Abstract Background The study evaluated the growth performance, haemabiochemical and antioxidant profile of two breeds of rabbits fed diets containing varying levels of Rhizopus stolonifer fermented cocoa pod husk meal (FCPHM). Cocoa pod husk meal was taken through solid-state fermentation for a period of 2 weeks using Rhizopus stolonifer as its starter culture. One hundred and eighty, 5-week-old unsexed weaned rabbits 90 New Zealand white (NZW) and 90 Chinchilla (CHL) were randomly allocated into three dietary treatments, Diets I, II and III (0%, 12.5 and 25%FCPHM, respectively), and were arranged in a 2 × 3 factorial design (2 breeds and 3 diets) of a randomized block design. Results The study showed that the breed effect and dietary treatment were significant (p < 0.01) for total weight gain and feed conversion ratio with NZW breed fed 12.5% FCPHM having higher values than CHL breed. Serum total protein concentration was significantly (p < 0.05) influenced by the dietary treatment, while alanine aminotransferase, globulin and total protein concentrations were significantly (p < 0.01) affected by the breed effect. The interactive effect of breed and dietary treatment was only significant (p < 0.05) for serum albumin concentration. Malondialdehyde concentration was significantly influenced by both dietary treatments (p < 0.05) and breed (p < 0.001) factors. Conclusion It was observed that CHL rabbits were more predisposed to stress than the NZW rabbits as indicated by the lipid peroxidation values, and according to this present finding, 12.5% FCPHM is recommended as active feed ingredient in rabbit diets.

Potato, (Solanum tuberosum (L.)) is a valuable stable food grown for its edible starchy tuber. This work was aimed to test the efficacy of indigenous plants extract for controlling wet rot disease of potato caused by Rhizopus stolonifer. The fungi was isolated from decaying bread and grown on potato dextrose agar (PDA) plates. Ripe Ginger (Zingiber officinale) (rhizome), West African pepper (Piper guineense) flower, Clove (Syzygium aromaticum) seed were collected from Muda Lawal Market, Bauchi, Nigeria. The dried seed were grinded using blender to get ginger, clove and West African pepper powder. Radial mycelia growth of Rhizopus stolonifer varied significantly (p≤0.01) with the application of different plant extracts. Mycelia growth of Rhizopus stolonifer was found to be low in potatoes treated with West African pepper (0.26 cm) than those treated with ginger (0.32 cm) and clove (0.33 cm). However, as observed from the result, ginger and clove did not differ statistically in their effect on Rhizopus mycelia growth (in vitro) but showed a better effect than the control treatment (0.40 cm). Inhibition of the mycelia growth by the West African pepper seed extract is an indication that it is fungicidal.

The predominant diseases of the commercial kumara (Ipomoea batatas) or sweetpotato crop are caused by fungal pathogens The field disease pink rot results from infection by the fungus Sclerotinia sclerotiorum Lesions form on vines but may spread down stems to the roots The widespread nature of this disease in sweetpotato appears peculiar to New Zealand Scurf is a disease caused by Monilochaetes infuscans which occurs in the field but may proliferate amongst stored roots The disease causes a superficial discolouration of the root surface which is mainly cosmetic but can also increase root water loss in storage Infection by Ceratocystis fimbriata produces a disease known as black rot The disease can be transmitted amongst plants at propagation but is particularly rampant amongst roots in storage This disease is readily transmitted and can cause severe economic loss Fusarium oxysporum causes surface rots in stored roots characterised by light to dark brown lesions that tend to be firm dry and superficial The lesions may be circular and centred on wounds caused by insects or mechanical damage at harvest Soft rot caused by Rhizopus stolonifer generally occurs in roots after they are washed and prepared for the market Fungal infection occurs through wounds or bruised tissue producing distinctive tufts of white fungal strands and black spores

The safety and efficacy of a drug is based on its metabolism or metabolite formed. The metabolism of drugs can be studied by different in vitro models, among which microbial model became popular. In the present study, eight microbes were screened for their ability to metabolize phenobarbital in a manner comparable to humans with a model to develop alternative systems to study human drug metabolism. Among the different microbes screened, a filamentous fungi Rhizopus stolonifer metabolized phenobarbital to its metabolite which is used for further pharmacological and toxicological studies. The transformation of phenobarbital was identified by high- performance liquid chromatography (HPLC). Interestingly, Rhizopus stolonifer sample showed an extra metabolite peak at 3.11min. compared to its controls. The influence of different carbon sources in media used for growth of fungus, on metabolite production was studied, to find its effect in production of metabolite as the carbon source may influence the growth of the cell.

The physicochemical and antimicrobial properties of cocoa pod husk (CPH) pectin intended as a versatile pharmaceutical excipient and nutraceutical were studied. Properties investigated include pH, moisture content, ash values, swelling index, viscosity, degree of esterification (DE), flow properties, SEM, FTIR, NMR, and elemental content. Antimicrobial screening and determination of MICs against test microorganisms were undertaken using agar diffusion and broth dilution methods, respectively. CPH pectin had a DE of 26.8% and exhibited good physicochemical properties. Pectin had good microbiological quality and exhibited pseudoplastic, shear thinning behaviour, and high swelling capacity in aqueous media. The DE, FTIR, and NMR results were similar to those of previous studies and supported highly acetylated low methoxy pectin. CPH pectin was found to be a rich source of minerals and has potential as a nutraceutical. Pectin showed dose-dependent moderate activity against gram positive and gram negative microorganisms but weak activity against Listeria spp. and A. niger. The MICs of pectin ranged from 0.5 to 4.0 mg/mL, with the highest activity against E. coli and S. aureus (MIC: 0.5–1.0 mg/mL) and the lowest activity against A. niger (MIC: 2.0–4.0 mg/mL). The study has demonstrated that CPH pectin possesses the requisite properties for use as a nutraceutical and functional pharmaceutical excipient.
