due to disease are hard to quantify but a fair estimate of that caused in cocoa by pod diseases is around £1500 million per annum. There is, therefore, a strong incentive to control such diseases but the circumstances in which much of the crop is grown are such that effective chemical treatments may not be economically viable. For this reason, good management techniques also have an important part to play.

Effectiveness of a betalains/sorbate curing system versus a conventional nitrite system for color development and control of microbial growth in chicken frankfurters was tested. Normal heat processing involved in the manufacture of frankfurters was successful in reducing cell levels of indigenous aerobic mesophiles, and spore levels of inoculated Clostridium perfringens and Clostridium sporogenes by 1 to 2 log cycles. There were no significant differences in numbers of C. perfringens spores for either treatment after 9 d of storage at 4 or 20°C. The two curing systems tested were also equally effective in controlling growth of C. sporogenes when tested at 20°C over a 9-d storage period. The betalains/sorbate system proved to be more effective in inhibiting growth of aerobic mesophiles over the 9-d storage period at both 4 and 20°C. It is concluded that in chicken frankfurters under the conditions of this experiment, a betalains/sorbate curing system provided the same level of microbiological protection as a nitrite curing system.

Poultry enterprises have sustained rapid development through the last three decennaries. For which reason, higher utilization of antibacterial, either as therapeutic or growth promoting agents, has been accepted. Owing to the concern of developing bacterial resistance among populations towards antibiotic generations, accumulation of antibacterial remaining’s in chicken products and elevating shopper request for outcomes without antibacterial remaining’s, looking for unconventional solutions that could exchange antibacterial without influencing productiveness or product characters. Using natural alternatives including ginger, garlic prebiotics, organic acids, plant extracts, etheric oils and immune stimulants have been applied to advance the performance, hold poultry productiveness, prevent and control the enteric pathogens and minimize the antibacterial utilization in the poultry production in recent years. The use of a single replacement or ideal assemblage of different choices besides good supervision and livestock welfare may play a basic role in maximizing benefits and preserving poultry productiveness. The object of this review was to support an outline of the recent knowledge on the use of the natural replacements (ginger and its derivatives) in poultry feed as feed additives and their effects on poultry performance, egg and meat quality, health as well as the economic efficiency.

The influence of four different harvest times on the bull’s eye rot of ‘Cripps Pink’ apple caused by Neofabraea spp. was investigated in two orchards harvested at four different times. In addition, a control strategy based on chemical treatments performed in preharvest or postharvest was evaluated. Regression analysis between harvest time and disease incidence revealed high r2 values (>0.75). All preharvest fungicide treatments significantly (P < 0.0085) reduced the bull’s eye rot incidence; however, thiophanate-methyl (achieving >87% control) was more effective than a mixture of pyraclostrobin and boscalid (<80.7%) or fludioxonil (<57.6%), in all trials. Compared with nontreated control fruit, a postharvest treatment with the ethylene inhibitor 1-methylcyclopropene (1-MCP) halved the incidence of infection in three of four experiments. However, a combination of two preharvest treatments with a mixture of pyraclostrobin plus boscalid and one postharvest 1-MPC treatment suppressed bull’s eye rot to a significantly (P < 0.00001) greater degree (achieving >87.5% control) than the single treatments with pyraclostrobin and boscalid (<65%) and 1-MCP (<80%) tested alone.

Plastic Carbon

Polystyrene (PS) is one of the major plastics contributing to environmental pollution with its durability and resistance to biodegradation. Recent research has found mealworms ( Tenebrio molitor) and superworms ( Zophobas morio) to be able to utilize PS as a carbon food source and degrade them without toxic effects. In this study, the effects of food additives on plastic consumption augmentation were studied, with small additions of sucrose and bran found to increase PS consumption. To close the plastic carbon cycle, we also evaluated the use of worm frass for dragon fruit cacti ( Hylocereus undatus) growth and found that superworm frass supported rooting and growth better than mealworm frass and control media over a fortnight. Superworms, apart from being known fish and poultry feed, have been shown to be a suitable natural solution to the PS plastic problem that can support plant growth towards a zero-waste sustainable bioremediation cycle.

This study evaluated the isolation, molecular typing and celular proliferation of C. perfringens in small intestine of cattle and sheep distributed in case and control groups. In the case group, out of the 61 bovine samples analyzed, C. perfringens was isolated in 29 (47.54%) and in 4 (33.34%) from 12 sheep samples. In the control group, we did not isolate the microorganism in the bovine samples (73 samples), however it was possible in 5 (20.83%) out of the 24 sheep samples.  All isolates (100%) were classified as type A, and cell quantification showed that in control group, all cattle samples resulted in 10 CFU/g of intestinal content while in the study group presented a median value of 104 CFU/g, varying from 10 CFU/g through 108 CFU/g. In ovine group there was a clear divison of values between the two groups. Molecular typing corroborates with other studies regardin the epidemiological importance of type A in enterotoxaemia in ruminants, thus cellular quantification data allow us to conclude that healthy animals present a basal level of C. perfringens lower than 10 CFU/g that does not allow its isolation.
